ULTRAVIOLET BLACK LIGHT BULB 75 WATTS A19 LONG LIFE UV BLACKLIGHT BULB - Bulborama Industrial Grade 5,000 hour lamps are engineered to last up to 10 times longer than standard bulbs, therefore reducing operational and maintenance costs, and saving both time and money. Industrial Grade lamps are built with brass bases to prevent socket corrosion and multi-support filaments to resist shock and vibration in any burning position. THIS ITEM DOES NOT FULLY ILLUMINATE PAINT AND OTHER PARTICLES. ONLY "BLACK LIGHT BLUE" BULBS PROVIDE THIS EFFECT - PLEASE SEE BELOW: All Bulborama black light bulbs emit their light as UV. However, standard incandescent black lights such as this item contain UV that is the long-wave type commonly used as a party bulb or for pet applications. If you are trying to fully illuminate paint and other particles, what you are looking for is a "Black Light Blue" bulb, which is typically and most efficiently fluorescent. Fluorescent "black light blue" bulbs can use only one phosphor, and the glass envelope of the bulb is a deep-bluish-purple glass which emits only UV and no other visible light, allowing for the illumination of paint and other particles.
