I have this lamp coupled with an RGB WiFi controller and a 24 Volt 1 Amp power supply unit. So that I can adjust the light of the lamp in a rainbow of colors on a smartphone app. Besides the fact that you can not produce a correct white light, the lamp will be very useful and beautifully produced broad, bright light with vivid colors, no pastel colors like Philips. The installation depth is extremely low and the lamp is barely warm. Thumbs up!
