The light is a little brighter than the 20W halogen bulbs used previously. The color temperature is warm white, similar to the light bulbs with 3000 Kelvin. I have installed these lamps in 3 different lights. In any case, the installation was very tight, but possible. Since the largest part is not sitting in the back in the middle, they stuck something goes wrong, as amended. In one case, I had to leave out the glass cover. I think that's not so bad, it still looks neat. In 2 cases, the plug was too long and could not be plugged completely. I simply shortened to 3 mm with a wire cutter. Then it fit. In any case, I had the old electronic transformer replaced by a suitable LED transformer, otherwise necessary for the transformer minimum current of 20W is not reached. I have used for a DC transformer. Alternatively, you can a light bulb in it and only replace the other. The description of the lamp is not really succeeded: it is not screwed, but plugged and each replaces a 20W incandescent bulb. Overall I would recommend the LED lamps but.
