When it comes to a light bulb to be replaced by an LED "bulb" which do not differ in size and shape, then the goal is reached with the LT-30. I unscrewed my 20 Watt Glübirnen and the new eingestetzt. None of my guests did it Friday night married one of the screws out bulbs with bare hands after burning all night. Nobody has bemekt that there were LEDs. In direct comparison, the LT-30 are significantly brighter than the 20-watt light bulbs. My 5-arm Leucher I run but now available with 15 watts instead of 100 watts. For me now it is clear that I ausrüste all convertible lamps with LED.
