it is to despair with the LED lamps, to be the sham a lawless space, here everyone does what he wants the lights are very bright, seemed in comparison with other bright, so I measured two varieties and compared in brightness, the lamp here indicated with 5 watts actually 8 watts, so the key lights up even brighter than the comparison lamp with 6Watt was specified (and also measured 6W) so watch out, because you can quickly once the transformer is too small (I've already experienced, as I have 10 piece 5W LED connected to a 60W transformer, the abschaltete after a short time, measured it - and lo and behold - each lamp 6.5W) There are even 3 Watts above the nominal value, which does not go the usual way replaces a 5 Watt LED lamp maximum a 35W halogen lamp and so you buy a the lamps now I have to replace the bulbs 40-45 Watt halogen - so bright I did not want it the light distribution is mediocre
