What a great wall lamp! Installation is easy and can even be modified as needed by drilling elsewhere (my electrical supply is not centered). Once the diffuser installed, the lights applies very well without being overbearing, and helping LED, consumes almost nothing (7.5W). The ignition is not quite instantaneous (1/4 second) because I think the small transformer inside of delivering 16V of LEDs but this is quite acceptable and has all the same nothing to do compared to CFLs. I had already purchased two Philips sconces that gave me satisfaction, it fully continues.
