How long do Glow in the Dark stickers glow?

Up to 15 hours after a full charge. How long and how bright they glow depends on the light: longer exposure to strong light, especially UV, gives a longer and stronger glow.


Glow time and charging

Glow in the Dark stickers store light and release it slowly in the dark. How long they glow depends on how strong the light is and how long they charge.

How long do they glow?

Up to 15 hours after a full charge under strong light. The glow is brightest right after charging and fades gradually over time. The actual time depends on:

  • How strong the light is

  • How long the sticker is exposed

  • The type of light. UV light gives the strongest charge.

How to charge them

  • Expose the printed surface directly to a light source.

  • Use strong light when you can, such as UV light, direct sunlight or bright LED.

  • Give them enough time to charge.

  • Don't charge them through reflective or opaque surfaces.

Weaker or indirect light, such as normal indoor lighting, still charges the stickers, but the glow may be shorter and weaker. Read more in what kind of light do they need to charge?
