Any reason why you think it wouldn't? LED's are just another DMX type of fixture. As far I can see, any DMX controlled fixture will work with any DMX controller. Maybe Something I am not understanding in your question.

It WILL work. BUT why would you use a typically par can desk for LEDS? in my honest opinion you would be much better suited with a different DMX controller. Such as a DMX operator 192. What LEDs are you using?
P.s. Welcome to the forums.
Sincerely,

I have a couple older Elation products and would like to make these work with the Chauvet LEDrain 64. I found that I could not use the Elation DMX PROGRAMMER. I will try the Stage Desk-16. This is for our Church and funds are limited. I may have to get your sugestion and move to a newer product. Thanks I appreicate your quick reply

I found the answer to my problem. I got out another LEDrain 64, set it up on channel 1, just like the other and used the DMX PROGRAMMER on channel one and all is working fine.
I went back to the light I was having problems with and reset all dip switches again and now it works. Dip Switches can give a address that you don't want. I should have known this from my old computer days. After 5 hours working with it, both lights are working as needed. I did call tech support to conderm that a DMX PROGRAMMER would in fact work with intel. fixtures. I Hope this will help others. Sodbuster
