Halogen & CFL Lamps

These lamps are mainly used to maintain existing installations where a direct replacement is required. Match the base type and wattage to the lamp being replaced, and check any special requirements of the fitting, such as a transformer for low-voltage halogen. Where a fitting allows it, switching to LED usually cuts energy use and maintenance considerably. LED equivalents are available for most common halogen and CFL lamps; compare by lumens to keep similar light levels. If an installation uses dimmers or transformers, check LED compatibility before switching.
