Standard Output Germicidal Lamps
"Light best manufactures UV germicidal lamps with two types of high-quality fused quartz, including doped fused quartz type and clear fused quartz, which emit a different wavelength of UV energy.
Ozone-free (L) lamps, made with doped fused quartz which blocks the transmission of 185nm energy, emit approximately 95% of the ultraviolet energy at the mercury resonance wavelength of 253.7nm.
This wavelength is the region of maximum germicidal effectiveness and is highly lethal to viruses, bacteria, protozoa, and mold.
Very-High (VH) ozone generating lamps, made with natural clear fused quartz can transmit 185nm and 253.7nm UV energy.
185nm can not kill bacteria or viruses directly, however, it can produce abundant ozone (O3) from oxygen (O2) in the air.
Ozone can break cell walls of microbial so that immediately kill microorganism acting as strong oxidizers and deoxidizers."

Typical Germicidal Lamps' Configurations:

Preheat Start germicidal lamps are operated by a preheat start circuit that employs a relatively compact and economical ballast.
The preheat circuit requires four electrical connections per lamp and a slight to moderate delay is needed to start the lamp.
Some modern electronic ballasts are capable of instant starting a preheat lamp, or available by changing the circuit.
Instant Start germicidal lamps are instant starting and utilize a coil filament on each end which operates a hot cathode.
Lamp life is determined by the life of the electrodes and is affected by the frequency of starting.
These germicidal lamps are extensively applied in air purification and duct systems (such as HVAC).
