Is a halogen lamp an energy efficient source?
A – Halogen lamps are a type of incandescent lamp. In general, halogen lighting systems are not as energy efficient as fluorescent or HID lighting systems. For instance, the 300-watt halogen lamp used in a typical torchier (floor lamp with uplight) produces about the same amount of light as two 32-watt fluorescent lamps. For this reason, halogen and other forms of incandescent lamps should be avoided for general lighting, especially in commercial and industrial buildings. However, halogen lamps are more energy efficient than incandescent lamps and are energy effective choices in many specific applications. For instance, in retail track lighting, replace conventional 120 watt R-40 and ER-40 reflector bulbs with 60-watt PAR-38 halogen infrared reflecting (IR) lamps, saving 60 watts in every socket and getting more light on the product. Also, use 60-watt halogen general lighting bulbs in chandeliers and sconces instead of 75 watt “A” lamps and save 15 watts for each lamp. Because there ar
