Detecting scorpions, authenticating currency, ID cards, and passports are just a few of the blacklight flashlight applications. This multi-functional device can also act as a nail dryer.

Lightweight, not blindingly bright but bright considering the size. Batteries seem to work for a long time. ### ⭐⭐⭐⭐⭐ Review *by M***M on 24 January 2025* Small and fits right in the glove box, works great for it's purpose and was a decent price. ### ⭐⭐⭐⭐⭐ Review *by M***O on 16 October 2021* This light put out more UV than my older multi led light. It charged up my glow in the dark fishing jigs in seconds and easily detected leftover leak detection dye from an automotive ac system under daylight conditions . The aluminum body and machined threads are high quality and the lens is recessed to help prevent scratches. The design does a good job of dissipating heat however I am not sure what the lens material is as I do not wish to go that far with the disassembly. On the visible part of the internal curcuit board there appears to be some excess solder flux leftover from assembly and circuit board breakouts are a bit rough. On my example one of the breakout points has a slight interference with the cap threads but that's just me being really picky and does not hinder function. Nothing a quick pass with a file can't fix, especially important for someone with my level of ODC. Also, the spring steel pocket clip can be reversed or removed if needed. I put some dielectric grease on the cap threads and o-ring seals, put one in my tackle box and the other in the garage. I have no reason to believe these lights will not serve me for years and for the price I don't think it can be beat. ## Frequently Bought Together - GearLight UV Black Light Flashlight S100 [2 Pack] - Mini Blacklight Ultraviolet Pen Lights for Leak and Hotel Inspection - Pet Urine, Bed Bug, Scorpion, Stain, and Dye Detector - LE LED Pen Flashlights, Lightweight, Mini, Waterproof Pocket Flashlight with Clip, 2 Pack Small Flashlights for Inspection, Work, Emergency --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/255787507-gearlight-uv-black-light-flashlight-s100-2-pack-mini-blacklight](https://www.desertcart.tn/products/255787507-gearlight-uv-black-light-flashlight-s100-2-pack-mini-blacklight) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-04-25*
