Light ItUP E26 Blacklight Blue LED UV Light Bulb

What is "blacklight blue", you ask? Well, it's not "blacklight" in the traditional sense that everyone associates with. In this case, it's actually more of a dim grey-green. And this particular bulb puts out barely any light, which I was pretty much expecting, but hoped it put out the traditional "blacklight" vibe... which, again, this doesn't. I can't think of any application, creative or otherwise, in which someone would want to achieve the bland effect this bulb produces. The only thing it's got going for it is that it's LED and doesn't cost a lot to power.

So let's review: a blacklight bulb isn't supposed to illuminate the room or provide ambient lighting. The light from an ideal blacklight would actually be invisible, putting out only ultraviolet frequencies the human eye can't see. Certain colors and materials fluoresce under UV light, though, making a blacklight both useful and fun.I bought this bulb by Light ItUP and two by Sunlite:  Sunlite A19/LED/2W/BLB LED UV 2W A19 Blacklight Blue Bulb with E26 Medium Base  and  Sunlite SL20/BLB 20 Watt Spiral Energy Saving CFL Light Bulb Medium Base Blacklight Blue  to compare. Both LED bulbs are the same size as the standard light bulb and only get a bit warm. The CFL bulb from Sunlite is larger than a standard bulb and gets hot to the touch, so it may not be appropriate for a tight fixture.The fluorescent response from each bulb was about the same. They were very different, however, in their amounts of visible light. Sunlite's LED offering was the cleanest, putting out just enough deep blue-ish ambiance to read by. (Reading by the light of a UV bulb is definitely not recommended!) Sunlite's CFL bulb also did well and was just slightly brighter. Light ItUp's bulb was poor in comparison, emitting a lot of light of a strange and unappealing light blue hue. A "blacklight blue" bulb is supposed to filter out the visible frequencies and shine just the UV and this bulb was dramatically worse for that.Overall, for a "party bulb" I'd recommend Sunlite's CFL version. For the purest UV response, go with Sunlite's LED bulb.

This is severely overpriced in my opinion. There are only two tiny LED's inside this light bulb. I'm not sure what the wavelength is but it doesn't seem to light up white objects as well as my handheld UV flashlight does. It just didn't seem to work for my application.

We needed the Black lights for a school project. The black lights in the store didn't illuminate the room like we were hoping. So, we tried these. They worked great! A little expensive, but worth the money for our project!

Cheaper bulb just as good if not better

Low quality, plastic lens popped off after 2 days

Good black light for our glow in the dark project. Exactly what we expected.

Light bulb is not like a black uv light. It does give a light purple color, not was I was wanting. Also when I received the product the plastic dome was not attached to the base of the bulb.
