Black light and black light blue fluorescent lamps use phosphor that emits mainly near ultraviolet (300 to 400 nm) light. This allows users to take advantage of the photochemical and fluorescent action unique to ultraviolet rays. The BL is also used in electrical insect control units to attract insects.

Designed to emit only near ultraviolet rays, black light blue fluorescent lamps are made of special glass tubes that do not allow visible light to pass through.

NEC sterilization lamps are made of special glass that allows ultraviolet rays to pass through, and are designed to emit large amounts of 253.7 nm ultraviolet rays that are close to the maximum effective sterilization point.

With high-color rendering fluorescent lamps, the emphasis is placed on color rendering rather than brightness. N-SDL lamps are rated at a color of temperature 5,000K and have an average color rendering index value (Ra) of 92. This makes them ideal for fresh food showcases.

Developed with the emphasis on color rendering rather than brightness, the CW-SDL lamp is rated at a color temperature of 4,200K and has an average color rendering index value (Ra) of 92.
This lamp is ideal in places where a fresh, natural look is required, and can also be used in hospital examination rooms.

These lamps enhance reds and are popularly used in butcher shops to make meat displays highly attractive.
