Glow In The Dark & Black Light - How are they different
Sunday, August 31st, 2008Hello
A lot of our customers seem to be unaware of the differences betwwen glow in the dark products, and UV Black Light Products. So the following is a summery of the two individual product series.
Glow In The Dark Products (usually contain glow in the dark powder - Pigments), absorb and store light energy, in well lit places, for example outdoors, and inside near fluorescent lighting. Other Sources of lighting, are the sun, light bulbs, UV Blacklight torches, and neon lights.
When The Glow in the Dark product is removed from the light source, for examples room lighting is switched off, the glow in the dark pigments within the glow product, will discharge light energy over many hours; gradually becoming dimmer as time progresses.
As a gereral rule, the larger the glow pigment, the longer and brighter the glow. So some glow products will glow all night long.
UV Fluorescent Black Light Products, (can be true UV fluorescent products using Fluorescent Pigments - Powders) Glow - Fluoresce when exposed to a UV or Black Light source and do not store light energy.
If the UV Fluorescent or BlackLight is switched off or removed from being near the UV Fluorescent Product, the UV Fluorescent Product will cease to Glow - Fluoresce. In other words UV fluorescent products do not store the light energy, but instead release it imediately. To see an example of UV Fluorescent Lighting, go to a night club.
