1/10 or full-stop power intervals; built-in RFS 2.1 receiver
1/8000 to 1/500 second flash duration
0.04 to 2.9 second recycle time
Flash Output. The Broncolor Siros 800 S WiFi / RFS 2.1 Monolight offers a 800Ws maximum output, with 9 stops of adjustment in 1/10 or 1-stop increments. You can adjust flash durations from 1/8000 to 1/500 second, and recycle times range from 0.04 to 2.9 depending on power settings. All of this in a compact, reasonably lightweight package.
Built-In RFS 2.1 Receiver. The integrated RFS 2.1 receiver lets you use the Siros 800 S in conjunction with RFS 2.1 transmitter units for remote control from the camera.
Cut-Off Technology. The Siros 800 S will calculate the shortest or longest flash duration for a given output, and then use that information to enable rapid flash sequences at up to fifty flashes per second.
Constant Color Temperature. This monolight maintains color temperature over its entire power range at all outputs, but you have the option to change it in calibrated +/- 200 K steps at constant power.
Speed Mode. A speed mode reduces flash duration and charging times by up to 50% and maximum power output by up to 25% to prevent the light from overheating when you’re shooting a series of rapid exposures. A cooling fan provides a little extra help during long flash series.
Halogen Modeling Light. The built-in halogen modeling light provides up to 300 W of incandescent light. It has two power settings: full and proportional to flash output.
Optional UV Attachment Available. If you’d like to use this flash for scientific, forensic, or special-effects photography, we offer the Broncolor UV Attachment as a separate rental item. The UV Attachment only transmits ultraviolet light, filtering out all over wavelengths.
