Hmmmm… So when will these be available?

Same firmware and features?

Neven, do you see any chance to offer Carclo 10507 triple and 10621 quad optics in your shop?

Unfortunately, the 10507 seems sold out but was offered for a very reasonable price in the past.

Hvala vam!

Cheers, Thomas

What about offering different sizes of drivers? currently i only see the 17mm in three varieties

That looks like it, indeed.

LD-A4-20 (20mm version) is available:

I must have missed that one.
Actually i was looking for a 22mm driver, otherwise i’ll just have to order an adapter retaining ring

Received my order today, i just ordered thursday, so shipping is really fast.
My order came well packed and in a sealed ESD bag, the quality of the items and packaging of LED4POWER is top notch!

I will keep you posted with results

Those Aluramic boards are beautiful, and those bronze springs look like they’ll do nicely! All-around great upgrades.

Hi Neven,

would you be willing and able to sell the mosX material as round blanks? This would be great for some highly integrated driver/MCPCB combos….

When lh351d 4000k will be available?

And how about 14mm DTP MCPCB’s?

mosX material can’t be used for DIY because there is layer of titanium above ceramic on which copper is electroplated. You can’t etch titanium with anything that’s not terribly dangerous for DIY.

I tried to etch it with standard FeCl3 solution and it does remove copper layer but titanium layer stays.

My manufacturer said that they have problems with sourcing this material so batch of 16/20mm mosX/aluramic boards for IR LEDs is probably my last of this kind.

 

Too bad, but thanks.

Does the supply shortage mean the “standard” MOSLED will be gone too?

ehh, just noticed my mistake… I meant the MOSLED, not the mosX/aluramic. I’ve been able to etch those with FeCl3 after removing the solder mask in select spots, although the bare alu needs to be masked off too. (It goes faster than the copper!)

Demand for that is probably too low.

I have not seen one proper 14mm DTP MCPCB available anywhere. Maybe you should consider making 100 or so. Even if they are expensive. It’s a special item, and what better place to stock it than at led4power.com

Hi Neven,

I have tried one of my 4-6 Amp LD-A4 drivers with a single SST-20 set at 4A high mode. I measured the tail current at only 3.73A, and voltage over the LED at 3.436V (which is spot on for 4A for this LED). This was on a fully charged NCR18650GA. I did not measure the current from the driver to the LED. Is the measured 3.73A tail current close to what the LED is getting? Something doesn’t make sense to me.

Neven, still waiting for your LH351Ds 4000K 90 CRI. What’s the forecast? Is there a point in waiting longer or I should look for something diffrent?

Your clamp ammeter is probably off by a little bit (somewhere in BLF I reported that UNI-T clamp meters can be off quite a bit, but I don’t remember which thread it was), when I’m testing drivers (with 0.1% accurate Rigol DP811) currents are usually accurate within 1% in 99% of cases.

 

I’m using a Fluke 319 that can zero before DC measurement. When this driver was used with the Luxeon V it was set at 5A and I measured 4.946A. It’s strange, because the Fluke 319 is supposed to have a 1.6% tolerance on the 40A setting. I’ll do a further investigation….
