Those curly lights are called "compact flourescent bulbs"----much cooler, use less energy, but some do give off a bluish light.
Halogen bulbs are VERY bright but hotter than blazes and the new LED lights (remember the new tiny Christmas light bulbs?)..are much whiter...no heat and VERY EXPENSIVE NOW...but the cost will be coming down in the next few years..
Perhaps you could replace a few of the bulbs with CFL (compact flourescents) for now so it would be cooler---just remember to look at colors in the sunlight...maybe one LED--it will last forever...
