Barrina Black Light Bar, 10W 1FT Magnetic LED Black Lights, for Glow Party, Fluorescent Poster Paint, Blacklight Halloween Decorations, Linkable UV Light, Plug with Built-in ON/Off Switch, 2 Packs

I purchased one 4-pack of the 2-ft bars, and I think they are working out well to supplement some Halloween decorations at the house. If you look at the pictures of Halloween decorations, you can see what I did. I placed 2 of the bars in the window sills to the left inside the house pointed up. With the white blinds, I think it looks kind of cool. I placed the 3rd under the porch to provide some backlight behind the ghouls. The other pic shows where I mounted that one. Not sure what I am going to do with the 4th one yet. The pictures really do not do the lights justice. Also used them for a fun photoshoot LOL Installation was very easy in part because these things are very light. I suggest figuring out where you want the bar(s), mount the brackets, then snap the bar into place. Before I used any of them, I tested the AC cables and the link cables and they all worked great. The kit also comes with little connectors that allow you to link the bars right next to each each if you want to create a more continuous light. Overall, I am very impressed with this 4-bar kit. As long as they last a reasonable amount of time, I will keep my review at 5 stars. If I experience any issues, I will adjust accordingly.

This is a great little UV black light! It’s bright and covers a good amount of area. It’s perfect for my shelf display. I bought this one because it can be plugged in to both a regular outlet or used with a USB. You can also plug the 2 light bars in together to cover even more area.

Works just like they should and they snap together so that's helpful! Sturdy and size was nice doesn't flicker and it's a warm ambient glow really like them might get a second pair but honestly could get away with just using the one I have it glows nicely and it's sturdiness so easy to assemble I just snapped together found metal on my ceiling and the magnet immediately popped went into place installed I'm impressed with product and myself I am not bob the builder

Rapid-fire Review: As a person who has owned several classic "tube" black lights, I can safely say this is the best product ever for UV enthusiasts. It's simple, easy to use, and affordable. Low cost, energy-saving, with very small detectable heat signature from the bar itself. I think it's quite safe, though I wouldn't recommend keeping UV lighting on 24/7, just as a precaution. It would be smart to mount these bars in a way that the beads are not in direct sight. It makes more sense to angle them toward the ground or the ceiling. Use furniture or other methods to block the direct rays hitting you in the sensitive eyeballs. The company included a set of plugs for each of the four LED bars I ordered, as well as connector rods that turn multiple bars into one long mega bar. That means I can light four different places around the home or chain them together and use a single plug to control all four bars. I like how versatile this kit is. If I ever plan to expand my UV into a bigger space, I will definitely search for this product again. The 3-prong connecting rod is NOT strong enough to keep the bar together. You'll need to use the metal brackets to keep the bars in place on the wall, if you choose to mount them. Otherwise, you could possibly use clear tape to keep the two bars from wobbling away and loosening the gap between them. I don't know for sure if tape is recommended, so don't even try it unless the manufacturer says it's safe. For me, I was able to keep the 3 of the bars chained together, vertically positioned in the corner of my room with a little finesse. I do not trust them to stay connected if they were to topple over. I think that bending the mega bar, once chained, may result in permanent damage to the lightweight aluminum housing. Don't be dumb and clumsy, make sure you have a plan to mount these guys before you connect them and ruin your investment.

The 48" version of these lights are actually only 46" long, which isn't a big deal if you just want to use them for fluorescence and other general purposes, but it's something to consider if you plan to use them for exposing alternative process prints (which is what I use them for), screen-printing plates, etc. Your final coverage area will be slightly smaller if you mount them length-wise in a UV exposure unit setup as I did. Beyond this one caveat, though, they're great lights at a fair price. They come with several connection/daisychain options, including connectors that let you butt the fixtures end-to-end up to 8 in a row from a single power input (you could probably do more, but that would pull quite a bit of power through all of the fixtures, which might cause premature failure, so I wouldn't risk it), 4-foot cable connectors, and even just individual power connectors with inline on/off switches. Some have knocked the metal clips that come with these, but I found them to be fine for mounting to flat plywood. I don't think I'd trust the screws in drywall or on ceilings, though, since they're really short. Get longer screws if you want to mount them to such material or surfaces. They put out a lot more visible light than fluorescent blacklights, but my goodness do they ever put out a lot of light overall, including UV light. Each bar uses 22 watts, and since LEDs have about a 6:1 ratio of light per watt compared to incandescent, this is roughly equivalent to the light output of 132 watts of incandescent light per bar. That's pretty great. And, since the UV light these things produce is in the 395-400nm range, they're less dangerous than fluorescent blacklights (the purple kind), which put out mostly 365nm UV, which can still cause freckling and even mild burns at close range when a lot of them are used, as I do with my alternative process photography. I've included photos of the exposure unit I built using 16 of these bars to give others who might want to use them for this purpose an idea of how they can be set up. It's pretty easy, and much less bulky/heavy than using fluorescent tubes while also being much less prone to breaking, since there's no glass, only metal housings with durable plastic lenses and end caps. Overall, I give these lights a 4-star rating, dinging them 1 star only for their being 2" shorter than the advertised 48" length. Also, they ship in their factory box without any additional protection, so they can be bent and otherwise damaged pretty easily in transit. One of the four sets I ordered came bent like this, so I had to exchange it for another, but Amazon makes that very easy. This lack of extra protection is a shipping issue, though, not a product issue, so I didn't ding them for that. I highly recommend these both for fun and for more critical uses. They're easy to install and use, and their installation options and versatility are far superior to fluorescent fixtures while also taking up less space and weighing less. I'm highly satisfied with these lights.

Muy buen producto. Fácil de armar y de usar. Lo ocupé para la decoración de Halloween/Día de los Muertos, y le dio un ambiente espectacular al área decorada. Tiene alcance para una habitación. Saludos.

Fonctionne très bien

I used these for a UV glow party in my basement! 4 lights were good and bright enough that no other lights were needed. They’re super light and had a pretty easy installation process. They lasted all night and did not get extremely hot. Only issue with them is the short cord - I was able to use 4 separate extension cords to solve this issue. Since they were all too far apart (5 ft apart) they were unable to share extension cords. Overall, very happy with the lights!

These worked super well, a great value for what you pay for them. I didn’t want to put holes in my wall so I was only able to keep them on my tv cabinet, but they still worked well from below.

Product was good not as bright as I thought it would was my only complaint about the product itself. The seller is incredible i had an issue and they were very quick to resolve it, i would definitely buy from them again
