The last one looks promising, though if I remember correctly these may not have enough oats to power the red LED's from the Casio projectors? I'll have to go find that thread...

Great find.

I think if they were adjustable... they would sell like hot cakes...

The PhlatLight is optimal at ~8A, max of 13A, but these are indeed a nice find, +1.

[BShanahan14rulz]

thing about the phlatlight is that it is a single LED, so low Vf and high current needed. Many smaller (but high-power) LEDs in series would be better use of these drivers.

Still, nice to know that, along with recessed lighting retrofit kits, they sell drivers for the things too.

The output voltage seems a little high :undecided:

A resistor will solve that problem easily, won't it?

Then put more LEDs in series :wave:

 

[bobhaha]

Thanks +1

Wouldn't the diode/load draw its own voltage, assuming the current is constant?

 

[BShanahan14rulz]

I think for a few of those drivers, the lower range on the output voltage is still on the high side. Personally I've not used more than a boost converter for LED with AA or a ldo linear for LED with Li-Ion

Now selling drivers?

^ yes, but those are drivers made to go inside flashlights, the ones hallucynogenyc
linked can be run off the mains voltage, good for things like labby style lasers.

 

[vegasf6]

Those newest mains drivers are the highest wattage ones they have, but not the only ones. I have a 6 led kitchen light running for 8 months now from DX parts. They have quite a few others as well. Not that I don't appreciate them being pointed out, I just thought the thread title was a bit funny.

 

[Gryphon]

^ohhhh, my bad

Got mine today...

I started by testing the SKU 42745, the 900mA one. Unfortunately, something is going on, the laser flashes, about twice per second, it is not a continuous emission. The emission has an average of 89mW (using Kenom's meter :yh

I will check the actual voltage and current in a few minutes.

Any ideas what is going on? Any suggestions?

I double checked all the connections, everything looks a-OK.

Thanks!

P.S.
I placed the question in DX too.

You could put a few diodes in series and drop the voltage of the 10vdc output model. Great find!
