Rapid Start lamps are used in combination with a rapid start ballast and are lit without the use of a starter. They offer the ability to illuminate a large number of lamps. They have a bipin base and can be used for dimming and flashing applications.

The colour of light radiated from a fluorescent lamp is determined by the chemical composition of the phosphor coating on the inside wall of the lamp. Black Light Blue (BLB) lamps produce energy in the near UV or UVA range (peaking at 370 nanometers). BL lamps must be used with external glass filters that transmits near ultra violet but absorbs the visible light produced. Electrical and physical characteristics are identical to regular fluorescent lamps.

Fluorescent lamps provide the following advantages:
Low operating costs
Long life
Excellent light quality
Superior CRI
Increased lumen maintenance
