Halogen Lamps: Still the Standard to Beat by Craig DiLouie

Although LED directional lamps are steadily improving, halogen reflector lamps remain most popular for directional lighting applications and the gold standard to beat in terms of overall performance. Available in a wide range of configurations, halogen offers a number of advantages. Besides a low initial cost, the lamp starts instantly, provides excellent beam control and is easily dimmable across the full range of output. However, halogen lamps are vulnerable to competition by upstart LED based on three relative disadvantages: (1) low efficacy, as halogen lamps operate at 18-24 lumens/W; (2) relatively short service life; (3) halogen lamps emit more heat into the environment. www.lightnowblog.com
