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.

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.

I am impressed by the output of the bulb. I would strongly recommend using a metal flood reflector to concentrate the light. This would hide the bulb from view but increase the power by focusing 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!!

Takes a minute for this CFL bulb to fully warm up, but it throws a lot of UV blacklight around the room once it does. Can't beat that for only 20 watts of power usage. Looking directly at this bulb isn't recommended for any length of time. +1 year of infrequent on/off usage and the bulb is functioning just fine. BOTTOM LINE: Solid option for a bright CFL UV bulb.

I bought this for my kids but am very disappointed. It makes some white objects look a little bluish but not even close to what I was expecting. Just take a normal light bulb paint it with a blue sharpie and you will get about the same effect.
