Review: A UV BLACKLIGHT FOR THE UG GLOW - I collect uranium glass and wanted to swap out the standard fluorescent bulb. This worked fantastically. It intensified the glow even through the frosted glass. Very easy to insert into the fixture. A little pricy but it was well worth it. It was packaged very well. I think they used 2 whole rolls of bubble wrap. This is a uv blacklight. The uv is what makes the glass glow.I totally recommend this item.

### ⭐ Zero Stars Sold a bunch of defective bulbs
*by R***N on April 24, 2020*

I would not buy these bulbs from this seller. We have a large corporation that requires these bulbs to run a Saw Mill Grade mark reader. I bought 48 of these bulbs and went to install them in a time of need and none of them will light up and are defective product.
