FAQs
UV LEDs usually have an operating temperature of around 122°F to 140°F (50°C to 60°C), and that’s based on the surface temperature of the lighting unit. This is fairly low compared to the surface temperature of some of the other main lighting methods,
UV LED lights are generally energy-efficient, particularly compared to older UV lighting technologies. However, electricity consumption depends on the wattage of the light and how long it’s used.
For example, a 20W UV LED light running for five hours consumes just 0.1kWh of electricity. At an electricity rate of 25p per kWh, this costs approximately 2.5p.
Smaller USB-powered blacklights typically consume very little electricity, while larger UV floodlights use more power to illuminate bigger areas.
UV-A and UV-C lights produce different wavelengths of ultraviolet radiation and are designed for different purposes.
UV-A blacklights are commonly used for fluorescent effects, decorations, artwork and detecting UV-reactive materials. These are the types of lights featured in this guide.
UV-C lights use shorter wavelengths and are typically found in specialised disinfection equipment. They can cause serious eye and skin injuries, making them unsuitable for ordinary decorative lighting.
For home entertainment, fluorescent decorations and creative lighting, UV-A blacklights are the appropriate choice. However, you should still avoid looking directly into UV LEDs and follow the manufacturer’s safety instructions.
