This particular light source would be continuous tungsten light set up, so there would be no specifications for it regarding flash duration, recycle time or triggering method. The light source would simply turn on and off with an inline switch on the power cord. Those types of specifications are specific to strobe lighting. Please see the link for reference to a strobe kit: http://bhpho.to/1HDmFVHThis strobe system would have a recycle time of 3 seconds at full power, a flash duration of 1/1000 at full power and 1/1500 at minimum power. It can be triggered via the include sync cord connected to a camera with a sync terminal or you may use an option wireless trigger like the following: http://bhpho.to/1riehZv

The Impact White Translucent Umbrella (33") is designed for a light to be shot through it, so pointing the umbrella directly at the subject works best in most situations.

The bulb spec is 3200k. I havent done anything to verify this but the auto white balance on the camera yields decent color accuracy. Good enough for web publishing.Hope this is helpful.
