Thanks… Soon I’ll try Luxeon V2’s and I hope they perform well under the Carclo 10507.

Neven, do you know if there’s a substantial difference between the Vf of your first batch of Luxeon V’s compared to the ones you sell currently?

If you plan to mix old and new LED, then it's important not to mix different voltage bins. Old ones were G bin, new ones are F.

No I won’t mix the different voltage bins. I was curious because I have one of the first samples in my Convoy S3 and the Vf was quite high compared to the SST-40 VH voltage bin. I’ll just move mine to my dad’s light and get the F bin for myself.

By the way, what are the voltage bins of all the different colour temp Luxeon V2’s that you currently stock?

I didn't buy full reels of those,so I don't have that info, but I measured ~2.82V@700mA with temperature correction, so it seems like they are X voltage bin.

Thank you

20mm LD-A4 and LD-B4 PCBs:

Hmmmm… So when will these be available?

LD-A4-20 in 2-3 days, LD-B4-20 a little bit later.

:+1: :beer:

Same firmware and features?

Yes, this is still LD-x4 generation, just 20mm diameter (with some pcb modifications for easier use, such as bigger wire holes and soldering pads).

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

I will see, it seems demand for optics is quite low, so I'm currently investing more in custom stuff not available elsewhere like MCPCBs.

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

You mean like this

That looks like it, indeed.

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

LD-A4-20

New mosX (called aluramic now) for Osram and Luxeon IR LEDs, 20mm and finally in 16mm size:

ALURAMIC 3030 20mm

ALURAMIC 3030 16mm

I will add linsings for Osram 4715AS-EA and Luxeon IR on these boards too.
