12W Black Light Bulbs 6 Pack A19 E26 LED Bulb UVA Level 385-400nm Blacklight Bulbs Suitable for Party Halloween Blacklight Party, Painting, Body Art, Club, Bar, Fluorescent Poster, Neon Glow

These bulbs are fine for the price, but I can't agree with other reviews that say they're super bright. I purchased 3 types of bulbs - these 12W LEDs, some 20W CFL bulbs, some 15W LED BR30s. Of the 3 types, the 15W BR30 from GREENIC were by far the brightest and had be best light color/quality. These 12W bulbs are quite a bit dimmer (more than one would expect from a 3W difference) and the light quality is not as good - although per-bulb they are 1/2 the price of the BR30s so I can't complain too much. One of these bulbs started strobing about 3 weeks after purchasing - but again, for the price 1 out of 5 bulbs failing is OK.I ended up returning the CFLs - they had good light color/quality, but were very dim compared to the LEDs.

I put black lights in my man cave to illuminate the darkness and give me ambient lighting and I have had black lights for a long time but these LED black lights are so much brighter that you cannot shine them directly on they need to be in a lamp facing upward otherwise it's too bright I had a 5 goose neck lamp with 5 of them in edit basically lit up the whole room like daylight in pitch black so just be very careful because these particular lights are exceedingly brighter than traditional black they work amazing but they are succeedinly bright

These things are slick! Wanted a little spooky flair in the foyer! Love it! The light will activate all things blacklight! Just went from the old fashioned blacklight bulbs to the led.. amazing!! Way less heat, better light, the packaging was questionable, but seems to have done the trick! Just installed them, so I have no idea how long they will last but they are legit so far. The are kind of big too.. normal size base but large bulb globe, should be used for an open type fixture.

Very bright . I was happy with the packaging and the durable material. Will buy again!!

They are a whole lot brighter than I expected, and the bulb is larger than a normal bulb, so they do not fit everywhere a normal bulb fits!

The LED bulbs work alot better than the incandescent bulbs with a better area coverage but they are larger than the standard bulbs so beware if you are putting these in an in wall ceiling can because of the diameter.

I had 6 lights total in one room, they went great with the neon colors but I wish they were a little brighter.

They’re ok. One of them started flashing after 30 minutes of use and they do hum pretty loud. The brightness is pretty good.
