This simple and practical ultraviolet (UV) nightlight project will illuminate your home with a beautiful soft blue/green glow at night. It is also bright enough to use as a small message board during the day to remind you of those important appointments.



You can write or draw on it using a standard yellow highlighter which glows a green color. I bought a pack of various color highlighters only to find out that yellow was the only color that would glow under UV. You may want to try your luck and see if you can find any other markers that work. If you do, please post a comment and share it with the rest of us.

S A F E T Y . N O T E :



The term "Ultraviolet", is misleading when used to describe LEDs. UV LEDs actually emit "near ultraviolet" light (400nm). This narrow wavelength falls within the same, much broader, band as regular fluorescent black lights. This means that UV LEDs are completely safe and will NOT damage your eyes or give you skin cancer - no matter what you have heard or read elsewhere on the internet.
