40W Black Lights for Glow Party, Blacklight Flood Light with Plug, IP66 Waterproof LED Black Light for Halloween, Blacklight Party (2 Pack)

I purchased the two lights which came quickly and glad they did. First one just stopped working on its own accord after 84 hours. Then the second had water under the glass and off course didn't work another 4 days after the first issue. All my other lights work fine in these weather conditions but these. Now I'm having a hard time returning them in the allotted time due to NYS covid hours.

Someone in the comments mention that UV light will help to spot smoke from a (glycerin-based) smoke generator (for automotive use).I will tell you right now: NO IT DOESN'T.In fact, this UV light makes it WORSE for spotting smoke in this case.Other than that, it works well for spotting UV dyes, no problem.Like others who have left (negative) comments, reliability is questionable.I was originally going to use it sparingly on automobiles, so I wasn't too concerned.Buying the 2 pack came in it's own packaging with a foam divider, so the units were pretty secure for shipping.

They functioned well, initially, but burned, fried some of the lighting lcd's from either getting too hot or too much voltage being sent to them.The cooling ability is not sufficient enough to keep it cool, maybe... It is a neat product, it is well insulated from water, but that means that it needs extra cooling. Both burned-out. Now, they don't work and there IS NO WAY to contact the manufacturer, to get a replacement, AS THEY ADVERTISE.

About 33 days or so they quit working Amazon replaced purchased another set same thing quit working Please note I am using these indoors in an arcade Room that I built these are not being used outside so in my opinion they are very defective

Don’t buy these. Mine was bought Sept 18 and already stopped working and I can’t find anywhere to use the supposed 18 month warranty. No results from search for greenlifeus nor Lysed. Out of return range for amazon warehouse returns. What a waste of money.

I bought these and then just plugged them in about two week ago. Out of four, three worked. Then after two weeks only two worked. Expensive for 50% of purchase to function as advertised.

Stopped working after about 3 months

I caught these on sale so bought the 2 pack. Works great for curing 3d printed resin models.
