depending on the location, you can replace the 3 Watt LED lamp, bulbs from 25-40 watts. In particular, the rotating light is very pleasant. Especially in the passage area, hallway, staircase, is very pleasant, at once bright light, and not as energy-saving lamps, the effect that one 2-5 sec. Have to wait until the full light is available. I can only advise to connect 16 pieces have been used, not one was broken.
