does anyone know how bright the xenons are? ie 3000k or 600k etc.

 

The Kelvin scale indicates what is known as color temperature. The higher the number, the more blue the light, the lower the number, the more amber the light. Common incandescent bulbs are around 2400K. Color corrected quartz bulbs are around 3200-3400K. Standard daylight is typically 5000-5500K. The light of a clear blue sky without the sun (as in a north facing window or east facing window in the PM) is as high as 9000K. Very blue.

Brightness is typically measured in candlepower, lumens and watts(actually a power measurement, not necessarily a brightness measurement, but occasionally useful). I do not know how bright the Xenons are, but I believe lights of this type throw more light per watt of energy than conventional halogen lamps.

 

All that's true but I think they were looking for the Temp. of the bulbs. I believe they're 4300K.
