Here’s my next project built around 32mm 3xXH-P 50.3 5000K 9050 led engine with Cute 3 SS optics and Convoy L6 driver.
Nifty Fifty Headlight.
It’s gonna be massive and it’s gonna be brutal (well it would be if I had a better driver option). Designed and machined by me. Some milling is still missing but the major part is done.
What’s missing is a mount for the light and the battery pack both attached on a headband. The battery pack will be built around 2S 21700 EVE 58E and 2A usbc balancing charger and will also include a mechanical switch and a battery indicator. Both will be printed on a 3D resin printer
I’ll definitely try to squeeze a 5050 in there just for $%^&* and giggles, if the opening is big enough or won’t take too much effort to open it up to 7070 I’ll do that too but I’m guessing the beam pattern will be too far compromised.
Might also fit the M21H . That would save a lot of work.
How long does it take to become too hot to hold? I build a light with 6 xhp50, it has a lot more aluminum under the mcpcbs, a lot more surface area, but its active cooling kicks in after like 2-3 min on full power. I used 55C thermal switch within few inches of each mcpcb, I also used 2x 35mm triple stars, and same cute optics.
Awesome build so far, looking forward to updates, particularly the body and electrical connections- I’ve a spare body tube and tail cap for my Emisar DW4 I have (long term) plans on turning into a remote-battery headlamp, so will be interested to see how you connect up yours.
