So 2mm2. About as small as the SST-20, but domeless.

If only it had much lower thermal resistance and was cheaper, because as it stands, this one costs a lot more than 2$US, even in bulk lmao.

So, fogofwar will test the LED next week:
“Ah I haven’t had time this week. I’ll try next week”

I’m patient, but hopeful Smile

Anyway, I have an idea about the other LED. We won’t be doing a group buy for it, but after the Rayten GB ends, I think we’ll be able to do something else Silly

Yeah, but I’m not going to get this one, especially not for the GB.

It would increase prices considerably Silly

You misinterpreted me a bit. I just contacted the guy and will get samples shipped to me next week. I’m quite slow so it’s probably at least another week or two before any test results. Right now, I don’t have any extra MCPCBs, drivers, or hosts so I need to get those as well.

I think the lumens are rated at 1A.

Great work Bluesword, can’t believe you’re actually getting an LED built.
I’ll buy 10 just as a token to support what you’re doing.

@Marc E, thank you.

@fogofwar, very nice.

Is it an impression or do the dies look way closer than in the datasheet?

I’m not sure on closer but the cross does have phosphor which should help.

@llk, you have been added.

We’re getting a decent number of pcs.

We should have enough demand in a few weeks so that we can start getting the orders in, especially since fogofwar has the LED and has now gotten an appropriate host for testing an beam profile edge case scenario.

If it came warm (3000K or less) I would be in. This is not my taste….but it’s still amazing that you’re doing it BlueSwordM. Smile

Yeah, I guess.
I just want to see the beam profile so we can get this up to Sonic speeeed.

If everything goes well in fact, I might either get a WW white version and give some LED suggestions to a manufacturer or do something a bit different Smile

Anyway, I guess the GB will start anyway, since fogowar hasn’t been able to test the LEDs.

I’ll ask for a CW sample with it soldered to an MCPCB to make for easy testing Big Smile
