Engineered to operate strictly on 277-volt electrical systems, 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.
