I bought this light bulb from Spencers and it's pretty good. The sound reactive feature though really needs to be close to the speaker. If you can put it physically on top of a speaker it works pretty good and it is super cheap.

You can pair it with one of those clamp work lights and clip it directly to your gear, that's what I did: https://www.amazon.com/Simple-Deluxe-2-Pack-Clamp-Light/dp/B088WB5NWT/
For the price it works fantastic in a small space, you can't get much better for cheaper than that IMHO.
