Involvement:General (knows how to use it) - Ownership:more than 1 month
First the Light output of 320LM is measured at 700mAmp`s. You can drive it much higher 3Amp`s or more to get more Lumens
I used this LED many times in my Projects and have no doubt to drive it unil 4.5 A
The color is cool blue but yuo get a few "extra lumens"
Good built quality well centered and welded on it`s place
the heat dissapacy could be better with a copper base instead of aluminium.
Nice LED, a bit cool but far away from blue.
If you plan to drive the LED with more than 4 Amp`s make sure to heatsink as best as you can!!!
Best result`s with Driver SKU: 127684 and a Trustfire "Flamed" 18650 Battery
