new 1000w reflector lamps made by eye lighting. They are mercury vapour and are hard glass for exterior light fittings. They are rated to 46000 lumens and are stated to have an average life of 16000 hours. They require a 1000w mercury ballast to run and they don't need an ignitor. I got them from a stores disposal sale. To buy new they are about $200. I have a total of 7 and also have another 3 which run on 400v control gear if interested ask a question. they have a ges lamp base
