Simon Mao will put one in a L21A with an 8 A driver soon and share the results!
Eager to know the results, if they are any good i will certainly buy some parts
That size reflector should see close to 450kcd max with this emitter according to my estimates… we’ll see what others get. I don’t think the 8A driver actually pushes 8A. If course without an output test done on these yet it’s hard to say how much is here on the table just with drive current. Also, I’m not sure how much time if any he put into optimizing focus. Does anyone else have experience with the 4040 gaskets? Are they as thick as the 3030s?
What’s the difference between CSLPM1 and CULPM1? Both are 2mm size emitters right?
I wonder if the current batch of M21A now accepts the slightly wider 21700 batteries (eg. Lii-40A and others). The earlier M21A won’t fit the Lii-40A (or Lishen 21700)
Exactly. The idea is that the larger footprint allows higher currents due to better heatsinking.
Osram’s datasheet says 6A, but since when did we use to stick with specs from datasheets?
We run cree LED’S on currents not even mentioned by Cree
I’m curious what the difference will be, since the surface area is 77,77% larger. (16mm instead of 9)
That means it can be abused a bit more (run higher currents) or sustain longer (better thermal dissipation/better performance)
I wonder if the rather small amount of more efficiency on CULNM1.TG / CULPM1.TG will be advantageous if used in a multiemitter array, e.g. underneath a quad optic. I hope to seeing some flashlights using CULNM1.TG underneath a Carclo 10621 optic anytime soon. Maybe Hank (KR4/D4v2) or Sofirn (IF25A) can offer something like this. Acebeam is using CSLNM1.TG (White Flat 1) in their TK16/TK18 lights.
I’d guess using 4040 LED’s might not be worth it on a smaller build since you may not be able to max them out anyways. I ran this one w/ FET enabled using a VTC6, yolo.
3x Osram Red Flat (CSLNM1.23)
MTN triple 3030 board
lume1 buckboost driver
lume1 RGB aux board
Wow, niiiiice! :THUMBS-UP: :LOVE: I got to have one of these! :)) Maybe I should ask Hank to offer his Emisar D4v2 using a triple board with KR CSLNM1.23 or KW CSLNM1.TG using 10507 or a quad board using 10621 along with his 7.5A constant current driver (w/o direct drive). That would be a perfect add on to his custom builds using SST20-DR.
