I just so recently did a build using a CULPM1.TG (HX Boost) with an 8 Amp driver (the Convoy model for such emitter - link). Using a PLB 26650 / 5000 mAh cell (measured 14.4 mOhms w/ YR1030 Battery Tester) I got 24,700 Lux (converted to ~ 800 lm) on turn on. The beam is an angry blue to violet. Tailcap draw is 7.89 Amps.
Didn’t want to push this further, I toned down the amps by using a higher IR cell - Sofirn’s 5500 mAh at 45.7 mOhms IR. Tailcap reading at 6.16 Amps and 32,060 Lux output. The beam is rather cool white but not angry. The Candelas clearly show the LED was overdriven: 41 kCd at 8 A vs. 71 kCd at 6 A.
Can’t figure what goes. Should be able to handle the 8 amps and produce some 1200 (expected) lumens. As is (w/ the Sofirn cell), about 1050 lm; bearing that I didn’t calibrate my lightbox with Maukka lights but my own which do correlate with some of the published data on the forum.
This was a test run as I planned to reflow the HX Osrams to a Sofirn SD01, a triple w/ regulated output (so I’ve been told by Barry).
I don’t see the CULPM1 on their AE store. Link to what you bought? And I’ve always been suspicious of the white flats they had. They have an extra weird grey printing on the surrounding silicone that isn’t on any others I’ve seen.
They could have been real Osram preproduction versions or rejects that got leaked into the market, but who knows.
Simon is the only source that I personally know of that has trustworthy HX available that’s on the warmest end of the CCT binning available. Maybe Led4Power when he reopens in a few days.
Found them at Mouser.
The mouser batch is a much lower flux bin than Convoys
I think it depends heavily on how hard they are driven. I can say my personal experience is that the 4040 pad versions are warmer (looks like ~5500K) and have a higher duv/more green tint than the 3030 versions, of which all of mine have been 6000K+ and very rosy.
You can put the 3030 CSLNM1 on a 3535 pad but it’s a tight enough fit that tolerances means it may not work on some 3535 pads. I would assume though it would either fit all pads on the same board or none at all, i don’t think it would be a case of it fitting only some.
It’s also a bit fiddly to align them to the pad which will slow you down when doing multiple reflows at the same time so i consider anyone who can do many at a time to be a superstar
This HHL532.TG has nearly the same Vf as XP-l hi until 3 amp. So it could be able to simply swap with XP-l hi in some light with buck driver for XP-l, like in Convoy L2, L4 for those who prefer constant output like me. Getting around 800 lumen at 2.8-3amp is nice. Interesting!
