This one is a 48 inch length and has bipin ends that are the same as regular F32T8 lamps. When a light bulb is shatterproof that means that it has a special coating that keeps the glass inside of that coated envelope. It's electrically the same as than non-coated version so you don't need a special ballast or anything like that. You can use it in the same fixtures that you're using the standard F32T8 light bulb with no modification. Even though it has this type of shatter proof coating, it still has an effective black light blue appearance. It's going to work well with special colors that can only be seen under a black light. This is the version that operates on an electronic ballast, so it's different than the older styles T12 version. If you have any questions as to whether this will work in the light fixture, please give us a call and we can help you determine that.

General information.
At, we have a complete line of various types of black light, but this is the BLB or black light blue version. These are fluorescent bulbs that use a particular phosphor that emits the black light effect, or it’s an incandescent bulb that blocks most visible light with a filter creating what is probably a lesser effect. When it comes to the fluorescent tubes, many people will call this an ultraviolet light, and it’s most commonly associated as mentioned before with unique types of special pigments that glow-in-the-dark. For most people, these are used for special display lighting effects, such as a theater production where a dark sky or some background needs to be indicated. It’s also used over Halloween where many people have their homebrewed displays and utilize the paints that that glow when used in conjunction with a BLB bulb. It’s also used where certain types of markings need to be identified in an industrial situation or sometimes with the TSA. All of those commercial applications typically use something that would be a smaller bulb or a CFL.

The specifics, please.
There’s nothing electrically different between these and other types of fluorescent or incandescent bulbs, so you don’t have to make any adjustment with the existing light fixture. There’s no rewiring that’s required or anything like that. Just plug the new bulb in where the old one was, and you’re all set to go. If you need light fixtures that will utilize any of these types, we have many selections for that in different kinds of strip light fixtures, cabinet light fixtures or something that’s maybe more industrial. No matter which way you go with it, you can be assured that this is going to work in any light fixture that has the same code if it’s a fluorescent or incandescent bulb. There are two different versions of this type of bulb; one is a screw-in type which could be an incandescent or a compact fluorescent. The other type is a linear fluorescent which needs to operate on a ballast which is inside the light fixture. There are specific lengths which work for certain types of light fixtures; they’re not all interchangeable.

What's the best black light bulb to use?
People often ask what’s the best lighting effect that you can have using a black light bulb. Most of the time that would be a linear fluorescent. It gives off the most significant amount of the black lighting effect although if you have an extensive area, you’ll have to use several fixtures to get that effect everywhere. You can’t just put one tube somewhere in the room and expected to glow everything with that black lighting effect. If you’re unsure about how many that you may need, we can probably help you with that so that you have a successful display or party or whatever you might be doing with this bulb. Right behind the linear fluorescent version ineffectiveness would be the screw-in compact fluorescent flood lights which have the same kind of phosphor. It’s very effective, but it needs to be used in close range as the light output is not high. Probably the least effective is the incandescent version because it’s a filtered black light. It does work, and it is low-cost, and for a lot of types of displays, it’s about the color that it’s putting off which is a purple color. But if you want to get that pop of glow that you get with certain types of paints and things like that, this would not be the right one to use.
