After tuning it a bit, I managed to use the small angle optic for the B35AM LED, the dark spot in the beam is elimiated, the beam is clean now. The candela has jumped from 25kcd to 48kcd, now the B35AM version can also be called a small thrower.
Great to hear about the improved throw from B35AM after tuning! Do you happen to have an updated release estimate for DM11? I’m waiting to place a big order until after it’s available.
Also, can you tell me what the maximum regulated current is for Noctigon K1 with SBT90.2? Is it 5A or 7.5A like some of your other Linear+FET drivers? I’m working on a review and would love to include this detail.
Very nice, this is a really awesome development! Is there any chance you will still provide the option for the wide-angle optic for this or any other emitter? I know this is supposed to be a thrower, but that floody profile with the other optic was pretty nice in my opinion, it would be fun to try them both out
I have the sfs80 in a Light and I'm not convinced it is as good as a sft40. Or that it's available in other CCT's either? No upside for sfs80 if considering both, IMO.
EDIT: ive also read here IIRC that SFS80 has a hard time going over 6amps, maybe? I heard there is a failure rate somewhere in that range. Or i could be thinking of the KD P35, though those could be the same LED too.. I don't know.
I’m even more excited for this with the optic tuning, though I think I’ll still get both optics if the wider one is offered. It’s good to have options.
De-lensed it's doing better in throw, and better in lumens. De-lens, it seems to be doing as good as a Boost HX (W2) but cheaper, and using a standard 5050 footprint.
So I checked the Nichia datasheet. B35AM is 0.73mm tall. The CREE XPP is 0.75mm, NM1 and PM1 measured 0.80mm, SFT40 was 1.10mm. The round 5050 yinding came in at 0.68mm. Haven’t measured the Cree HIs but datasheet says 1.0mm.
Is your SFS80 in a Nightwatch, Mateminco, or something else?
I have a Mateminco MT35 Mini-S with SFS80 that pulls 7.2A and does 115kcd from a 43mm head (a bit smaller than a C8) and 2100 lumens from my measurements. The beam is immaculate. It also has a lower color temperature and a slightly rosy tint.
On the other hand, I have four SFT40s in one light and three of them developed black spots. The total lumen output from all four is only 7600.
