Yes, I aggree. But how much heat are we looking to rid ourselves of?

10 watts and its efficiency score equals 90 lumens per watt.

These are also used in small tactical flashlights which run off a single 18650 lithium ion cell. These flashlights all all aluminum so the entire body is used as a heat sink. Runtime only being 1.5 hours tops.

I'm thinking about using a 6 volt lantern style flashlight. Hmmmm...........perhaps an aluminum reflector assembly that is in thermal contact with the LED Star Mount?

I still haven't found the answer to the question:

Is an LED driver only required when using higher voltage?
