A19 LED Black Light Bulbs,Dimmable 9W Equivalent 100W,4 Pack

These do exactly what they’re supposed to and are less expensive than other options that I looked at. They gave a great black light glow for my party and fit seamlessly into my lamps and chandelier as they are the standard household bulb size.

The kids absolutely love these purple lights. They put off what you would consider a black light. Very soft and easy to use as a night light.

Really great bulbs, works well as stated and has excellent blacklight effects on white or light materials. I noticed that if you have it on in a room during the day where outside light or other regular lights are on the blacklight effect is not as strong, best in a completely dark room with no other light source. Also the bulbs don't get very hot with which I was pleasantly surprised.

Overall these are good, with a couple points to note: The overall heat output is pretty low. I let one of these run all night in a small lamp, and the top of the bulb stays pretty cool but the base (the area from the black section to the bottom metal part) gets fairly warm to the touch, but not excessively so. These will make some neon items glow (depends on the color, and how close the bulb is to the items) if the bulb is pointing straight up in a typical lamp. Unless you are aiming the top of the bulb directly at the neon items, you won't see the full effect. If you are looking for a "true" UV Black Light that only lights the neon items and not the rest of the room, get something else. However, if you want a really bright BLUE ambient light, these are the definitely ones to get. One bulb can easily light up an averaged sized room fairly well, especially if placed in a room corner with bare walls. In these cases, you might want to put it in a lamp with a dark shade. If used outside, the effect might not be as dramatic, but I don't have the means to try it. Regardless, for my purposes I am using these indoors only and I've taken off one star because of the excessive brightness.

I like the performance they put off the glow was fantastic but they don't last very long for an LED I haven't had mine went over a year maybe and they're already going out I believe I'll try a different brand

They work just wish a little brighter but room looks awesome.

These were perfect for our Halloween party. Great light level great quality.

Extremely dull for black lights

It burned my favorite lampshade
