I have a charity hall that has some old metal rgb par cans from years ago. They are starting to flicker and give out. I control them with an Obey4 chauvet dmx controller. Would any of you fine gents be able to tell me a cheap replacement can that could be used with that same dmx controller (guys at the charity would struggle with a real light board)? Lots of Chinese cans out there....so hard to sort through. I just wondered if anyone had some good luck with one of the brands. These would be mounted and used once weekly at most. Thanks for your consideration!!!!!
