Contacted lumintop, asked to buy BLF GT70 mcpcb. I got a response “how many” and when I said “one, but I’d start a thread on BLF to reach a higher number if you tell me how many would make it worth your while”.
That got me ignored, so here we are.
Between my quickly antiquated BLF GT, and my SD75 with output way underspec that also destroys batteries with parasitic drain, Lumintop is almost on my nope list.
Rant over…if anyone has a MCPCB they’d like to sell, or can point me to a substitute, I’d appreciate it.
I haven’t seen anyone try it, but if it’s not wide enough, maybe I’ll jb weld over the solder joints instead of capton tape.
Now that I have better throwers, I’d really like a lot more output. Might even go w/ xhp70. I don’t have one and hear too much about tint shift so maybe not. High CRI might help me distinguish where to land my boat.
I want a medium range (100 to 300m) light with a big hotspot and a lots of lumens, but turbo can be 10 seconds on, 20 seconds off duty cycle for my use case, and really just 2-10 minutes total.
I think I’ve read the original mcpcb is a bit over 2mm. Seems like an oring up front or spacer on the pcb could resolve fit issues, but maybe not focus? I have copper sheet, but I think adding that under pcb would make too many low thermal interfaces for my desired output.
