Cheap is such a relative term. If people want true incremental ramping on a smooth curve of 1% or less change between values, but enough power and spread to handle anything in the hobby, but also not require any diy, I personally wouldn’t consider just about any option on the market “cheap”. Based on my own budget anywayYou can easily achieve a ramp up and ramp down with cheaper lights and timers if need be instead of spending on expensive lights. But now these days the programmable lights are getting better quality and cheaper so why not?
