My first glance fell on this lamp on the LED circle in the middle. . But these LEDs are already very bright Who wants to save properly, the fetches then LED - bulbs. Thus I may come consumption to 20 watts and save plenty of power. The design of the lamp also liked very much. The problem with the cultivation, I did pretty well solved. I (magnetic) taken extended a bit holder. Thus, the lamp was completely attached in 30 minutes. A compliment to the manufacturer I want to give more, because the LED only tackle if you want it himself. It does not matter if you pull the switch, or use the standard light switch.
