I'm looking to setup a performance rig for doing live streaming, and would like to setup some lights. I'll have backing tracks all setup, and would like to use midi (running from Reaper) to run the lights. So, I'm wondering:

1 - How can I control lights with midi. I understand how dmx and whatnot works in general, but have no idea what is available to make this work.

2 - Are there good choices for lights? I don't need a lot, I'll be lighting up myself in a small studio, not a stage, and won't need thousands of watts of lights. I have a number of lights for film work, but nothing that is low wattage that can be dimmed.

3 - Are there small lights that are already midi controlled? I'd like to permanently install these, and the smaller the better.

If I was looking for a large stage installation than I'd know where to look, but for something small to use in my studio, I have no idea where to start.

1st hit searching in Google :]

As for lights, think 1 warm white led with 4 leds on a pole / t-bar will be plenty

1. I'm controlling light desk through MSC(MIDI Show Control) protocol. Some small lighting desks accept MIDI control on submasters. So maybe a small (24 channel) desk (something like Jester 24 by Zero88) might do the job.
2. DMX controlled LED PARs with RGBAW+UV are a good choice nowadays. Something like these ADJ Mega HEX Par RGBAW UV – Thomann Bulgaria
3. Never heard of such beast.
