Great help for cleaning up after puppy.
This is so helpful. Have a puppy and can see where he peed. Makes it easier to use my rug cleaner in the right area.

Great for illuminating glow in the dark toys
I 3D print with glow in the dark PLA and this light works instantly to "charge up" the glowing material. It's perfect for glowing crafts and the battery seemed to last a couple of months with occasional use.

BEST BUY EVER!!
This this is AWESOME!! it's great value for the money!! The battery life is incredible! The heat level gets kinda warm but nothing that can't be sent with. It's was the perfect size for what I needed. My mom found a dead baby horseshoe crab on the beach & gave it to my son, so I put I resin but I had to do it slowly and one level at a time. I did it on a day that has NO sun so having this light was a HUGE save!! Then I was able to prop the light up to go over the top, THAT was how it got so warm. But it was still awesome. I highly recommend you buy this, especially if you do a lot with resin

Doesn't Turn On
Put batteries in it & it wouldn't come on. Bought more batteries & put batteries out of the box in it & it still wouldn't work.

Cat pee problem: solved
This flashlight does what it's supposed to do, for the intended purposes. My cat decided that he was mad at my child and peed all over my child's floor. However I wasn't able to see the spots in the corners. So I ordered this, and I was able to see the spots and then clean them up. Definitely worth the value. Performs just fine and it's still standing up with the quality. The light obviously is UV (blacklight). So everybody reading this just know this is not a regular flashlight.
