First Light Technologies, Inc. offers High Output (HO) in all lamp configurations; these lamps will deliver up to two thirds more UV output than standard lamps. First Light’s HO lamps are offered with the standard HO filament or can be equipped with our long life electrode. First Light’s long life filament is a single piece construction, High Output filament. This filament provides added benefits over conventional filament types. This filament can be operated from 600 to 1200mA. Single piece construction offers greater durability and helps reduce the occurrence of premature burnout. The use of this filament offers greater UV output than those using conventional filaments.
