No, all black lights are not the same, although they function in a similar way. There are primarily two types of black lights: incandescent and fluorescent (including LED).
Here's a breakdown:
-
Incandescent Black Lights: These are similar to regular light bulbs, but they have a special filter that blocks most of the visible light. They primarily emit UVA light.
-
Fluorescent Black Lights (including LED): These are more energy-efficient. They use a phosphor coating inside the tube that emits UVA light when energized. LED black lights function similarly, but use LEDs to generate the UVA light.
While both types emit UVA light and make fluorescent materials glow, there are differences in their construction, efficiency, and the specific spectrum of light they emit.
