Quartz Tungsten Halogen (QTH) lamps are proven visible and near infrared sources, thanks to their smooth spectral curve and stable output. They generate little ultraviolet radiation and do not exhibit ...

For white light pick a bulb that's 3000K or so. Keep in mind that halogens use about 25 to 30 percent less energy than standard incandescents, while CFLs and LEDs use 75 to 85 percent less.
