Led4power.com : LD-4 CC linear drivers, ILC-0/1 illuminated tailcaps, optics, MOSX, copper DTP MCPCBs...

I did not mod anything with Carclo optics. They fitted well, although it was a tight fit. The Luxeon V is very flood under Carclo optics. Not my cup of tea. I reverted back to Nichia’s in my Emisar D4. Will be trying out Luminus SST-20 soon… From what I have read they perform well under optics.

Thanks for your input on this! I’m willing to try a Luxeon V on 10511 optics and see what I get, as it has a narrower beam.
I’m not familiarized with the Luminus, but as I’ll order from L4P, maybe I’ll try to get one to see how it looks like!

I have tried all the possible Carclo optic configurations. You just won’t get throw out of this emitter in those specific optics. The physical emitting surface is just too big! It floods beyond the TIR part. You’re better off trying the Luxeon V2, that has a smaller physical emitting surface and should yield much better optical performance.

The Luxeon V performs well in a reflector. I have a Convoy S3 single and I put swapped them in on my BLF Q8. Now it really performs!

General question about the Luxeon MZ:

Looking to do a hotrod build around the LD-B4/MZ DTP using an S2+ host, would the MZ be alright driven up to 12A CC using the 8-12A driver?

I had planned on doing a floody MZ triple, but I’ve read the MZ will handle up to 15A before output drops so now the plan is to use a 45/60deg pebbled TIR and a single MZ emitter driven with the 12A B4, simplifying the build without much loss in output. Is this a sane plan? I imagine a triple would be marginally more efficient at higher output than the single emitter if it were also driven up to 12A.

I did here:

45 degree should look good w/ pebbled tir. It will pull 15Amps in direct drive and 12A will only be a problem for your hands, not the LED :slight_smile:

Oh perfect, that quashes any reservations I had about the emitter handling that current in a small host!

I guess I should also warn you. If you do not use a high current spring or bypass it with a wire you will likely have problems with it softening up to the point it loses connection/melts.

Yeah that’s what I had figured, cheers.

The above statement confuses me. I'm about to order an KW CSLPM1.TG on ∅20mm 3030 DTP MCPCB to be fed with a heavily modified LD-29 driver, does this apply to me?

Thanks.

Cheers ^:)

That note was about LEDs which I have, but not at all possible pcbs (mostly 3x,4x,6x mosX PCBs). For example I still don't have listed SST-20 and Luxeon V2 soldered on 32mm and 34mm mosX boards for ANGIE,CUTE and ANNA optics, but I can do that on request.

So this does not apply to your case.

Hello Neven, you once wrote that can be reduced by replacing resistors of the moon mode. Can you tell me what they are and what value they must have? I have a LD-A4. Many Thanks

FET-switches and 30A drivers…

Resistor in red circle is 600Ohm (R1), resistor in green circle is 300Ohm(R2). When you select 2.5mA moonlight current in UI only 600Ohm resistor is active, when you select 5mA only 300Ohm resistor is active, and when you select 7.5mA both resistors are active.

Moonlight current can be calculated as Im1= (Vbatt-Vled)/R1, Im2=(Vbatt-Vled)/R2, Im3=Im1+Im2.

many thanks. I first order some resistors.

I have a very stupid question about these drivers. Will a moonlight mode in a driver configured for 6A last long as in a driver configured for 2A?

I want to put one of these drivers in a 14500 flashlight, and if on the one hand I want it to be bright, on the other I want it to last long in the lowest mode (just in case, you know…).

But I’m somehow confused and would appreciate some clarification! (I know this should be basic, but I’m below that :stuck_out_tongue: )
Thanks in advance!

Moonlight mode has nothing to do with main modes (resistor limited versus MOSFET regulated).

Nice!! Thanks Barkuti! I was only aware that ML could be configured for 3 different levels, but thought it would be related to the rest!
Thanks ! :smiley:

I built an X6 quad with LED4Power’s new spacer:

Thanks for all the parts Led4power. Everything arrived in good order. At first, I wasn’t completely onboard with lighted tailcaps, but they are pretty cool. They might even help me if the power goes out. One build done and more to go. Waiting on some parts.

Is the LD-B4HV going to back in stock soon? Or do you have something else planned? Also, I’m highly anticipating the release of the Subzero.
If I have something selected as being in my wishlist, will I automatically get an email once it is back in stock?

Thanks for any help.

I don't plan to stock LD-B4HV anymore. I'm not sure about automatic mail sending, so it's better to check site and and this thread occasionally.
