Nite Ize Radiant MicroLight, Black Body/White LED

The Inova UV microlight isn't meant to be a CSI tool, but to cause certain materials and objects to fluoresce in darkness or impart a quick charge to Glow-In-the-Dark materials. This little microlight does that quite well.Some may want to use this to look for bio-spills and stains, but the brightness and power of this microlight requires those tasks be done in a totally darkened room at at close range. This is not for tracking blood trails in the night (CSI types often use a spray material that causes blood to fluoresce under UV; hunters find Coleman gas-lanterns or high brightness incandescent lights best.The UV microlight will reveal markers in newer currency in a normally lit room. From dusk to dawn it will cause fluorescing fishing line to visibly glow out to 15' and other materials to brightly glow at even further distances depending on exposed area. Two seconds exposure of a fluorescent marked watch face will cause it to glow for several minutes. Fifteen seconds exposure of glow-in-the-dark duct tape (Duck brand) will cause a glow lasting a very long while. (Exposing this tape to sunlight for a half hour will cause it to glow all night long.)So the Inova UV LED microlight does a good job illuminating or charging fluorescent or glow 'markers' on objects for those needing to find things in the night while not disturbing others or compromising night adapted vision. Inova's Blue LED microlight comes in second at these tasks, but is better at lighting a path in the dark, which is why I have a UV microlight in my tackle box and another in my tool chest, but a Blue microlight on my key-ring.

I was issued a few of these in Afghanistan. Rubbed the buttons off of them. Always wanted to get more, but the old company went away or something. Exact same thing from Nite Ize though. Flashlight bright from a keychain clipped to my zipper. Extremely useful. Had white, red, and green lights on my kit. Probably skip green unless you're wanting to signal with it. White and Red are perfect for EDC. Got a UV one a while back that was kinda neat.

I'm almost embarrassed to admit that it took me FOREVER to figure out how to change the batteries in this light!!! And I even went to the Inova site, which had approximately the same info as Amazon - "easy battery change, no screws, etc." Finally it occurred to me to take off the clip, force the two halves of the light apart with the tip of a thin nail file - and voila! - the two button batteries were plainly displayed! I have had the light for about 11 months and only use it for short periods a few times a week, so the original batteries still work. But I do need a night-vision-preserving SMALL flashlight, and this is definitely the best (and smallest) that I've used, or seen. The batteries are not cheap, but not all that expensive either - Amazon sells 4 Panasonic Cr2016 3v Lithium batteries for $5.79 (Prime eligible). I have saved the packaging, warranty info, and operating instructions from all sorts of gadgets, but apparently tossed everything that came with this flashlight into the recycling pile... Now that I have the clip off, I think I will leave it off, and use a lanyard instead.

Six months on and it's still going strong. This tiny light has undergone heaps of abuse - from banging around with the rest of my keychain tools and falling down a flight of stairs and yet it still works as well as the day I got it. I also prefer its sleek, compact form factor and thoughtfully designed stainless steel clip - I have absolutely no problem clipping it to any of my everyday carry carabiners. In fact, I'm at present looking for another micro flashlight and had put another brand in my shopping cart for a while but today, I looked at it and went, "Naah, why mess with the tried and true?" and put this into my cart again.I have used this in situations where I needed to check into ducts and ceiling spaces. A regular cylindrical flashlight would be just too unwieldy, as would a mini light that turns on by twisting its cap. I found that the best light for such use cases is this one, which I could just hold between my fingers and only needed to press on its wide body to turn on. I shouldn't even bother looking for an alternative.

The Microlight (red led) has found a permanent home on my key ring. It doesn't reduce your night vision and is great for reading charts in the dark. I removed the metal clip, which was awkward, and put my key ring directly through the same hole. It now fits flush with my other keys and is hardly noticeable. The red light is enough to see close up details like reading charts/maps, finding your keys after you drop them on the side of your car in the dark, but is not a flashlight. It has a maximum effective range of about 30" before it becomes too dim to be usable. This was a great purchase and has withstood several months of abuse banging around in my pocket. I would enthusiastically recommend this to a friend once the metal clip is removed.

I plan on putting this on the zipper pull on my uniform. Then I always have a light easily accessible.

Light weight and reliable. Just enough red light to preserve night vision.

Nifty and cheap little light I keep clipped to my ID badge for when I perform quick fluorescein eye exams. I have actually purchased 2 of these so I can have another attached to my keychain. It is a very intense light so I use the less bright option and hold it to the side rather than in central vision. Great and easy alternative to a wood's lamp or blue LED penlight. It's secondary use is helping me light my path when it's dark outside. Cool third use I have never tried is the strobe light function for a party... or to induce seizure....Note in instructions booklet that I found useful: if you hold the button down until the light goes off, you can change the operation so that one push is on, the second push is a less intense light, third push is a strobe light, and pushing it after a few seconds turns it off.
