Thanks, so as i understand the driver on the 1. link is good for this led, and will drive the led at 100%, but i need a good flashlight host for culling, i am planing to use uniquefire t20 host, i think that is a good housing for cooling.
The flashlight says 1200 Lumens which is at least 10W. What is not clear is what voltage the LED array is using and the purpose of your external driver and choice of battery voltage 2x3V or 1x3.7 or external?
