We know you’ll fall in love with our Cosmopolitan style lamp and it’s sleek straight lines, rectangular contemporary structure, and clean appearance.

The Cosmopolitan lamp is not just a lighting fixture–it’s a piece of art that brings together history, design, and functionality. With its six-sided design and elegantly angled roof, this lamp is a unique blend of architectural precision and aesthetic appeal.

Inspired by the late 19th-century summer pavilions, the Cosmopolitan lamp transports you to a time when people strolled through town parks and walkways, enjoying the relaxed comfort of community spaces. This lamp is more than just a source of light; it’s a connection to a bygone era, making it an extraordinary addition to any outdoor living space.

Constructed with six-sided, sand-cast aluminum, the lamp’s structure is robust and visually appealing. The certified valve ensures safety and quality, and the tempered glass adds a touch of sophistication. If you want to personalize your lamp, additional glass options are available, allowing you to match it with your existing décor.

The universal finial that comes with the lamp adds a classic touch, but decorative finials are also available for those who want to add an extra flair. The option to choose between gas or electric illumination further highlights the lamp’s versatility. This ensures that the Cosmopolitan lamp can fit seamlessly into various settings and design themes.

Cosmopolitan lighting is more than a trend; it’s a lifestyle choice for those who appreciate elegance and history in their surroundings. The Cosmopolitan lamp, with its unique six-sided design and vintage appeal, embodies this concept perfectly. It’s not just a lamp but a symbol of a refined and worldly aesthetic. Incorporating Cosmopolitan lighting into your outdoor space not only enhances the ambiance but also reflects a taste for timeless beauty and sophistication. It’s a choice that resonates with those who seek to blend the charm of the past with the demands of modern living, creating an environment that’s both inviting and inspiring.

Frequently Asked Questions

Are gas lamps safe?

Yes! American Gas Lamp Works gas and electric lamps employ well-proven designs and technologies. Gas lighting actually pre-dates electric lighting by several decades, and the Welsbach mantle lighting system has been used the world over for more than a century. You should keep in mind that gas lamps do get hot and should not be placed where they can be touched by children or animals.

What types of gas do your lamps use?

Our open flickering flame gas lamps can be equipped for use with natural gas (NG) ONLY. Our Welsbach mantle gas lamps can be equipped for use with natural gas (NG) or liquid propane (LP). Our electric lamps require 120V electric.

Can open flame be used with liquid propane (LP) gas?

Our open flame gas lamps are only available when fueled by natural gas; they are not compatible with liquid propane. The only option for LP gas is our gas mantle burner, which is similar to what you see in a Coleman camping lantern. It uses mesh mantles to provide a solid, white light, like a light bulb. Mantle burners are intended to burn 24/7 and do not flicker like a flame.

How much gas do AGLW fixtures burn when operating?

The amount of gas your lamps will use depends on the type of gas and burner you’re using. Please refer to our BTUs and Gas Facts page below for gas usage along various configurations.

How do you turn a gas lamp on and off?

All AGLW gas lamps include a manual ignition valve, located in the collar of the fixture, just below the burner. To light the lamp, simply turn the valve a 1/4 turn with a flathead tool (like a screwdriver) and ignite the burner inside the lamp with a long lighter.

We recommend leaving gas lamps burning 24 hours a day to reduce wear-and-tear of the components and to keep the gas line warm, preventing any buildup of debris or insects that may effect proper gas flow.

When using an open flame burner with Natural Gas, you may add an electronic ignition system for an upcharge. This requires both Natural Gas and 110/120V electric be run to each fixture and will allow you to control the flame with a light switch or a timer.

The electronic ignition system can only be purchased from AGLW in a new lamp.


How much light do American Gas Lamp Works fixtures produce?

First, please keep in mind that open flame lamps are designed to produce a gentle, flickering light that is intended principally for ambiance rather than illumination. They are perfect for accent lighting and for creating a unique environment, but open flame lamps should not be counted on as a primary light source.

Gas mantle lamps, GasGlow® LED and electric candelabra base lamps produce bright light and can be a primary illumination source. As a rule of thumb, each gas mantle and GasGlow® LED mantle produces the equivalent light output of a 50-watt incandescent electric bulb. As a result, a quad-mantle gas lamp or GasGlow® LED would produce light equivalent to about two 100-watt incandescent bulbs.

Can wind affect gas lamp performance?

American Gas Lamp Works gas fixtures are designed to perform in normal wind conditions, but both gas mantle and open flame gas lamps can blow out in strong winds. Several factors play into the susceptibility of specific lamps to wind, including the location of the lamp on a site or building and the wind patterns in your area.

What are your lights made from?

Our lamps are custom made from commercial grade sand-cast aluminum and heavy-gauge copper. Our lamps are built to last for generations. Please visit one of our dealers to experience first-hand the difference between our foundry craftsmanship and mass-produced fixtures.

Can I return a product if I don’t like it or it doesn’t fit?

All AGLW products are custom-made specific to your order. Due to the customized nature of our products, returns are accepted for product defects only.

What is the difference between gas mantle and open flame gas lamps?

Gas mantle lamps utilize incandescent gas mantles as their source of illumination. Traditionally known as Welsbach mantles for their inventor, Carl Auer von Welsbach, gas mantles generate a bright, steady white light when heated by a flame. Gas mantle fixtures can be configured as dual-, triple-, or quad-mantle lamps, depending on your lamp size and lighting requirements. Alternatively, open flame gas lamps emit a softer, flickering glow similar to that of a candle. Open flame gas fixtures are preferable where you’d like the ambiance of old-fashioned gas light but do not need significant light output.

Are American Gas Lamp Works fixtures certified?

Yes! All AGLW lamps are certified to the most rigorous ANSI standards and carry either an ETL or UL Listing.

Are you a real American manufacturer or just an online marketer?

The American Gas Lamp Works and its predecessor, Gas-Lite Manufacturing, have been designing and manufacturing natural gas and faux gas lighting for over fifty years. Our manufacturing operations are located near Pittsburgh, PA, in the town of New Kensington, PA. Our lamps are manufactured by skilled foundrymen and craftsmen, as they have been for generations.

Where should I consider installing American Gas Lamp Works lamps?

Most gas lamps, whether gas mantle or open flame, are used to accent the exterior of a home or building. Our lamps and torches add drama and excitement to entrances, outdoor entertainment areas, walkways and drives. AGLW gas lamps can be mounted next to doorways, on walls, on posts, or on decorative piers. AGLW’s GasGlow® LED and electric candelabra lamps, which use electric energy, can be mounted almost anywhere, including the interior of homes and businesses.

Who can install my American Gas Lamp Works light fixtures?

Depending on the type of fuel you choose, gas or electric, we recommend that you coordinate installation with trained professional personnel. For AGLW gas lamps, please use a professional gas lighting specialist or an experienced local plumber. Our GasGlow® LED and electric candelabra fixtures can be installed by an electrician for dependable service. We recommend that you order your lamp early in the construction process so both the plumber and electrician are familiar with your lamp and its requirements at rough in. Most of our lamps are equipped with tempered glass to protect against thermal and physical shock.


What mounting options do you offer?

All of our lamps can be post-, pier-, or wall-mounted, and all of our mounts can be powder coated to match the finish you select for your lamp fixtures.

What kind of clearance is required for installing a gas lamp?

The minimum top clearance, from the lamp roof, should be no less than twelve (12) inches from any combustible surface. The clearance from any side should be no less than six (6) inches from any combustible surface.

What size gas line fitting is needed for the actual installation of a gas lamp?

For installations less than 200 feet in length, you will need to run a standard 3/8th inch copper line from your gas main to the base of the lamp fixture or lamp post. This feed line will then reduce to a ¼ inch copper flared line and flared fitting at the base of the post or mount.

How do I install a post for a post mount lamp?

Dig a hole in the ground that is approximately eight (8) inches wide and twenty-four (24) inches deep. Set the bottom of the post in the center of the hole. Pour concrete around the post to just below the level of the gas line access hole. Proper fitting for underground gas line will be a ¼ inch gas line through the post.

How do you turn a gas lamp on or off?

All of our gas lamps and torches are equipped with manual ignition, which is controlled via the gas valve, located in the collar of the fixture. A 1/4 turn of the valve will allow the user to open the valve and for gas to pass through. Applying direct flame to the burner inside the lamp will then ignite the flame or mantles. A 1/4 turn of the valve in the opposite direction will close the valve, causing the flame or mantles to go out.

Can American Gas Lamp Works configure my lamps to burn liquid propane (LP) gas?

All of our fixtures equipped with gas mantle burners can be configured for use with Natural Gas or Liquid Propane. Our open flame burners are compatible with Natural Gas ONLY. Please specify the type of gas you’ll be using when ordering. Operating a lamp equipped with a natural gas burner on propane can cause excessive heat and smoking and should be avoided.

Tips for Gas Lamp Maintenance

For Gas Lamps:

We recommend coordinating installation or service of gas lamps and lines with trained professional personnel. Please contact your local plumber, professional gas lighting specialist, or HVAC provider to schedule an installation or service appointment.

Professional gas specialists can often be found at retail stores that offer gas products. For example, a hearth & grill, fireplace, or pool & patio shop that sells gas grills, gas fireplaces, gas logs, gas torches, etc. Often times, these locations will have a service department with certified or experienced gas specialists who you may schedule an installation or service appointment with for your gas lamp.

To locate a specialist, please refer to a local directory.

- Gas Mantle Lamps:

Gas mantle lamps are rugged, durable fixtures that can last for generations. However, they require minor maintenance that is best performed by a professional service person. In general, we recommend the following:

  • Replace your gas mantles at least once per year, and at any time they are no longer fully intact.
  • Clean glass and remove debris twice per year. Removing debris will enhance the air flow around your mantles and improve their performance.
  • Use only authentic, hard, preformed mantles in your lamp. Hard mantles will produce more light, last longer, and retain their shape much longer than “soft” mantles at a very small additional cost.
  • Blow out the gas lines annually to ensure proper natural gas supply to your lamp.

- Open Flame Gas Lamps:

Open Flame illumination is for the discerning homeowner looking to infuse an outdoor setting with the warm, flickering light of an open gas flame. American Gas Lamp Works’ open flame gas lamps provide a dramatic ambiance to outdoor settings, entrances, and walkways. We recommend the following routine maintenance for your open flame lamp, best performed by a professional service person:

  • Clean glass and remove debris at least twice per year. Removing debris will enhance the air flow around the burner and improve its performance.
  • Clean the open flame burner tip at least twice per year. Run a piece of fine dental floss or use a wire brush to remove any debris or soot that’s settled in the burner tip.
  • Position the gas valve between 50-75% open, to where the bottom of the flame is touching the tip of the burner. Opening the valve too far can create an air pocket between the burner tip and the bottom of the flame, which can cause frequent blowouts.
  • Adjust the flame by inserting a flat head tool or screwdriver through the valve access hole in the collar of the lamp. Turn the valve slowly to adjust the height and shape of the flame.

Please note: Turning the valve too fast or too far can cause the flame to extinguish. If the flame extinguishes, turn the valve to the OFF position and following the re-lighting instructions.

It's 2 panels holding 1 big privacy screen. Can't use as 2 separate 4' panels, but works great.
Size: 2 Panel 8FT W
This 2 panel privacy screen works well. Assembly was very straight forward, with easily labeled tubes. My son and I had it together in about 10 minutes, which was probably 3 minutes of me telling him to quit playing around and hand me the parts. It feels very sturdy, not likely to fall over or anything. The material fits well, with the Velcro being very strong. Measurements are all very accurate, with all pieces attaching properly. We have a similar privacy screen at work that we have to try and stretch out because the top and bottom Velcro doesn't fit quite right... this model does not have any issues though. The material is thin and light weight, but solid black so that you can't see anything through or behind it. I definitely think it's a great deal for the money. What I think would have given it 5 stars though, is if you had 2 totally separate 4' panels instead of 2 panels with one big screen. It really wouldn't cost any extra to make it so that the screen was in 2 pieces and you could use it as 2 separate panels instead of having to use it as one big panel. It says 2 panel folding privacy screens, but it's really one big one that folds in the middle.

Versatile Room Divider With Easy Assembly and Strong Coverage
Size: 3 Panel 12FT W
I picked up this Siebwin 3-panel folding room divider mainly for privacy and room separation, and overall it works very well. Assembly is very straightforward, and the divider can be set up, taken apart, and stored without much effort. The fabric quality feels good, and the frame construction is stronger and more stable than expected. The support tubes especially feel well built and help keep the divider standing securely. One feature I really liked is the flexibility of the design. The panels can be used together as a complete divider or separated depending on the setup and available space. That makes it much more versatile for different room layouts or temporary privacy needs. The coverage is also very good, and the size matches the manufacturer’s description accurately. The fabric blocks light and background visibility well enough to provide solid privacy without feeling overly heavy. The wider feet also help improve stability compared to thinner folding dividers. Another positive detail is that everything arrived complete with no missing parts or damaged pieces, which made assembly much easier and faster. Compared to cheaper privacy screens, this one feels more durable and easier to customize depending on the situation. In terms of value for the money, it feels like a very practical and worthwhile purchase considering the size, flexibility, and build quality. Overall, a versatile and well-built room divider with easy assembly, strong privacy coverage, stable construction, complete included parts, flexible panel configuration, and excellent everyday functionality.

Stable, flexible in deployment configuration, creates true privacy and looks great.
Size: 3 Panel 12FT W
This is the second room divider panel I have installed, and there are several features about this one that I like much better than my older one. The fact that there are no gaps and that the material is thicker means you get more privacy or more hiding power, if you wish. My older divider has vertical spaces between each of the panels and the panels are half as wide as the Siebwin panels, so there are many vertical spaces. The Siebwin divider really creates privacy. Another feature that I really appreciate is that the legs are wider and stand off from the floor. On my older one the legs are flat and they're rather awkward to adjust because they create more drag on the floor. The feet on the older one also loosen if you turn them counter clockwise, so adjustments of configuration that require the feet to be moved are more complex. The older divider also must be deployed in a zig-zag fashion because he feet are not as wide, but this new one can be deployed and stable in a straight, an "N" shape or an arc. They are both the same length, but because the older one must be use in a zig-zag deployment it doesn't reach to the length of the new one. The Siebwin divider definitely costs more at $103.48, but it sports several features and advantages over the other brand, so it does a better job and is worth the extra cost.

Easy to assemble, does the job, material is shiny nylon and shows creases, minor defects, sloppy
Size: 3 Panel 12FT W, Size: 3 Panel 12FT W
The Siebwin room divider is a good idea, and for the price, it mostly delivers on the intended functionality. I ordered the 12 foot, 3-panel version mainly to hide an unfinished basement storage area that had become an eyesore. It works well for that purpose and gives the space a cleaner appearance without spending the kind of money that more decorative dividers or custom partitions cost. If you need something temporary, portable, or mainly functional, this is a viable option. There are a few limitations that became obvious during setup and use. The first thing I noticed was that the weld quality on some of the metal poles is fairly sloppy. Once the cover is installed, you do not really see it, but up close, it does not look especially refined or professional. The blackout material also is not a matte canvas style fabric as I expected. It has more of a shiny nylon appearance, and the creases are fairly visible. Being that it’s more of a nylon, I’d be hesitant to try steaming it to remove the creases. However, the creases do not matter if you are using it in a basement, dorm, or shared room, but for photography, video work, or a professional office setting, the appearance could be disappointing. The fabric is thick enough, though. It blocks visibility well enough, but strong light behind it still shows through to some extent, nothing deal-breaking. Also, my fabric appeared to be slightly defective. The hook and loop strip on one of the bottom sections was off-center and couldn't be totally attached because it was lined up with one of the legs. I originally hoped to use this as a video backdrop, but I will probably end up replacing the fabric with a proper green screen or canvas material while continuing to use the frame itself. For now, it does a good job of covering my basement junk. Assembly was actually easier than I expected and took roughly 15 to 20 minutes. The longer vertical poles are tethered together similarly to tent poles, which made setup straightforward and fairly intuitive. The shorter horizontal pieces slide and snap together to the top and bottom of the vertical assembly. After each section is assembled, the divider panels connect together with metal plates and two knurled screws (at the top and bottom), so no tools are really required. A few screws were difficult to start because paint had gotten into the threads, but once they caught, they tightened down normally. The feet install with similar knurled fasteners and help keep the divider reasonably stable. One thing to watch for during setup is the fabric orientation. There is one arrow indicator in the middle of the fabric to indicate up. However, if you need another indicator, the smaller hook and loop strip goes on the bottom while the longer strip goes on top. I realized mine was upside down right before finishing and had to redo it. I wasn't difficult to redo, despite the defect in mine. The overall design is practical and easy to move around. I do like that the panels can fold and bend into different shapes depending on the space. The widened feet help stability, although when trying to stretch the fabric tight, I noticed the poles sometimes wanted to overlap slightly at the joints. Tightening everything helped somewhat, but it still happened occasionally. The divider feels adequate for normal indoor use, though I would not expect premium durability or luxury-level fit and finish at this price point. The entire device can also be easily disabled and stored in a tote if you need it completely out of the way. It comes with assembly instructions, but even if you didn’t have them, it’s easy to build without them (save a mistake or two). In terms of value, I think the Siebwin divider mostly matches its price. Around $100 gets you a large freestanding partition with decent usability and easy assembly, but there are compromises in materials, appearance, and refinement. The defects are also off-putting, but hopefully you won't have them. Higher-end room dividers can easily cost two or three times more, so some of the tradeoffs are expected. I also noticed cheaper alternatives online, but based on the quality here, I suspect those would probably have even more issues. For practical home use, temporary privacy, hiding storage areas, or separating shared spaces, this is a good option as long as expectations stay realistic.

This room divider does the job for creating a little extra privacy and was easy enough to set up. The panels feel decent quality and the wider feet help keep it more stable than some cheaper screens I’ve tried. My only issue is that it takes up a bit more room than I expected, especially with the feet sticking out. It’s still portable and folds away nicely, but definitely measure your space first. Overall it works well for separating a room or blocking off an area temporarily. i wish it came in other colors
