Question: For a small shed, what would be more effective, this bulb or a blaclight tube and fixture? thanks!
Document: This light is as advertised. It fits in a small fixture. It is not as much a &#34;black light&#34; though as it is a purple light. It is also fairly dim. So, in my small front entryway, it cast a nice purple light that did make white objects glow just a bit. In a bigger space, I suspect it would not be even noticeable.
I bought two of these for my niece and I would say that two of them work just as well if not a little better than one two-foot tube light. She has them in a wall fixture, but I am willing to bet that putting them in a desk lamp that could be aimed would work very well. I recommend them for a little fun.
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.
)PRO: Fast and safe shipping, still shows UV on white objects, also only working on a desired small spot is exactly what i needed it for so this is also a pro since i only wanted it in one spot.Overall its pretty good, best you can get if you dont want Tubes with cords running up the wall and a clean nice effect. I would recommend this for it being a bulb.
The product came intact all thanks to the packaging.Powerful light, just what i was looking for.Very handy as well unlike the tube.
Package came in today. Unwrapped and placed in the fixture. Guess what happened? Absolutely nothing! I even tried it on 3 other fixtures and went to a dormmates room to try it. Didn't work. Thanks a lot. I usually try not to shop online simply because I can't see the product in person and this purchase just solidified my reasons.
We had another bulb similar to this one that was doing an adequate job until it was accidentally broken prompting me to find a new one. None of the local department stores had one though so I looked online at Amazon and found this one. Well it is very much more powerful than the previous one, maybe twice as much. In fact, I would say this bulb? puts out the equivalent of an 18&#34; florescent tube.
Will not buy again. (Original Review)This is not just another "purple" bulb, but actually puts out fantastic UV light. It is very comparable to my 24" and 48" tube style blacklights. It will light up items in a dark room that are over 20ft away. For a general use blacklight I would buy it again any day. However be aware that this bulb takes about 30 seconds to fully heat up and produce 100% of it's light. Packaged well and shipped extremely fast.
This Sunlight bulb is a significant improvement over my previous incandescent blacklight bulb choices. I would recommend this product!I have an estimated 45 sq ft covered porch I decorate for Halloween. Along with setting up an 18" blacklight 15-watt 120v black light tube (type T8) attached to the ceiling, the porch has two recessed can lights that I would put blacklight 75 watt 120v Incandescent bulbs into. For years I was unhappy with the three blacklights I was using.
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.
Answer: yes
