So after reading the reviews I was skeptical about buying socket bulbs, but after buying two different types, this one is by far the best and even comparable to the other tube black lights I bought. My roommates and I throw black light parties, and these worked great for places like hallways and the bathroom to keep the mood going when not near the big tube ones. They make black light reflective things glow, as well as make the whites glow blue. It lit up my whole kitchen, and not with the annoying blue or purple light, but with true black light, to the extent that even clear plastic cups had a blue glow tinge. Not too bright, but they definitely work in the pinch areas. If you are thinking of using these for black light parties or to just light up your small to medium size room, these are almost as good as getting an 18" fluorescent tube light, and definitely the cheaper alternative.

I have no complaints about this product; it performs exactly as expected.

We intend to use it as part of our Halloween display. When I saw the word "blue" in the title description of this item, I was a little worried that it wasn't a true 'blacklight', but now that I have it in hand, I can confirm that it works great, and has produced excellent results with our flourescent paints. Now that I know the bulb meets our needs, I intend to purchase several more, to incorporate into our Halloween displays.

This light gives off a lot of visible purple light and not much ultraviolet. I doesn't make things glow well, and the visible light masks much of the glowing of objects. I'm comparing it side-by-side to a fluorescent tube backlight that I've had for many years.

I ordered two for my son's birthday party. I've been testing them out in different places in the house (bathroom, bedroom, walk-in closet) and they work great. Everything that can glow does- white, neon, words written with a highlighter. I even discovered items that I didn't realize would glow, like a bright orange laundry bag and a belt. Much better than the other blacklight lightbulbs we have. I'm ordering two more because our basement has four light sockets.

Update- June 19--Just had my son's party and the light was fantastic. Made everything neon or white stand out! The party got rave reviews from kids and parents thanks to the lights.

Yes I recommend this as a great black light bulb that works like it should and can screw into a light fixture which is great when you don't have room for the long tube systems that black lights are usually associated. I say this bulb works like it should and gives a wonderful black light effect that does not hurt the eyes, but is bright enough to do the job, you will not disappointed for use in black light parties or poster lighting. I have a black and white poster that looks great with this bulb. This is not the cheap ineffective standard black light that goes for light fixtures that just glow purple, this bulb glows like a black light should, your whites will stand out and anything that glows will look brilliant!

This is a reasonably priced solution if you need a black light. It fits into a standard lamp socket and provides a decent amount of true "black light;" enough to show off dayglo colors and make white clothes glow that beautiful, deep blue. This light works a whole lot better than other "spiral" type "black light" bulbs I've seen.

It's only 20 watt so don't expect the amount of light you'd get from a four foot tube but this is a whole lot easier to handle and to fit in a tight space. You should also plan to use it without any kind of lampshade. It's just not bright enough to penetrate. Use it in a clip on utility light with a reflector to focus the light and protect the bulb, or something similar.

Handle with care, of course.

I would give this light four and a half stars if I could and five it it was only a little brighter. Really, it's a good bulb.

My kids and I have been making all sorts of Halloween crafts that glow under black light, so we needed an affordable solution to make them glow in the window!

I easily installed this bulb in a standard light socket in a lamp we had (one with a moveable goose-neck to move around). I positioned the bulb about 24 inches above the objects. The bulb makes plenty of light to illuminate all our crafts in a large bay window. It doesn't light up the whole room, but definitely enough light for a window display. Plus, if you stand in front of our house on the sidewalk--the entire window area seems to be glowing purple! The kids think this is awesome!

I'm buying more for our driveway lights for trick or treat night!

I just uploaded photos to show how I'm using it!

I purchased this bulb about a week or so ago and at first.... I received the wrong one! Bummer :(

To my surprise, however, when I selected to return the item, I was sent (overnighted, in fact!) the correct bulb at no charge. Super stoked on that.

Now for the product itself. It is a great little light. One bulb can bring a good amount of UV to my 8'x18' room. Of course its not going to be a grand veil of blueish purple engulfing the room so dont expect that. The amount of UV produced gives a good glow out of just one bulb and enough to illuminate posters and paint. I am considering ordering another for more coverage but am very please with just the one so far!!
