How long does the Glow Last?
« on: September 07, 2017, 07:01:47 AM »
We have been asked this question countless times and it is a rather tricky question as we are not sure whether you are referring to the length of glow (Glow Time) or the lifespan of the product.

So I will answer the question in two parts.

1) Lifespan

Glow products can last for many years. We have paintings in our shop that are still glowing for the past 20 years with no signs of fading. We also have some paintings done outdoors which faded away in a few months. So I guess the environment plays a huge part.

The Glow effect can last for years. The secret to making it last as long as possible on the application method and what is used to protect the painting or glow surface. For example, adding a clear coat of UV protection for outdoor paintings, could add a few years to the lifespan of the glow painting.


2) Glow Time

Glow Powder is the raw material used to manufacture every other glow in the dark product. Glow time for each product, depends on the amount of raw material (Glow Powder), used in the manufacturing process.

Glow Time depends mainly on the grade and particle (mesh) size of Glow Powder. The higher the grade and the larger particle size of each grade, will glow more brighter and for a longer period.

2) I left the Glow product outdoors the whole day. Why the product does not Glow in the Dark for the time stated  ???

For this we have to look at how Glow in the Dark works. It works by absorbing surrounding light and releasing the absorbed light. Glow in the Dark products need about 30 minutes maximum to get fully charged from surrounding lights. It then takes hours! to discharge the absorbed light. Actual number of hours taken to discharge depends on the product grade.

But what we fail to notice is that the process of charging and discharging is continuous. What this means is that while the Glow product is exposed to light and in a charging state, it is also discharging once it is fully charged and starts re-charging again. Leaving it outdoors under the sunlight just repeats the charging and re-charging process as there is a limit to the maximum level it can be charged. This is the same as charging rechargeable batteries and not using them for a few weeks.

So in conclusion, Glow in the Dark products are best used as an Emergency Lighting Source in the event of a Sudden! Power Failure (Blackout). With the Glow time varying, pay special attention to the word Sudden!! Power failure.
