I can only recommend this LED, I have three pieces used in my ceiling trim, previously equipped with 3x35 watt halogen spotlights. So instead of 105 Watts only 15 watts and the light is much brighter, and I also personally feel cold white pleasant than the warm white, which always occurs very yellowish me. A few weeks ago should be as a radiator here more than twice the cost (the hardware store around the corner does a comparable product 27,90) that was me too expensive, but now for 10, - the whole thing even expects. I buy certainly then some. Because I spend all day in my office where they are burned throughout the day light by poor location and small size of the window expected, the spotlights for me after about 6-7 months about 1500 hrs. Operation and since I have not yet the electricity price increase from January with the calculation. If these things keep still only half as long as promised would be the approximately 4 years, then it was a real bargain, I am now looking forward to the burn time.
