Compact design, small dimensions, bright light

The lamps fit perfectly in my ceiling track lights with G9 socket (see photo). The light is slightly whiter than halogen 28 watt, perhaps slightly brighter but pleasant. The power consumption at five lights: 5 x 28 watts = 140 watts (previously), 5 x 4 = 20 Watt Watt (after). Savings: 85.7%

ps after 7 months broke a lamp, the LEDs now light up just so that you can see them. Given the high cost I expect even a much longer service life. The dealer has refunded me the purchase price, a new I ordered from another dealer because I need identical for my Deckenbleuchtung total 5. One star deducted, now makes 4 stars.
