This lamp illuminates at least as a 40 W halogen (550 Lumens are earned), with a very open angle (120 °) which is very suitable when you want to light up a room like the kitchen or bathroom, thank you to the 16 "big "LED 5630 (5.6x3.0 mm). The fins are very convenient because they allow you to set the bulb in its housing GU10 very easily, which is less the case with smooth edges. But attention to the length of the bulb than a conventional halogen (the diameter is the same thankfully), and the color temperature of 3500 K is not really "Warm White" 3000 K which is rather less, but intermediate between warm and cold white (4000 K - cool white) that are not really suitable for rooms other than the kitchen or bathroom, although everything is a matter of personal taste ... Still unknown: the life. In summary, bulbs (re) order without problem, but do not hurry, the boat takes 3 weeks to come to Hong Kong.
News: these bulbs operate daily without any problems for over 1 year.
