HPI-T 2000W/ 646 E40 220V PHILIPS

MASTER HPI/ HPI Plus lamps are single ended metal halide lamps consisting of a quartz discharge tube, containing high pressure mercury and a mixture of metal halides, which is housed in a hard glass outer envelope, fitted with a standard screw base.They are available in either ovoid coated or clear tubular versions. They offer a unique combination of a natural white colour appearance, and high luminous efficacy both initially and through their long lives, giving many years of reliable operation, and making them an ideal lamp choice for many applications. Their high luminous efficacy reduces the number of luminaires needed, minimising installation and energy costs, while the excellent lumen maintenance and lamp life ensures high maintained illuminance levels and minimal maintenance costs.The colour point is on the black body locus giving a natural white light colour appearance.This combined with good colour rendering makes it easy to distinguish colours and ensures a pleasant ambience and user comfort. The excellent colour stability through life ensures good colour uniformity over time even with spot replacements. All lamps require a suitable ballast and ignitor ( except- S types) , and must be housed in enclosed luminaires ( except -P types) . The MASTER HPI Plus lamps are designed to operate on both HPL and SON gear. MASTER HPI Plus on HPL gear When operated on HPL gear, the MASTER HPI Plus lamps are light technically and electrically retrofit with existing HPI lamps. MASTER HPI Plus on SON gear When operated on SON gear, the MASTER HPI Plus lamps run at a higher lamp power, increasing the luminous flux and the luminous efficacy, reducing investment and energy costs. The colour temperature reduces, which is more attractive for retail applications. SON gear compatibility allows the possibility to replace SON( Comfort) lamps, offering a low cost opportunity to upgrade from yellow to white light, and also allows the replacement of competitors metal halide lamps which are typically operated on SON gear. The MASTER HPI Plus 400 W BUS and MASTER HPI Plus 400 W BUS-P lamps are specially designed self ( S) starting lamps requiring no external ignitor, saving on costs.This makes them especially suitable for direct replacement of Mercury ( HPL) lamps.The MASTER HPI Plus 400 W BU-P and MASTER HPI Plus 400 W BUS-P lamps are specially designed protected ( P) versions, suitable for use in open luminaires, i.e. no expensive front glass is needed.The teflon coating ensures that in the rare event of the discharge tube shattering, the glass is contained within the teflon coating and can still be easily removed. The maximum permitted bulb temperature for the “ P” teflon coated types is 260° C, 90° C lower than the normal unprotected types, which have a maximum permitted bulb temperature of 350° C. Inherent to metal halide technology, some visible colour differences may exist between individual lamps.To minimise these differences the burning position of the lamps should be within + / - 5 degrees of the nominal specified. Applications MASTER HPI-T/ HPI-T Plus - sportslighting, floodlighting of buildings and monuments, arealighting e.g. harbour, building sites, canopy lighting e.g. petrol stations, and horticultural lighting. MASTER HPI Plus - indoor high bay lighting, e.g. industrial workshops, exhibition halls, hypermarkets, shopping malls, DIY stores, churches and also the entrances of airports and stations.
