Review: Worked as Expected - I purchased this to use with a windshield repair kit, which required UV light to harden the repair material. The kit was able to make use of sunlight exposure as a UV source, but I wanted to work in a warm garage and not have to wait for a sunny day. The light worked very well for this purpose. I used my USB volt/ammeter to check the current draw and found 5V/1.5A on high power (7.5W) and 5V/0.5A on low power (2.5W), which is close to the stated specifications. It's also quite interesting and fun to plug this into a small battery pack and walk around looking at things around the house under the "black light." :-)
Review: good light. - nice u. light, runs off a phone port bank just fine. it has more of a spot that flood. so if needing a uv spot light, this might be just the ticket.

### ⭐⭐⭐⭐⭐ good light.

### ⭐⭐⭐⭐ Great for fly tying UV resin cure
*by S***W on August 29, 2025*

I got tired of replacing the battery in my UV loon light for curing UV resin. This is relatively bright and seems to cure the resins (Solarez) that I’m using quite well, and just as fast as my battery light when the battery is fresh. My only complaint is that the on-button is hard to push, and the light has a bright setting, a dim setting, and a blinking setting (what the?) Which means you have to push the difficult button four times every time you use it.
