Have the dimmable halogen energy-saving lamps bought to finally be able to use my uplight again. I have therefore replaced the original 300 watt halogen lamp, which really spent too much energy and was also disturbing noises. The heat development was on top of that scary. Despite my initial skepticism, I am pleasantly surprised by the halogen energy-saving lamp. The brightness is of course not as at 300 watts. But it is supposed to illuminate not work, but the living area to be wrapped in a pleasant light. And it's something they fully met. The warm light like and the brightness is also quite adequate. The lamp is well dimmable and without noises, with considerably less heat. Even with the fit I am very satisfied. For durability, however, I can give no estimation. But with the good price I would buy the product definitely be back when the stock is depleted. From me there is a definite buy recommendation, so long as there is no real and affordable alternative for a conversion to LED. Appropriate packaging and fast shipping have pleased me well.
