Providing a 400Ws output in a compact design, the Siros 400 S WiFi/RFS 2.1 Monolight from Broncolor is a reliable studio flash unit with Wi-Fi connectivity and a built-in RFS 2.1 receiver for wireless control and triggering. It has a 9-stop power range which is adjustable in 1/10 or full stop increments for great control over light output. The Siros S is also quite fast with a flash duration from 1/8000 - 1/1000second and a recycle time of 0.02 - 1.4 seconds depending on power settings. Additionally, the monolight has a halogen modeling light.

Built into the Siros S is a specialized Speed Mode that speeds up the charging time and flash duration to provide a fast sequence of exposures, up to 50 per second at the fastest setting. Also, the unit has a USB connection for software updates and is fan cooled for temperature control. An integrated reflector and mount are included for adding modifiers to the light.

When the Siros is connected to a Wi-Fi network, each light can be identified by a different-color LED and can be easily controlled using the bronControl app for smartphones and tablets
With the integrated Broncolor RFS 2.1 receiver, users can use the RFS 2.1 transmitter for remote control from the camera
Cut-off technology uses a microprocessor to calculate the flash duration to an output, enabling sequences with up to 50 flashes per second
Enhanced Color Temperature Control technology adapts flash voltage and duration in order to achieve a constant color temperature over the entire variation range
Individual power distribution means the unit has controllers for each lamp in order to have greater control over the flash power range
Speed mode reduces flash duration and charging time while reducing the maximum power in order to achieve a series of rapid exposures without overheating
Single rotary control for flash power output setting, a slight turn provides 1/10 stops while a "Twist" function allows for whole stops
Internal discharge when power is reduced
Grip features double-wall plastic with a special coating for durability and comfort
Aluminum stand adapter can be used with the handle to function as a built-in floor stand

Easy to sublimate. The spinners soaked in the ink colors beautifully. Easy to open for spin display too. I would purchase again. Good price and the size was correct. Quality was good for the item to be gifted.

Sub well, flimsy, no cello bags included for resellers!
Number of Items: 10
Sublimate well at 300 degrees for 60 seconds; however, they are definitely Flimsy as compared to smaller spinners and for some reason they are putting 5 to a cello bag! Which means if you are making to resell, you will need to buy cello bags!! This is the first time I've experienced this in hundreds of wind spinners purchased for sublimation. This is a big deal to me because I can't find 10x10 cello bags (and I shouldn't have to) so now my bags will not be the accurate size for the spinner as all of my others are because I sell them!

Exceptional
Size: 22, Size: 22
Great quality and price. Monitors are exceptional. Would buy again without question. Screens are quite resilient, great picture. I bought three and use them in a multi Monitor setup for my work laptop, I needed something to view wireing diagrams and scan tool information qt the same time. If your a Service Technician looking for a multi Monitor set up would strongly recommend this Monitor.
