These LED bulbs are really nice and bundled at a really good price: the color is close to the original Halogen's but as you can guess with much less energy consumption which translates to much less heat. Trust me, this is very welcome during summer time. As indicated, they are fully dimmable so are instantly on as soon as you flow some juice into them. I got a few sets of 35W where I did not require 50Ws, and a few sets of 50Ws where more light was needed. One important thing to note is that the bulb's length closely matches the Halogen version as well instead of being shorter, so this allows to use them in fixtures designed for the GU10 original bulb sizes.

Very warm light and bright.
