Luminus SFT-20-W

No problem at all and (spoiler alert) after my first experience with this LED, 10 minutes ago, I think it was not worth your time testing it anyway! :wink:

Could have been an option, because I quickly put it in the planned host and the hotspot (and the beam profile as a whole) where horrible. The reason I state “Could have been an option”, is that I’m already convinced This LED is not worth investing more time in, but more on that later on.

Yeah, also spotted that already and was planning on reflowing/correcting that. (But probably not anymore.)

But let’s get to my first experience a few moments ago:

I placed it in the planned host (Mateminco X6, powered by a 18650), paired it with a Convoy 17mm 8A buck driver out of caution, and not immediately a 10A buck driver, in case that the 10A stated by KD would be to optimistic.

First of all: on the lower outputs it’s HORRIBLY green! That is obviously nothing new for (quite a few) Luminus LEDs, but I think that I’ve personally not seen it this bad so far. The driver was/is still in the standard/stock 1 group (so 0.1%, 1%, 10%, 35%, 100% + a few blinkies). At the 35% mode it finally turns into a decent white light.

But then the 100% mode, on the 8A(!) buck driver: it gives white light… for probably just over 1 second and then turns REALLY ANGRY BLUE!

There is enough Arctic MX-4, so heat transfer shouldn’t be the problem.

So I think it’s fair to say that there is probably no way it can ever handle the claimed 10A and even the 8A from the Convoy buck driver is already overkill. (Unless I have an extremely bad sample!)

I could probably pair it (safely) with a 5A buck driver, but given all the extra work in having to center the LES, it basicly isn’t worth it I think.

So unfortunately a couple of (way) too expensive and unusable LEDs… :upside_down_face:
