    Anyone know where I could get some schematics for a DMX controlled LED Par Can Light?? Can't seem to find anything :/

    So it seems that a "par can light" is a light in a large metal can, used for stage lighting etc, with a parabolic reflector. (I guess an LED version wouldn't have a reflector, but would be in the same style.) And DMX is an RS-485-based serial protocol that's used to control stage lighting and similar performance-related equipment.

    DMX requires a "smart" device, i.e. a microcontroller. So any project for a DMX-capable unit will have to include source code and a programmable device. It's not as simple as getting "some schematics". If there are no DIY projects for DMX equipment, that would be one reason. Another reason is that DMX equipment is normally used in professional applications where there is more money and less spare time available, so it makes sense to buy prebuilt products.

    If you're familiar with DMX protocol and have experience programming microcontrollers, and you provide some specifications (starting with the details of the LEDs you want to use), we can help you with a design.

    I dee jayed for a while till I realized the rest of the town was too! anyway I made a lot of simple stuff like that. for a par can I gutted a hi hat (recessed can light housing) and mounted a 300 watt quartz inside, hooked it up to a delay on relay and used it as a power strobe! I couldn't use it because people prone to seizures, it would trigger them so I quit using it. but they do make what you want, try seagull lighting

    You can pick up parts really cheap on AliExpress if it's basic DJ lighting you're looking at. You can build a circuit board from scratch or you could go with one of these instead. You can get a driver board with display, a power supply and a diode plate and build your own. Old PAR can housings will work fine. That's what a lot of Chinese companies did with overstock when PAR cans started to be phased out. They simply retrofitted the PAR housings with a back plate with a display PCB, power and DMX inputs and slapped a power supply, mainboard and LED diode plate inside. Presto!! LED PAR can!
