  • Good purple lights.. not for lighting up Uranium glass.
Size: 40Ft
They light up and give off purple light. They do not activate my Uranium glass, so I sent them back. These lights would be great for many other uses...

  • Lengthy Strip Lights
Size: 40Ft
The media could not be loaded. Finally to Review….I’ve had my lights for a while (over a month) it’s your ordinary black light - white clothing/items and neon clothing/posters/items do glow in dark when light is lit. Perfect adhesive which was very easy to apply but I don’t recommend removing after you have stuck them to the wall. The length provided gave great coverage but I do still need to buy one more pack. Lifts came as 2 different strips that had to be attached together to electric cord in order to use - I’d recommend doing this assembly with extreme care as the strip lights can be a little fragile. I do wish these lights could have been a little brighter but you can’t beat it for the price - I recommend ... show more
