Will his light work to detect tagged US stamps?

The 365nm UV flashlight is more suitable for detecting stamps. Please select a 365nm torch when ordering. Tips: The 365nm violet light is invisible light(our eyes cannot directly observe the 365nm uv light), so people would see that the 365nm light is not as bright as the 395nm uv light. If you want to observe the detection effect more clearly, it is recommended to detect in a darker environment.

How long does the battery last? What type of battery is in this flashlight?

Lithium rechargeable battery 🔋. With medium usage a recharge once every week or two

Will this detect micro chips?

Things to look for that glow under ultraviolet light: Antifreeze Athlete's Foot fungus Banana spots Bank notes Blaschko's Lines Canola Oil Certain body fluids: Blood, urine, or semen Certain rocks: Fluorite, calcite, gypsum, ruby, talc, opal, agate, quartz, and amber Chlorophyll (red) Cotton balls Fluorescent lights Highlighter pens Honey Jelly fish Ketchup Laundry detergent Olive Oil Petroleum Jelly (blue) Rock salt Scorpions Some cosmetics Tonic water Turmeric Vitamins A & B White paper But no microchips.

If the beam is visible, is it really 365 nm?

You should not look directly at the bulb! But yes it is ultra violet, of which the most common (and by far the least expensive) is sold as 365nm. A number of minerals fluoress under that light, but other minerals require a shorter wave uv light and those lights cost numerous hundreds of dollars. This one is a good light if you want the 365 nm wavelength. It works well on, for example, green fluorite.
