The custom LED driver was wired to a string of 6 – 365 nm UV LEDs with a total of around 15 watts.
Here’s a video of the lamp being used. It’s not very bright because it emitted only a small amount of visible light.
Here are the pictures for the lamp construction. A fan wasn’t installed so the second switch wasn’t used.
This lamp was used to test for the UV protection of the goggles. If the highlighter ink doesn’t fluoresce, it means that UV is blocked. You can try sunscreens too.
When using a UV lamp, it’s important to wear UV protection goggles even though our eyes are insensitive to its wavelengths.
