Bright, with great diffuser
Size: 16.4ft
This is a nice, flexible light with a good diffuser. The tape is sticky, so make sure you want this to be permanent, because it's likely to damage wall paint when removed. Lot's of color, pattern, and dynamic light options with the software. My last Govee light strip had the green LEDs burn out after a year, hopefully that's not the case here. I will update this review if that happens. These are pretty pricey, so hopefully they're durable!

Awesome lights just know that they are neon colored and very bright!
Size: 9.8ft
These lights were very easy to install. Very much more flexible than rope lights or even desk lights. They look awesome on my cabinets if I do say so myself….. also know that it wherever you put them is where they’re going to stay… for eternity. Adhesive is so strong that when I had to remove one, I had to use a knife and cut the adhesive off of the actual light itself and leave the adhesive behind or it will tear all the paint off of my wall. It’s a good thing that they’re very strong adhesive wise. Just make sure that you know exactly where you’re putting it and that you have measured properly and if you’re going to cut it, make sure that you do that before you start putting it up. Also, a big deal is that these are neon colored and very bright! If you are trying to match something like dream view, for instance (I did) they will not match with the other lights at all not even close. They don’t even match the desk lights that you see in the video along my countertops. I have to turn the brightness down or it overpower the entire kitchen and other lights.

Super Bright and Even – These LED Strips Are a Game-Changer
Size: 9.8ft
I’ve been using the Govee COB LED Strip Light Pro for a while now, and honestly, they’re unlike any other LED strips I’ve tried. They’re ultra bright—so much that they actually feel like regular overhead room lighting. That’s a big deal if you’re trying to light up a whole wall or create even, direct lighting without harsh spots. I was really impressed by how even and clean the light spread is; there are no visible dots or hotspots, which makes them perfect for wall-washing or under-cabinet setups where you want that smooth glow. One thing I noticed is that the adhesive is decent, but not super strong. At first, I wasn’t thrilled, but then I realized it’s kind of a good thing—especially if you ever want to remove or reposition them. Since the tape isn’t overly aggressive, it won’t rip up your walls or leave a nasty residue. That’s a win for renters or anyone who likes to switch things up. The packaging felt premium, and the colors pop—whether I’m using them for ambient vibes or cranking them up for brightness. The Govee app is easy to use, and the built-in scenes with smooth animations make it fun to switch up the mood quickly. Now, here’s the real talk: these lights are expensive, no doubt. But if brightness is your top priority, I haven’t found anything better on the market. They really do stand out for being strong enough to replace traditional lighting in certain setups. The color accuracy is good overall, but when I use DreamView, I notice it’s not perfect—mainly because you can only set 6 zones per strip. That limits how detailed the color mapping can get, especially on longer runs. So if you’re going for ultra-precise RGB sync, it’s not flawless. But for everyday brightness and evenness? These are hands-down the best I’ve used.

Awesome set of lights!
Size: 16.4ft
Great example of you get what you pay for! These lights actually stay stuck where they should unlike cheaper versions that peel off over time. The remote is very easy to control and there is a massive variety of colors and moods to choose from - something for everyone! Adds just the right mood for whatever you’re looking for.

Cost too high
Size: 9.8ft
Bulky and heavy plug/wiring. Control ‘remote’ is attached to wiring/plug. The strip itself is heavy and does not stick well on ceiling nor walls. Would be best used on shelves or floors. Not worth the money. It is a basic strip of lights with a thick coating over lights.
