I use these (in white only...) at home, as workshop lights, and 10w is very bright indeed. With the colour changing you'd lose a few lumens, but easily enough for a pub stage area, or back-lighting, as you suggest. True, they won't use your current fittings, but they can be stood on the floor as they are, or easily fixed to a stand of sorts, or clamped to PA stands for side flood. As a bonus, they're waterproof for light rain, at least, so could be risked outdoors. I'll be getting a set like this for our next gigs, if I get well enough to gig again. Certainly not 'pro' quality, but those that I have are well made and reliable. Being LED, they are pretty well shock-proof, don't heat up much at all and last a very long time.
Just my tuppence-worth; hope this helps.
