Philips Master MHN LA Double Ended Quartz Metal Halide Lamps for stadium and sports lighting are available in 1000 Watt and 2000 Watt clear. They offer excellent colour rendering CRI Ra and high lumen output. These require a UV absorbing and protective front glass plus correct thermal behaviour for optimal lamp performance. Many metal halide lamps are interchangeable but not all. If you are seeking a cheaper alternative to replace your existing lamp, please call us and we will be able to advise you on a compatible product.
