GREENIC UV Led Black Light Bulb 2 Pack, 8W (60W Equivalent) A19 E26 Blacklight Bulb UVA Level 385-400nm, Glow in Dark for Body Paint Club Party Neon Posters

Great bulbs for glow in the dark and UV reactive items

I use it as a porch light. Installed last October and haven't changed it out yet. Not real bright but gives out enough light. These were pretty pricey but they are worth it. Screws in just like a regular light bulb. Most times I forget to turn the light out in the morning but it's still going. Been almost a year. It's a soft purple glow.

Steady light emission, but not terribly strong output. Adequate for what I purchased them for, which was to emit light from the UV band that aids hydrogen peroxide in whitening yellowed plastic. That said, I did need to use both lights and point them more directionally than I had anticipated. Price was great, heat level was very low - which was good for me. If you’re using them to illuminate a room that you’re trying to accentuate color in, best get an extra set for anything larger than around 10x10.

work great

GOT FAST

we used this in a haunted house, room with black light reactive paints.... this did not get hot like old black light bulbs do, so its very safe. it made the paint glow just like the old school lights that heat up and cost so much. white really glows and glow in the dark paint also reacted well to this. we bought more right away! love these. safe alternative to the kind that heat up! i do recommend. see my photo of fish wall of reactive paints.

Worked amazing for glow day in my classroom!

The black lights arrived safely and in a timely fashion, however they were not strong enough for our use so they did not provide sufficient light to make uranium glassware really glow under their light.
