I wasn’t expecting this to actually be a proper 365nm blacklight device, so when I tested it, it was a very pleasant surprise. Definitely NOT the sort of thing you want to shine on hotel beds.

One of the biggest effects for me was seeing my hi-viz clothing glow brightly without the usual purple reflection from the reflective tape. It really makes the LED phosphors pop too.

The circuitry is a nice simple boost converter with current sensing.

Here’s a link to the AliX listing I bought the light from. They do two versions. The deep violet 395nm and the proper blacklight UVA 365nm.

As always, I recommend using PayPal as a security layer when buying from AliExpress to avoid handing over card details.

This also keeps the channel independent of YouTube’s algorithm quirks, allowing it to be a bit more dangerous and naughty.
