Does it Work?

The material that makes Brightec glow in the dark is a basic mineral that is mined from the earth and treated chemically. It has the unique ability to absorb light and then reemit it. Think of it as a light sponge; it will absorb all it can, glow strongly at the start, then less and less as it gives up its charge. You can recharge at any time and the process starts all over again. Full charge can be achieved in five to fifteen minutes by exposure to almost any light, with a brighter light being the fastest way to achieve a full charge.

Very low light sources may take Brightec longer to charge and may not provide a full charge.

Brightec® patented technology enables the printing of high performance glow-in-the-dark images. Unlike typical yellow and green glow-in-the-dark products, Brightec® film has a pleasing off-white appearance providing unmatched photographic quality prints by day and amazing graphic details by night.

The relevant factors for measurement of luminescence are 1) the intensity of the luminescent effect and 2) how long it lasts. The intensity corresponds to the impression of brightness perceived by the human eye and is measured in mcd/m2 (millicandela per square meter). The duration of the afterglow is benchmarked at 0.32mcd/m2 (100 times the visibility limit of the human eye). The following table compares Brightec® films versus typical consumer “glow-in-the-dark” products.

PRODUCT	AFTERGLOW in mcd/m2(1)
	3 min(2)	10 min	30 min	60 min	90 min	time to reach 0.32 mcd/m2
Brightec Film	185	50	17	9.0	6.0	12 hours
Typical Commercial Glow-in-the-Dark Vinyl	18	5	1.7	0.9	0.6	4 hours
Brightec is the whitest, is 10 X brighter... and lasts longer

_{(1) Please note that afterglow duration depends on a number of variables, such as charging time, light source, distance of product to the viewer, light level environment, adaptation of the human eye to the dark.
(2) Samples were exposed to daylight for 5 minutes. Measurements were made with a luminance meter (Minolta LS-100) placed 10 inches away from 2" by 2" samples.}
