So, let me get this straight:
You're refusing to provide some information, such as "brand" and "model", but you are willing to state they are a knock-off an an American DJ light.
Help us to help you.
Are you having voltage issues as well?
Let me give you a couple of words of friendly advise, and this isn't a pro-ADJ plug either:
Please, buy NAME BRAND whenever possible, especially if this is part of your business. I don't care what brand it is, ADJ, Chauvet, Elation, Shure(there were TWO massive Shure busts this year) and so on. Be POSITIVE that you are buying that name brand, and not a fake.
Going back to those Shure busts, some Chinese companies were making Shure-branded knock-offs. Quite well made fakes though, but didn't sound right.
Make sure you buy from authorized dealers. This helps guarantee that you're getting authentic product. Buying authentic product ensures you get support and warranty support. Major important.
Yes, you may pay a bit more. It's so worth it. I can refer you to a highly reputable dealer that I do a lot of my purchases through. Based on your location and his location, you're almost local. I push all my lighting purchases through him, and sometimes other gear as well. I bought over $2800 of wireless mics last month through local dealers because I had a need right then and there though. You can contact me off-line or visit my web site to find his site, it is not hidden.
Another word on fakes. I'm a Disney fan, no secret. Doing casual research, I'm finding out about HUGE counterfeiting operations of Disney pins by the SAME factories making the authorized pins. Disney says "make this many" and they(the Chinese folks) make way more than that. It's hard to find many of these fakes because they are using the exact dies, materials and everything, just are basically unauthorized overages. They then sell these on the black market as well as through Ebay and other internet avenues.
Likewise, the fake Shure microphones were being sold packaged IDENTICAL to the REAL Shure microphones(box and printing, pouch, clip, insert, bubble wrap, manual, sticker, cable tie), but the manufacturing varied a bit. Good fakes, but still fakes and not the same quality in build and sound. The sellers were "hailing" from stateside United States, but the shipping addresses always came from mainland China.
Keep support concerns in mind as you buy cheap knock-offs. What you end up saving up front, you lose when you have to replace it when it fails. Here's another way to look at it: A Punch Pro sells for $399.99(listed on ADJ's web site). SHOULD this item fail within the warranty period, worse I am out is $25 in shipping. With a 3-year warranty, that's pretty darn good.
There is some brand selling cheap LED Par64's through Guitar Center. They remind me of a cheap version of the 64 LED's, not the 64 LED Pros. I just can't justify the cost savings. Not only are they not capable of doing what I want done, but the price point tells me there has to be other things to warn me about.
In the meantime, you should check with the company that made the product and ask them why they don't support their products. It is ALSO entirely possible that they don't support a full complement of functions, and may not even work in a master/slave mode. Only way to know is to read your manual and/or contact the folks who made it.
