How long does the self-luminous effect last for Glow in the Dark stickers?

Glow in the Dark stickers emit light after being exposed to a light source. Their glow duration depends on the strength and length of the charging period. This article explains how long the glow lasts and how to achieve the best luminous performance.

Glow in the Dark stickers can emit a visible glow for up to 15 hours after being fully charged under a strong light source. Actual glow duration varies based on:

• Light intensity during charging

• Length of exposure

• Type of light (UV light provides the strongest charge)

A full charge under strong UV light yields the longest and most consistent glow.

To ensure maximum brightness and duration:

1. Expose the sticker surface to a direct light source

2. Use strong light when possible (e.g., UV, direct sunlight, bright LED)

3. Allow sufficient charging time

4. Avoid charging through reflective or opaque surfaces

The luminous material stores the light energy and releases it gradually in the dark.

For best results:

• Use strong UV light for the fastest and fullest charge

• Allow longer exposure for extended glow time

• Ensure the sticker surface is fully exposed to the light source

Weaker or indirect lighting (e.g., indoor ambient light) will still charge the stickers, but the glow may be shorter or less intense.

• Maximum glow time: up to 15 hours after full charge

• Glow intensity gradually decreases over time

• Stickers can be recharged repeatedly with no performance degradation

Glow in the Dark stickers can maintain a self-luminous effect for several hours and up to 15 hours under ideal charging conditions. Longer and more intense exposure to strong light—especially UV—results in a brighter and longer-lasting glow.
