I have a set of track lights from Ikea that are over 15 years old. (Ikea model name was Magnesium.) They came with 20-watt halogen bulbs, so the set of 5 lights used 100-watts. These replacement lights have the same color temperature as the originals, they use a quarter of the electricity, and they run cooler. They are actually brighter than the originals - which can be both good and bad. I think I'll get used to the brighter lights and be glad I have them.
