Blacklight blue UVA 395NM led light
These are the type of ‘glow-in-the-dark’ light bulbs that most would associate with ultraviolet light. The wavelengths that these UV lamps emit are between 370–400nm, right on the border of visible light. Typical uses include:
Anti-theft protection
Nightclub lighting
Detecting forged bank notes
Carpet cleaning (to detect stains)
UV nail lamps
Scorpion detection!
BLB light bulbs are covered by a very dark blue or purple filter, and give off a purplish glow. Fluorescent tubes – either straight or turned into more compact shapes, like the example pictured – are the most common type but there are other lamp varieties available.
When using BLB lamps with UV varnishes or paints, check the manufacturer’s guidelines on the correct lighting needed to activate their product.
While BLB light bulbs are not hazardous to your health in the same way that germicidal UVC light bulbs are, they should always be handled with care. Wear gloves when handling them to avoid contaminating the light bulb, and ensure they are disposed of safely. Avoid long exposure where possible.
