Since they are rectangular instead of square, maybe a headlamp or bike lamp using a wide angle lens? The beam would then still be super tight in vertical orientation and super wide horizontal. :sunglasses:
They are not really very rectangular, it’s pretty close to square.
In a reflector it still makes a round spot, so have anything noticeably wider than taller you would need a lens, and even then it’s still pretty square.
Yes, but if you do use a wide angle lens meant for bike lights and such, and orient the slightly rectangular die in the same orientation, it should make an even more interesting beam shape than the lens would make with a truly square die. Add to that the fact of this particular die being such high intensity for throw, and you get something very special indeed!
I changed the 2mm2 white flat (so not the throwier 1mm2 version that has a bit too low output I think for this light) in my mini-GT for a dedomed XP-G2 3D because of the much better tint, I do not like the very cool tint. It costed me just 15kcd.
The XP-L Hi comes in many tints but I was unfortunate to never have found a tint that was really great.
The GT mini has a FET 4.5A driver. Does this mean it’s direct drive or constant current? I want to use this led but don’t know if the stock driver will work.
I don’t know where you read that the driver outputs “4.5A” but the whole point of a FET is that it will pull basically all the current the battery can provide (minus the resistance of the circuit in the host and driver).
Some ppl are saying you can DD this led (1mm) and some are saying you can’t. I’m really confused. If I use a keeppower protected 3500mah in a GT mini how much current will it draw?
for DD the current with full cell needs to be below 4.5A, so some older cells like NCR18650B with PCB may do only 4.5A when full
also you may try to solder simply a 1W 47mOhms resistor on each contact on the MCPCB to get the current limited
