Verbatim says its PAR38 LED bulbs can reduce energy consumption by more than 70 percent when used to replace a halogen PAR lamp of comparable output. The five bulbs in the collection come in warm color temperatures of 2,700k, 3,000k, and 4,500k. All but one are fully dimmable. The maker claims a 40,000-hour lifetime for the bulbs, and backs it up with a five-year limited warranty. Prices range from $15 to $50.
