Thanks for the video, these are really good news about the BLF GT.
If the SBT90.2 emitter would be available in at least 80 (but preferably 85-90) CRI, and not just around 6000K, that could make even better thrower flashlights (I’d probably go for 4500K in this case).
The BLF GT as a host is really something - it is getting nice upgrades over the time.
This emitter could also justify a (let me call) ‘BLF GT Mid90’ variant with 100mm diameter reflector (instead of 120mm) and 2×3×18650 battery carrier (supporting flat top batteries out of the box) - and probably around 50-60% weight of the original BLF GT.
Been waiting for this one. About double the candela of the OG BLF GT! This emitter is really impressive and this host is what is required to fully maximize its potential.
That’s not as much as you think due to it being 3v. 27A x 4v is about 108 watts. The 70.2 version was about 8A x 15v or 120 watts.
Are you sure? I think the xhp35-hi was about 1.2-1.3Mcd and this version is about 1.8Mcd. Not really double, but definitely more, plus a bigger hot spot.
Neuh, it will be fine. It seems to use this switch:
I tested it a few years ago and it was completely fine at 16A, and probably well over that. If the electrical connections are good I see no reason to worry.
I have found the Omten switches to hold up fine til you get over 31A, then the plastic case melts and fuses the switch. (Or I’ve seen it happen, don’t know if it always will)
I agree that these currents are not suitable for small mechanical switches like these. But I’m still amazed what they still seem to handle. In the longterm you may not get away with these though…
For several of my lights that I know will easily sustain well over 30A I use Tofty switches from yesteryear. I have several of those in big lights I’ve made and they’re holding up good to high current, can be taken apart and cleaned if need be. Shame those are no longer available.
