Dear reader, What is the 50-units price for your Black Light Mercury Lamps (220V version)? Can you send a data sheet containing information on: - spectral power distribution - total optical output power - power requirements If possible, I want to drive these lamps from a DC power source, or alternatively a high-frequent ballast. They will be used in a machine vision application, so 50Hz output fluctuation will disturb our measurements. Thanks in advance for your information. I want to receive: Product Spec . Price Payment . Delivery Info . Minimum Order .
