Thanks, that’s what I was thinking so the light could more usable.
I would compare the light to a Maglite, which I’ve seen modded with 3x xhp50 / 5000lm

But I also see it gets real hot, 225 degrees in 15min. What you got today - #9595 by Terry_Oregon
.
Also there’s no 5050 16mm mcpcb with pads to mount the mosfet, so LD-B4HV can be used only with 20mm mcpcb, correct?

Yes, LD-B4(HV) can be used with 20mm boards, on 16mm there is not enough space for anything other than LED.

When can we expect to start seeing these LEDs?
Probably in the next 4-12 months, they are not in production yet.

BLF Q8 4040/5050 copper DTP boards arrived:
I will send two to djozz to check if everything is ok.
Also, 20mm copper DTP 3535 board(70um copper,gold plated top,nickel plated bottom):
Price is: 1,17€/pc , I will list it on web tomorrow (contact for larger quantity discounts).

I can check the Q8 boards but I assume they are ok, they look good. I will check the Q8 board with Luxeon V’s, but I have only two left, could you send 2 Luxeon V leds with the boards? (I will pay for them).
I do not own SST40 leds but I can check the 5050 pads with XM-L2 leds if that is ok with you, for checking the function of the board that should be sufficient. If not I can order some SST40 leds but that will take a while.

Wow, that’s fast. I expected it that it would be a while before you had the Q8 boards ready. How soon can we expect the triple 4040 32mm boards?

@djozz
I already packed 2 boards and 4 L1V1s. 5050 checking is not necessary, if 4040 are good, 5050 will be too.

That’s some fast turnaround time. I guess I’ll be making another order in a month or so.

Very nice looking MCPCB’s, looking forward to trying the Q8 with Luxeon V’s or one of my favorite the XM-L2 7A3 CRI90.
@LED4Power , have you thought about doing Nichia 144AM MCPCBs?
I would love a 20mm Nichia 144AM MCPCB.

I think BLF member clemence has those?
No, not a 20mm version yet.

Q8 pcb is out of stock until djozz checks if it's ok.

Also ordered one reel of Samsung LH351D 4000K 90CRI few days ago, they should be available in ~3 weeks.
