They use a simple process where an electric current passes through a gas to excite the mercury vapor.
The functionality of the fluorescent lighting system depends on the chemical reaction inside the casing. Fluorescent Blacklightįluorescent lamps are low-pressure mercury-vapor gas-discharge lighting appliances that produce visible light using fluorescence. Because of this, users who don’t know better don’t always feel satisfied with their output. LED backlights set at 365nm are 20% more efficient than those that are 405nm. The wavelength of LED blacklight is specific. What Wavelength is Ideal for LED Black Light? You have a choice to specify the wavelength of light you wish to emit when you buy an LED blacklight. Blacklight with wavelength peaking at around 365nm will cover the whole bulb spectrum. This wavelength is relevant and is the best spot when creating the optimal blacklight effect.
Individual LEDs of 365nm are relatively expensive. Most blacklight LEDs sources range on the wavelength of between 385 to 400nm. We hope this helps you to understand the difference between black lights and blacklight blue bulbs - a somewhat confusing topic until you've seen the facts! Of course if you need black lights or any kind of lighting at all, we're here to assist by answering your questions and helping to take your order.LED UV blacklights use Light Emitting Diodes to produce UV light that illuminates fluorescent colors and materials. So you can keep your bug zapper at one end of the yard while you and your friends sit closer to a yellow or "bug repellant" light. Of course if you're looking to avoid bugs, yellow lights work best. Insects can see the emitted UV light and are attracted to it. You may recall the bluish glow coming from these devices. 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.
#FLUORESCENT BLACK LIGHT BULBS SKIN#
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). 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.
