I’m eager for a datasheet. The press release mentions a separate thermal pad, which means it has a decent chance of being usable on existing 3535 or 5050 MCPCBs.
Color: Cx=0,32, Cy=033, acc. to CIE 1931 (white)
lnom: 6 A
lmax: 6.6 A
Phiv @ Inom pmin: 1400 lm
Luminance: >200 cd/mm²
Rth JS real typ.: 1.8 K/W
Rth JS el typ.: 1.3 K/W
Vf typ.: 3.35 V
Dimensions: 4 x 4 x 0,73
Looking at these, 1,400 lm, if achieved at 6A 3.35V, comes to 70 lm/W.
The package is 4 x 4mm thermally-enhanced ceramic, with an electrically isolated bottom pad.
May beat KW CSLPM1.TG. Which handles 6A in pulses (up to 0.1s) and 5A continuously. Has Vf of over 3.5V. But the top bin does c.a. 1800-2000 lm at 6A. The minimum flux of the lowest bin at 6A is near 1300 lm. Thermal resistance real 2.6, electrical - don’t bother to calculate.
And has a non-square die.
ADDED: For a 2 mm² Lambertian emitter, 1400 lm is 222 cd/mm².
That sounds amazing, 200cd/mm2 stock should be like 300+ once we overdrive it on DTP MCPCBs
Can’t wait, this will be a serious upgrade over the black flat, unlike the CSLNM1.TG which is only a slight improvement.
However, it will be many months or several years before we can actually get some of these LEDs.
The CSLNM1 isn’t even available yet in multiples less than 1000
Regardless, laser phosphor is still a better option for ultimate throw.
This LED will be good for normal LED flashlights.
When faced with the need to use a 5050 reflector centering ring over a 3535 emitter, I've succeeded by carefully glueing the centering ring over the emitter board. This glue (for example) works well and any excess is easily cleaned with alcohol.
