Review: As of late-2020 this is the one. - Who is this for? If you're curious about fluorescence (minerals, body fluids, terrestrial arthropods etc.) then this is the best consumer-oriented UVA/B flashlight on the market. The only place to go from here is even more specialized equipment meant for labs, and this generally means separate power supplies for wattages greater than 20W and prices *starting* at ten times that of this flashlight. How does it look? Three UV LEDs are powered by a custom triple lithium polymer battery pack. Two of these custom battery packs are included, each at about half charge. Their capacity is enormous and even with line power expect several hours for a full recharge. The LED-containing head of the flashlight can be taken off entirely and replaced with the dummy endcap. Putting this dummy cap on the open end exposes the charging ports on the base of the flashlight body, with a USB-C port for charging the battery and a USB-A port for discharging it to power a phone, e.g. There are two buttons, one for power and the other for selecting intensity. The flashlight can be locked, and prevented from illuminating, by pressing both at once for a certain length of time. It feels as heavy as a small handgun or large cordless drill and even though it has a lanyard I would not expect the nylon of this to hold up to a lot of swinging from the wrist. It's that heavy. What does it do? There are three intensity settings. In an interior space lit with many lights during the day this flashlight will fluoresce things from across the room on any of its three settings. At night or in perfect darkness indoors the effect is startling. You will see fingerprints and handprints on painted walls, huge numbers of them near highly-trafficked areas. If your drinking water has any concentration of iron or iron salts every surface in bathrooms will glow from the deposited metals. You will see fluorescent lint in several colors on every fabric surface and most smooth ones. This lint has been coated in the fluorescent chemical that laundry detergent contains to make white clothes fluoresce subtly in sunlight, making them appear cleaner than new. In some ways surfaces that do not fluoresce at all are more interesting than those that do. Porcelain cups or china plates generally do not have fluorescent glazes and these, when the flashlight is put on them, have a very deep and monochromatic purple color. It's startling to see white china become as darkly purple as if you had coated them in machinist's layout fluid. This is the very deep purple color of the Wood's filter and represents the most extremely violet light produced by the LEDs. This light is so next-door to UV-A, which is invisible, that it has a not-quite-there quality and lends this ghostliness to things it shines on. Human skin, particularly one's own, is also startling. Firstly because the beam feels like direct sunlight even though the total amount of visible light is in the arena of 1 watt. Age spots are greatly enhanced and even freckles that disappear during the winter are revealed in greater-than-summer contrast. The different bacteria that live on skin are shown, with those in hair follicles being a very striking orange. The visible light from the flashlight is greatly attenuated by the Wood's glass filter. Without anything fluorescing significantly it seems to be perhaps a watt or two of visible light (much less light than a single christmas tree bulb.) But placed over something fluorescent, like a glass of tonic water, there is very suddenly about as much light as a 20 watt bulb. This effect is very striking because it appears to violate the brain's way of interpreting cause and effect. Despite the fact that 20 W of UV light is a lot for a handheld device, 20 W lightbulbs are not very bright. It is therefore easy to wish even this huge amount of UV light were greater because the only thing to compare it to is not other UV flashlights, but those built specifically for visible light. And these, especially anything in this pricepoint, are many times as powerful. ***Eye Protection*** The cornea of the eye readily absorbs all wavelengths of UV light. This is done to save the retina from damage and protect the ocular jelly from becoming cloudy. However the cornea is transparent and poorly supplied with nutrients and blood. This means that damage done tends to accumulate. This is what cataracts are, and why elderly people are most affected by them. At any setting this flashlight will absolutely produce cataracts in the long-term and something like snow blindness (corneal sunburn) in the near-term. Window glass/flint glass absorbs almost all hard UV (UV-C) and around 60% of the wavelengths that pass this flashlight's Wood's filter (UV-A and UV-B.) This means that eyeglasses with glass lenses are not enough protection. Polycarbonate is a much better absorber of UV light. However even eyeglasses with polycarbonate lenses are not enough protection, as your corneas are still exposed from the side. Polycarbonate safety glasses with wraparound, one-piece lenses are the best solution. Anything made of polycarbonate will filter nearly all the UV light produced by this flashlight, or for that matter the Sun. The bottom line is that anyone using this flashlight and anyone in the presence of its use needs full eye protection made from polycarbonate plastic. Is it well made? Yes. This is at least as well made as a rifle scope, high-end handtool or pro kitchen equipment. The threads are all greased with Vaseline and the rubber gaskets seal well in their glands. Wood's glass is loaded with metals and is therefore much more fragile than even untempered windowglass. Because of this the filter is very likely to break if the whole flashlight is dropped. That said, every other component appears to be robust enough for heavy use. This flashlight comes in a small and cheaply made hardcase with adequate, low-quality foam padding. The first time I bought this flashlight one of the diodes had a manufacturing error that made it illuminate only about a third of its area. The return was handled by desertcart and a replacement (a-ok) was sent as soon as the defective one was in the mail. The total turnaround from noticing the defect to holding the replacement flashlight was 4 days. If you're curious about this problem in your own flashlight you can hold it close to a flat surface and look at the shape of the three blobs of light cast there. Good diodes should cast roughly square blobs of light. Defective diodes will show patterns that differ from the other two. This is also visible by looking directly into the head with protective glasses on but it is no better at verifying a defect than the indirect method, and should be avoided as a matter of principle.
Review: A light that makes rocks glow! - This light works well and illuminates Florescent rocks quite well. Battery is a standard AA which can easily be changed out without charging.

## Questions & Answers

**Q: Read many reviews about this flashlight, it is awesome, who would like to tell me how the flashlight perform in pet urine stain detection?**
A: These filtered lights work reasonably well at finding MY cats urine stains, and they are certainly better than the really cheap unfiltered LED lights that require you to wear yellow or orange glasses to see the stains. Nevertheless, depending on what they are peeing on, it still might be hard to find the spots. Not that you asked, but they also allow you to see every single place they ever vomited...

**Q: Can you easily switch from UV mode to regular mode? Or do you have to remove the uv lens first?**
A: There is no Switching.... This is UV Only.  It has a UV LED along with a UV Pass filter to limit it's output in the visual range (the Frequency that LED's are labeled as are where their peak output is, with light output going a good ways to either side of the peak  which is why we can still see IR led's that are 850 or even 940nm), So this won't put out white light.  Also this light gets very warm during use because the filter is absorbing a good bit of the output from the LED.   That being said I really do like this Light and the extra filter makes a big difference in keeping it outside the human visual spectrum.

**Q: How well does it work when verifying gemstones?**
A: Have not used in that application however when  cleaning the inside of a scanning electron microscope and looking for contamination I am able to see dust and partials clearly as with a regular flash light I can’t see dust with any distinction.

**Q: Does anyone use this for uvivf photography of, say, flowers or plants? thank you.**
A: You could.  Some minerals will glow.
