Long story short, all my flashlights have given way to a commercial innovation I am looking where these will need to burn everyday/all day. Efficiency is paramount. I am getting tired of looking at CREE specs and having to run the numbers myself to based on their graphs enough though they have the data. They like to rate them at say 190lm/W and spec them as a 15W LED, only to find out 190lm is at 1W, and 15W is like 90lm/W. They also seem to have quite an inflated price but I have not looked at competitors yet.


Anyone doing real testing to see who else is in the game?


Also, I am curious if most buy these LEDs on a chip with wire pads or what? I have not torn into my flashlights too much but I am pretty curious what they are toying with for a driver in there? 1mode, 3 mode, 5 mode, etc. What are they doing in there? Is there an LED driver IC they are using with all the functions built in?
