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.
It is expensive so not many people are buying it and so it is not discussed as much as, say, the FT03 with this led (that is: once it starts being shipped)
