Please email us at techsales@opticsplanet.com regarding the problem you are having with the SureFire M600DF Ultra Scout Light.
The manufacturer only states the lumen output for the SureFire M600DF Ultra Scout Light Dual Fuel LED Weapon Light. For the Candela rating of the SureFire M600DF Ultra Scout Light Dual Fuel LED Weapon Light I recommend contacting SureFire.
The SureFire M600DF Ultra Scout Light Dual Fuel LED Weapon Light will work with SureFire Scout/Insight SR09-D-IT Light + Laser Pressure Pad but you will need a compatible tail cap. The tail cap located at the link below should work.

The Surefire M640 DF is sold on its own, you would have to buy a switch separately.
