Frequently Asked Questions (FAQs)

1. Is a regular light bulb UV?

Incandescent light bulbs, the most commonly used light bulbs in homes, give off small amounts of UV light. The UV light emitted by these bulbs is so small that it's impossible for human health to be affected in any noticeable way.

2. What bulbs produce UV light?

Incandescent bulbs emit low-dose ultraviolet radiation. Fluorescent bulbs emit varying levels of ultraviolet radiation, and patients should strive to use bulbs with the lowest irradiance. Chronic, low-dose UV exposure can cause cumulative skin damage.

3. Can I put a UVB bulb in a regular lamp?

New Member. I know many people who use normal desk lamps for heat bulbs and compact uv bulbs. As long as you do not use a ceramic as mentioned above and do not go over the wattage it says for that fixture it will be fine.

4. Is a black light the same as a UV light?

A blacklight, also referred to as a UV-A light, Wood's lamp, or ultraviolet light, is a lamp that emits long-wave (UV-A) ultraviolet light and very little visible light.
