I'm getting ready to get into some flat par lighting. I've been doing quite a bit of research. I've found a model at a price I like. But I keep going back and forth on which color array to acquire. My biggest question has to do with whether or not it is worth the additional cost to upgrade to a RGBAW fixture? Is there any advantage to having white over amber? I see the additional 10 bucks per fixture being worth it for the amber or white, but are both necessary? Has anyone compared the 4 options?
