These bulbs are perhaps most famously used in bug lights, or bug zappers. The light from a black light is much brighter than that from a blacklight blue bulb, because it doesn't attempt to block all visible light from the bulb. (The blacklight blue bulb's light is more purple, or violet.)
Black lights, ironically, not only produce more visible light than blacklight blue bulbs, but the light from a black light is actually bluer. While we typically refer to blacklight blue bulbs as "black lights," now you know that's not the correct term, at least in the lighting industry. So occasional exposure to a blacklight blue bulb is not expected to cause any health problems. UVA, which is closest to the visible light spectrum, is the safest of the three, and this is primarily the type of UV light emitted by a black light.

Since ultraviolet or UV light is infamously associated with skin cancer and potentially other health problems, it's worth mentioning that there are three types of UV light: UVA, UVB, and UVC. And now you know that was really a blacklight blue light bulb. So if you remember seeing your shoe laces glowing from a black light, this is why. But they can cause items to fluoresce, or glow, and this is why we get a fluorescent effect from these bulbs, which are often used in night clubs or at parties especially during Halloween. The rest of what comes from the bulb is beyond violet, or what we call "ultraviolet" - wavelengths that are too short for us to see with our eyes. Let's explore those differences.Ī blacklight blue bulb is a light bulb that purposely blocks almost all visible light from leaving the bulb, so you're left with only a dim purple (or violet) glow coming from the bulb. There are differences between these and what the industry calls a true black light (BL).
This is because certain objects "fluoresce" under ultraviolet (UV) light, which is what a black light emits.īut when we talk about black lights, many of us are actually referring to what the lighting industry calls a "blacklight blue" bulb (BLB). Many of those types of images would be something that is in the neighborhood of the 25 or 40-watt range.Most of us are familiar with the special effect of what we commonly call black lights - when everything else is dark, a black light makes certain objects glow in the dark. If you’re unsure about what you have, you can always send us an email with product images, and that should tell the story. If you are using these for a bug zapper, we need to know what’s on the lamp itself, we can’t cross reference from different manufacturers of bug zappers, there’s too many on the market, and there were no industry standards for which the lamp would be used in which unit. These are entirely different and used for different types of lighting applications. This bulb is different than the other kind of black light which is a black light blue, and that’s the deep purple color. It gives you that purple glow when lighting it up. They all mean the same thing which is a lamp that peaks in the 350-nanometer range to the exclusion of nearly everything else.

Many different manufacturers have slightly different code numbers for these lamps, but typically you’ll see something like 350, 350BL or BL stamped on the side of the bulb.
