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
https://asflashlights.com/led-upgrades-for-maglite/84-5000-lumen-2-d-siz...

But I also see it gets real hot, 225 degrees in 15min. http://budgetlightforum.com/comment/1307634#comment-1307634

.
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.

Yes, definitely! A copper pcb for Osram 3030 LEDs make smore sense anyhow because it can be used for more types of LEDs (Osram Square, SSL etc.).


When can we expect to start seeing these LEDs?

Current Collection: BTU: Shocker (3 x SST-40 @ 8A)Lumintop: BLF GT70 (CW Sliced), BLF GTmini; Solarforce: 2 x L2P (XM-L2 U3 2C @ 4A), MPP-1 (XP-L HI @ 6A), MPP-3 (3 x XM-L2 U2 2C @ 12A), M6 (Nichia 319A @ 6A), M8 (Cree XHP-50.2 @ 9A), 9x (9 x XM-L2 U2 1A @ 2A)

Coming Soon: Lumintop: BLF GT4; Sofirn: BLF-LT1;

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.

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

I see in few BLF threads people expressed need for BLF GT XHP70 DTP MCPCB. I can make them,just like BLF Q8 PCB, is there bigger interest(100pcs+)?

If yes,I can make a batch, available in ~1month.

If there is any other interesting MCPCB, I can also consider it.

As seen in his video, (at 1.45 minute) vestureofblood has used a prototype of such a board (with TA logo) in his XHP70.2 GT, the idea I think is that Lumintop at some point will come up with either a XHP70.2 GT or the loose board (and driver). There is no mention of a timeline for when things are happening but the question I guess is if there is a market for two sources for such a board. (perhaps you can contact Texas_Ace about what is going on) .

For me personally I’d be really happy if in a month or so there is a board ready, I have a driver and a led, I’m just waiting for a board now, and I’d be surprised if a Lumintop board will be ready a month from now.

Edit: Btw, I got the Q8 boards and leds in, just waiting for some time to swap them in a Q8 and check the fit and numbers.

My family was gentle on me today and allowed some time to try the led4power Q8 board in a Q8. I posted it in the WDYMT thread. In short, it works fine and the Q8 with Luxeon V leds rocks!

So I’m not up to date on the latest emitters, especially non cree emitters. There may be a better option coming soon. Seemed to be the case as I read some of the previous comments a day or two ago. I’m wondering however, if there would be enough interest in a 16mm board for the OSRAM black flat.

Thanks djozz! That was quick, I sent boards 4 days ago.

I will update Q8 PCB listing today.

I will make 16mm OSRAM mosX gen2 PCB (~4times lower thermal resistance compared to mosX), difference in output compared to copper DTP should be ~1.5 - 2% based on some calculations.

Triple/quad? This is the only powerfull led that may help carclo 10mm optics work the way it was developed for.

I have 3XP mosX, it should be good for testing.
