Customer Reviews

Two broken bulbs, broken before shipped to me


Received 4 bulbs, and two of them were broken - in several places - before being put in the shipping box. The shipping box was in really good shape, but two of the bulbs were added broken. The other two are very dim. I am not happy with this purchase.




great service


Great company. I did not unpack my shipment until one week after delivery and found a damaged bulb. One email to the company and a new bulb was sent at no cost. Great service

Black lights worked like a champ for our Glow Party


Worked as advertised. Because of the large area we have we had to use 20 bulbs to get the full effect. We probably could have gotten away with 12 bulbs

I bought two of these to light a small stage - worked fine.




Excellent black light


Hight quality black light, made all reactive materials glow brightly without casting a visible light.

i am looking for the same type of black light bulbs they used in the seventies. is this the exact same bulb?


The black light blue bulbs can be used for special effects, glow in the dark and nightclub applications. This is similar to the types of bulbs that were used in the 1970's for those types of applications however; the diameter and wattage are most likely not the same. If there is a fixture currently in place, we suggest verifying the type of bulb is takes.

What is the best black light tube type to use to attract bugs at night? It seems there are many types of bulbs (tube, reflector, etc) and different fixtures as well. I've heard that a "white" black light is the best for attracting insects at night. Please advise, Thanks rh


This particular type of black light is not used for insect traps. We do offer a number of bulbs that are and you can find them by using the following link.
