These 78mm Linear Energy Saving Halogen Lamps from Zexum are ideal for use in commercial display applications or for use with floodlights as they offer excellent lumen output, instant illumination and high colour rendition. The lamps in this range are 2800K Warm White Bulbs in a clear finish with a 1400-8550 initial lumen output, and are equivalant to a 100W-500W output of a traditional incandescent bulb, saving energy and performing to a high standard. Note: The switch-on surge of a mains voltage halogen lamp is higher than that of an incandescent lamp and hence it may be necessary to reduce the total wattage per circuit to avoid nuisance tripping of associated breakers. The use of dimmers will increase this problem and, in extreme circumstances, it may be necessary to reduce the installed wattage by 50% of the breaker’s rate capacity. If unsure, contact a qualified electrician. Main Features: Energy Efficient Linear Halogen Bulb 78mm Length R7s Cap Clear Finish Dimm
