He did us a great service on Christmas night 2013, placed on the top of the chest, more light from 7:15 p.m. until 3 am during the violence of the wind burst, the storm that ripped electrical son . It does not nearly all. We spent Christmas with this lamp, and luckily it was there. Busy the day before, I highly recommend it illuminates very well a room of about 25 to 30m2, carefree, I do not regret.
