led4power:
It is CSLNM1.TG, I will put them on sale in few hours. Better be fast because next batch could be in 2-3months, this is new LED so production is started just recently.
Vf is insanely low for 1mm2 die LED, 3.18V@3A and 3.40V @5A , 25C.
BLF member luminarium iaculator already tested this LED in real life vs best old XP-G2 S4 - it beats XP-G2 in throw, that’s for sure.
I presume he just drove the XPG2 at the same levels for 1:1 throw comparison. I wonder how the XPG2 would fare driving it up incrementally until it hit its limit at about 6 amps? Or to just cut to the chase, compare them when both are driven up.
Btw while on that topic do ya know about what’s the amp limit on this LED?

It comes on a copper DTP MCPCB correct?
Is it sold out already or am I too early?

I assume it is a bare led, and I have not seen it listed yet.

Well, in his pic above, led4power shows it on one of his L4P boards, so maybe it will be available already reflowed. I looked at his site and didn’t see it either.

Yeah it would be great if I can buy them already reflowed nicely

The led is listed at l4p’s site, on 16mm and 20mm board. I hope that bare leds will be sold too?

Bare,16mm,20mm for now, some triples/quad PCBs later.

And quads? Would be interesting in Emisar D4.
EDIT: I see they are planned already.

Shoot, I ordered too soon before the bare led was listed. Neven, could you change my order to 6 bare leds, no boards (should be about the same total price), or should I do a request on your website?

What 5A 3V constant current driver options are there for e-switch lights?
14*AMC7135 doesn’t sound appealing. More like appalling really.

Numbers he told me are next (host is 1503 Uniquefire):
XP-G2 S4 (old ones with small die) : 245kcd @4.7A
CSLMN1: 315kcd @5.3A

Ok, I will ship you 6 bare LEDs instead.
Ordered 5! Sending them to Vinh.
So hypothetically, how would this compare to the Black Flat? From my understanding it’s 1000 lumens vs 800 lumens with same die area?

Blackie did 937 lm on a bench, this does 980 on a different setup. So it may be actually worse, but more likely it’s a bit better. Don’t expect big gains though.
That’s too bad. Can’t wait for the Boost though.

Just bought 5 of them
Looking forward to seeing the CULPM1.TG (Boost HX) in the future!
Thanks, Ledpower.
Looks linearly roughly about a 14% more candela efficient LED per amp.

Neven, i don’t see any mention of colour temperature of this TG.
[edit]ordered 3 pcs anyway.

Probably 6500K as usual, just like the black flat.
You can check the datasheet for the cct and that kinda stuff.
