FAQs
The Barrina UV LED Black Light Bars are a great option if you want strong UV lighting in a compact setup. They come as a pair and are easy to install, making them suitable for both small rooms and larger layouts. The seamless linking system is the main advantage – you can connect multiple bars together cleanly, so they’re ideal if you want a setup you can expand later.
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,
The main factor that determines the electrical usage of a UV light is the wattage of the bulb. For example, a 100W UV bulb uses around 0.25kWh of electricity every 6 months. This isn’t low usage but it’s also not extremely high, so they can definitely still be a good investment in the right circumstance.
