Light was about 3" away from stones. 4th picture shows lighting in room. ### ⭐ Wasn't what I was looking for *by R***. on January 3, 2026* I'm sure it is a great product for someone maybe looking at slides in a lab setting but barely highlighted any of my crystals that uv way better off the $10 urine searching one my mom has so to each its own just wasn't a good fit for me πŸ₯° ### ⭐⭐⭐⭐⭐ The long bar light on the side is the correct wavelength to illuminate ringworm! Highly recommend. *by A***S on July 25, 2025* This helped diagnose my child's ringworm on the side of his face. The long blacklight bar on the side is the correct wavelength to cause ringworm to glow green; it has to be this wavelength in order to detect ringworm, other blacklight wavelengths will not work. Doctor confirmed it was indeed ringworm. ## Frequently Bought Together - AAdvance Instruments UV Lamp 254nm/365nm 4W Portable UVC/UVA Shortwave Longwave Lab Batteries Included AI-0UV19 - Glass Backed TLC Classical Silica Plate - Silica Gel 60 F254 2.5 x 7.5cm （80/BoxοΌ‰ - stonylab TLC Developing Tank, Borosilicate Glass TLC Display Chamber Small Dyeing Tank for Thin Layer Chromatography --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/140487181-uv-lamp-254nm-365nm-4w-portable-uvc-uva-shortwave-longwave](https://www.desertcart.jp/products/140487181-uv-lamp-254nm-365nm-4w-portable-uvc-uva-shortwave-longwave) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-17*
