My project was setting up an RBGW strip around a new ceiling ledge (10m) - and I wasn't at all sure about drivers, controllers, voltages or anything. I contacted three companies to ask for what I needed and InStyle - replied first - gave the best explanation - competitive price I ordered and then had more questions which they answered via email inside an hour or two. Basically it's all a lot easier than I thought - but it helps if you're working with a company that doesn't mind answering your stupid questions ;-) .. and if course it all looks fantastic. Wireless Colour Wheel controller on the wall, on/off switch for the less gizmo friendly people, bright or soft white light, garish green or any other colour you want. Can't stop showing it off!
