Ideal for murals, canvases, resin pours, and multi-layer glow projects. Features: 21 UV LEDs for a wider, stronger beam spread 395nm wavelength - optimized for strontium aluminate glow pigments Even coverage for paints, powders, resin, and fabric Durable aluminum alloy body Lightweight and workshop-friendly Battery powered - requires 3 × AA batteries (not included) Why it’s great: Faster glow activation on medium to large projects More uniform charging than small LED flashlights Reliable tool for artists, DIY creators, and workshops🔋 Pro Tip: If your pigment & paint isn't glowing as strongly as before, it's not the pigment - it's the batteries. Weak batteries reduce UV output, which directly affects glow performance.
