just great! We have equipped the training room in our physiotherapy practice with IWY WLAN LED bulbs. Our sports teams are excited and my colleagues and I also. No more complaints about the dazzling neon lights but the right light for each exercise. In the relaxation exercise at the end of each practice round I can, for example, dim the lights and enchanted the room through the wildest colors. This is easy with the remote control or with my iPhone on the latest Apple IOS version. Even at full brightness, the light is pleasant and does not dazzle. Good for our electricity bill; the LED bulbs consume much less power than our old lamps.
