UV Flashlight FAQ
Why is a UV flashlight more effective for charging glow-in-the-dark paint than sunlight or regular lamps?
A UV flashlight emits concentrated UV-A light (around 395 nm)—the exact wavelength that phosphorescent pigments absorb most efficiently. This means you get a faster, deeper charge and brighter, longer-lasting glow than with diffuse sunlight or standard LED/indoor lighting. Simply hold your UV flashlight close for 10–30 seconds, and you’ll achieve a peak glow in seconds.
How long does it take to fully charge glow-in-the-dark paint with a UV flashlight?
With a high-power UV rechargeable flashlight, most glow-in-the-dark surfaces reach a full charge in just 10–30 seconds of direct exposure. For thicker projects—like deep resin pours or multilayer murals—boost your UV light charging time to 45–60 seconds to ensure the phosphors absorb maximum energy.
Why is my glow-in-the-dark paint glowing weaker than usual?
A weak or discharged UV flashlight battery often delivers insufficient UV-A output to fully charge the phosphorescent pigments. Replace or fully recharge your UV flashlight batteries to restore the intense glow you expect.
How long does glow-in-the-dark art glow after a full UV flashlight charge?
After a 30–60 second charge with a high-power UV rechargeable flashlight, most strontium aluminate glow art will glow for 8–12 hours, then continue to emit a faint afterglow up to 24 hours.
