Need help from an LED Guru!

[tinwhisker]

I have a couple of identical 120w chinese lights. 2 dimmable channels, one white, one blue. One got wet and about 1/2 the leds went out...using parts from the good one, through process of elimination I determined which component was bad. Its easily replaceable, but I can't find one to buy! I've been all through ebay and LED suppliers and cant find it. I think its a driver or a power supply. It has a dimmer on it. Can anyone point me in the right direction for a compatible replacement?

Inventronics has one but it costs about the same as your fixture.

It will also last much longer as you normally pay for what you get.

Its also dimmable via 1-10VDC analog

I have a similar one on my sump light and like it. The only downside is its not Class II but either is your fixture.

Cheers

Forgive me if I'm reading his wrong, but it states its 90-120VDC output, not 1-10VDC like the one you linked. Or did I miss the boat on this one?

90-120v is the output of yours. The 1-10v refers to the voltage used to control the dimming. It's from a different source (your dimmer) and is fed into the ballast.

Also if you search the PDF the 700mA version is 68-137VDC (much better than the 90-120 of your original)

Divide this by the lowest VF and Highest VF of the LED and you have the LED number range

For most Cree X series LEDs and 3 watt Bridgelux Knockoffs you have a VF close to 2.5-3.5 depending heat and drive current.

68/2.5=27 137/3.5=39 so with Vf given its extreme range this driver can drive 27-39 LEDs well within its margin of error... some simply use 137/3.2=42 LEDs for a max...
