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

Pity that Angie wont fit cute-4 boards if youll make them…

I will make both pcbs.

Excited for these new PCB’s. Really enjoying my M2 quad w/ Luxeon V

Nice! I guess I’ll make another order once you have them available.

That anna makes me trigger happy :heart_eyes:
Especially if Sofirn makes 21700 C8F that accepts MCPCB for it. I can already see 7 Vees with 30T :innocent:

Decided that I need to upgrade my convoy L2.
So just ordered a luxeon V on a MosDTP board together with a LD-B4 (set at 9A) and the ILC-1.

To be honest I forgot the check if the ILC-1 will fit in a L2 (first ‘new’ version, 17mm driver) but should fit right? :smiley:
Otherwise I will be ordering a S2…

Could you please check brass retaining ring diameter on L2 tailcap? If it's ~19mm, then inner tailcap diameter should be ~18mm, which is the same as C8,S2... and ILC-1 should fit.

The switch board diameter is the same as the convoy C8. The dimensions of the retaining ring are not exactly the same, it’s 20.7mm on the L2 versus 18.8 on the C8.
So it’s a little bit bigger but I think that shouldn’t be a huge problem.

It’s the height that will be a problem not the diameter. You can rig up something to add length to either side of the switch though. You will just need to be a bit more creative since it’s lighted. The washer from the L2 fwd switch is 2-3x as thick as the usual one which the ilc1 replaces

I’ve noticed. Luckily I have a 3d printer so should be able to make something to fix it.

Added ILC-1 kit (called ILC-1B): ILC-1B kit

Price is more budget friendly than ILC-1: 6,97€

No brass ring needed, but top pcb should be glued with epoxy to prevent pcb/wires twisting during installation.

PCBs have 17mm diameter, so ILC-1B should fit in more lights.

It would be especially interesting if you offered them with centring rings…

There are new OSRAM leds that should replace that led and black flat, so I think it's a good idea to wait for tests.

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.).

Considering LD-B4HV driver for 2S, where can I see a complete detailed description of the UI?

UI is the same as LD-A4/B4, please check datasheet for those drivers: https://led4power.com/downloads/

Thanks, so this driver also has capability to choose between current regulated or direct-driven high mode?

Yes.

Awesome.

I need some advise for the LD-B4HV, I’m not really too technical on drivers, I can install them but don’t really know what makes them tick, therefore I have to ask some questions to make sure it will work for my application, so first I’ll give an overview about the light an my plan:

I’m upgrading a LedLenser, converting from 3C to Li-ion’s, I plan to run an XHP50.2 with 2*26650 in series (might end up using 2*21700) I have a solid brass pill with threaded connections to the head so I think it will shed heat fairly well, the driver wil be secured by retaining ring.

However the switch may be the weak link, it has a side switch (not an e-switch) but I’m not sure it’s current rating. I have a feeling it may be pretty good so I’m thinking the 4A-6A version would work. The switch works like a reverse clicky, once its fully clicked on you can do half presses (which currently only flashes the led off and on, since it’s single mode)

I’ve been looking at drivers from mtn, the choices (I thought) were a QLITE/zener mod or FET/zener mod, however after sort of deciding on the QLITE I was informed it would be better to use the MTN-MAXlp HP Buck Driver (1A-5.5A)

I was told the reason is the QLITE is a linear driver and since I’m using larger cells the difference between the input and output voltages would be too great.

I really like many of the features of this LD-B4HV, especially the adjustable current and CC/DD Enable/Disable for high. So now the questions:

  • Since this is also a linear driver, will it work good for my purpose, or will the voltage difference be too great since I’m not using smaller cells?
  • Is this also a zener mod?
  • Mode order set to Backward means It will start up on 100%?
