Engineered to operate strictly on 277-volt electrical systems, PAR38 and long-neck PAR30 lamps are an energy-efficient replacement for conventional halogen bulbs in retail, hospitality and architectural applications where converting voltage would be costly or labor intensive.Suitable for spot or general lighting, the lamps feature instant-on technology and deliver a high-quality light with excellent color rendering for applications such as shops, lobby and reception areas, corridors, stairways and washrooms.
