Richmond Graphics Equipment Solarbeam SBL exposure replacement lamps; available in both 7KW (SBL-2) and 10KW (SBL-4). High UV output combined with a wide spectral response which covers both diazo and photopolymer films and emulsions.
It is best to supply the exposure unit with 208 volt. This will greatly increase the life of the bulb. It will only slightly affect the exposure times. The “actual” operating energy wattage of the SBL-4 bulb is 2,ooo watts and idle at 400 watts. When running at the full 2,000 watt energy level, the equivalent “spectral” exposure wattage is 10,000. This is because of the special “tri-metal” perfect spectrum wavelength result and the focused lamp reflector.
