An HMPV Ballast for 80 Watt Mercury Vapour Lamps that operates without the requirement of an additional ignitor. Extremely low power consumption has made this a reliable and practical low cost solution over many years. Thermal protection is not required for this gear which measures only 92mm x 65mm x 47mm.
Great service. Fast (next day) delivery. Great price. The lighting units are more compact than I imagined but are very bright. Adding 4 to a small workshop that had old fashioned tube lighting has turned it into daylight! Being pre-wired meant I installed them (on chains) in less than an hour. Highly recommended.
