🔦 2W Sunlite A19 LED Blacklight Bulb Review

Best for viewing fluorescent materials up close. Because it emits UV at 365nm, it has a higher UV to visible light ratio than many other black light sources, greatly reducing magenta cast. Stones that look pink in the cheaper black light look orange in this light. There is also visible violet light. The only way to further improve the ratio of UV to visible light is to add a UV filter. However, this light is not the best to add such a filter. UV filters are expensive, so you need a light with a

I used this bulb in a desk lamp to write with ink (Blue Noodle Ghost) that is only visible under UV light to get a brighter and wider illumination of the lamp, than this is possible with UV - flashlight. My intention in purchasing the bulb was to free my left hand to staple the page, not hold the flashlight. The result: The beam of a UV flashlight is vastly superior to it in all respects - in terms of beam width and beam intensity. I added a star to his overall rating because he is one of the…

perfect for my porch UV display. For reference, I fence off my porch to keep it pitch black and specially treat props to make them glow in UV light. Contrary to popular misconception, not everything "white" has to glow - when raw white objects glow it means you actually have bad UV light that emits too much visible blue/violet light. With that lightbulb as a spotlight aimed at the props, the porch remained pitch black while the props "flashed" only about 8 feet away - I might actually cover the

I bought different types of lights to test for a Halloween party. I tried 24 fluorescent tubes, a 23w black compact fluorescent tube and two other similar LED tubes advertised as 365nm. As expected, the neon lights worked well over a limited distance. The compact fluorescent lamp was more powerful and had a slightly longer range. The other two LED bulbs we have are definitely not 365nm and have violet visible light. This lamp surprised me, it was a step ahead of CFLs with a brighter effect and…

I love this pear. It gives the same light or visual impact that has made black light so fun and interesting in my life. it doesn't actually emit any light. It only makes things that react to ultraviolet light glow, and everything white suddenly glows bright white, but not bright purple like most modern black lights do. I have some posters with black light and UV art that I want to highlight the way it should without having to light the room. These little lanterns do just that. While they're…

So, let's repeat it again: a black light bulb shouldn't brighten a room or provide ambient light. The light from a perfect black light would actually be invisible, emitting only ultraviolet frequencies that the human eye cannot see. However, some paints and materials fluoresce under ultraviolet light, making blacklights both useful and fun. I bought 3 bulbs for comparison: ItUP black light blue LED UV lamp Sunlite LED UV 2W A19 black light blue lamp with E26 medium base Sunlite 20 watts and…
