YZYOELED Three Light Source Jade Identification Flashlight, 365nm Ultraviolet Detection Lamp, Jewelry, Gemstones, Antique Beeswax Banknotes Verification.

What's not to like its very well made. Works great!

I ordered this flashlight for antique hunting. It offers a white light, a 365nm U.V. light, and a yellow light. I don't understand what the yellow light is for or how it is used, but it is yellow.It comes in a cushioned case and has a very nice lanyard, a cone that narrows the light output, and a charger for the 3.7v 18650 battery. The charger has a USB cable that will fit most charging ports and power adapters.This light will be perfect for my needs...stalking uranium glass and other treasures, but the design of the three LED lights causes the beams to be off-center. Not a big deal up close but distracting at a distance.There is an engraved 0-34mm scale on the side of the flashlight, which might be of use if it was accurate. But it isn't, according to three steel rulers and a caliper gauge.For the advertised price this light is perfect for my needs, but it could be improved.

Ideal for detecting fluorescence in minerals and gemstones, as well as checking for authenticity in banknotes and other items.

High-quality construction can make it resistant to wear and tear, which is crucial for tools used frequently in various environments.

The YZYOE LED Three Light Source Jade Identification Flashlight seems like a practical and versatile tool for professionals and enthusiasts alike.

The media could not be loaded. So this is a economy flashlight with three different types of LEDs built in the head. The light is capable of generating a cool white beam a warm white beam and a 365 nanometer UV beam otherwise known as black light. The black light is useful for currency examination detecting hidden stains in carpet and bedding and some people use it for scorpion hunting which sounds dangerous and I would never do that. Oh and also for looking at certain types of rocks or gemstones where UV or black light is required.Overall I'd say it's a functional economy flashlight with a meh battery. I'm going to capacity test the battery and I'll come back here and post a photo.EDIT- The included battery is not 3000mAh it's 1997 mAh

It works, but it doesn’t indicate that it’s ever charged. The little charger stays red forever but it kind of works so I guess I’ll keep it not happy.

Don't get this when you're looking for a "flashlight" - i.e. something to help you see in the dark. This is a light source for identification of Jade and other translucent minerals or materials. While the 3 LEDs have small individual reflectors, the effect of those is limited by all light going into a conical tube which can be placed up against a piece of mineral that hid being investigated. There is an extra push-in tube that reduced the light exit opening even more. Whether this will work for you, depends on whether the white, yellow and UV LEDs are what you need.The light is a bit bulky, and comes in an even bulker case (which you obviously don't have to use). It is powered by a standard 18650 LiIon battery and comes with a charger for that. Based on other comments about that charger, I have not tried it and will use my trusty NiteCore charger instead.The side of the housing has a 34mm ruler engraved.Operation is pretty simple: after inserting the battery (making sure it's charged), fully depress the tail cap switch to turn it on or off. Once on, a gentle push on the switch will change the active LED. If you need a smaller opening for the light, unscrew that piece from the lanyard and push it in the front (it does not screw in, the rubber O-ring holds it in place).

Unclear instructions for use and the lights do not work on it at all

It's nice to have the uv and visible light spectrum's in one light. I think the beam pattern could have been better. The pinpoint adapter really has no use for me. It doesn't serve much of a purpose. Build quality is good though and the rechargeable li-ion battery is a great bonus.
