10W USB Led Black Light Bar 2 Pack

Works great! I use it for lighting up a collection of Vaseline glass. The uranium in the green glass reacts with the black light to produce the MOST amazing glow. I got the idea from a display at an antique store and have been looking ever since for a small black light. I hooked it up to a cheap power bank that I tucked out of sight in the cabinet that the glass is displayed in. It's quite the conversation piece. Would also be great for Halloween decoration.

The GREENIC USB Black Light Bar set is a game-changer for anyone looking to create a vibrant, glowing atmosphere. These compact 1-foot lights pack a punch with their 10W UV LEDs, making them ideal for events like glow parties, Halloween setups, or even illuminating posters and tapestries in your room. The USB power option is incredibly convenient, allowing you to plug them into a power bank or any USB port for easy portability.The lights are lightweight but durable, and their brightness is impressive for their size. They provide consistent coverage, making neon paints and reactive objects pop brilliantly. Whether you're decorating for a party, creating a cozy vibe in your bedroom, or working on art projects, these black lights offer exceptional performance. The 2-pack option gives added value, ensuring you have enough lighting for larger spaces or dual setups. Highly recommended for anyone looking to elevate their decor or create a unique aesthetic!

Light output seems on the low side, you will need to keep these close to the object to get a good result.The strip gets plenty warm, measured about 110 F after approximately an hour

I bought these for bleaching yellowed plastic soaking in peroxide to restore it. (UV light activates peroxide and bleach.) They work surprisingly well. I imagine they would also work just fine for UV resin. I didn't think LED lights would have enough energy but they sure do. I did experience the light shutting off problem people have talked about and I think if it's not related to the light it's the power adapter getting too hot that does it. It doesn't come with the power adapters so you have to use a standard phone charger USB power plug of which I have many. I used 5V 1A plugs hoping the amps were low enough but after like 90 minutes one of them would shut off. So I just turned them off for literally one minute and turned it back on and they were fine. They are lightweight, like that lightweight model plastic so they feel fragile and the only downside is they don't come with plugs for the wall, which is fine since I have many and they are literally available for a $1 at any drug store. They work great so far. The lights themselves you can feel heat coming from but not much, just your power adapter needs to be able to handle them.

as ordered

Doesn't work as well as one would expect if you're using it for gemstones UV fluorescent stones this is not a good buy but if you're using it for like black light posters or such then it's okay but if you're using it for like black light posters or such then it's okay

cable doesn't come with a block

The only thing that could be improved is the double sided mounting tape they come with. Bright and good quality for the price
