What Wavelength is Ideal for Fluorescent Black Light? The average luminous efficacy of a fluorescent lighting system is between 50 to 100 lumens per watt. This UV light then illuminates the phosphor powder coating on the inside of the lamp/tube emitting white fluorescent light.Įvery fluorescent light tube or lamp has this phosphorus powder. The mercury inside fluorescent emits UV light (short, medium, and long). 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. LED UV blacklights use Light Emitting Diodes to produce UV light that illuminates fluorescent colors and materials.
