A QUICK GUIDE
Often referred to as Longwave Ultra-Violet or 'UV A'. Blacklights are
a specialised type of lighting unit that generates a safe form of UV light
invisible to the human eye.
The frequency of UV light emitted by Blacklight units (365 nm) is exactly
the right frequency to make UV Revealing products such as STARGLOW UVR
Paints; fluoresce brightly and also energise Glow-in-the-Dark products
so they perform at their best.
Blacklights are considered
safe for use in the home as well as theatres and night clubs etc.
The kind of Blacklight units* sold by GLOWTEC are low-power units and are
the safest of all Blacklight units available commercially.
Besides the wide range of Fun and Artistic applications, there are several
other serious uses that Blacklights are particularly suited to:
UV-LED based Blacklight products are also
classed as safe, providing the LEDs are not shone directly into the
eyes. It is the intensity of light generated by this new
generation of LEDs rather than the UV output, that can be potentially
harmful. The key advantages of this new generation UV-LED based
products, is portability and low power consumption, thus making them a
very popular option.

In plain and simple terms there are three bands of UV light; UV - A, B and
C. The difference between the three is simply the frequency range of
320 - 400 nm
Longwave UV is
widely used for Tanning and Blacklight effects.
280 - 320 nm
The type of
Natural UV largely responsible for sunburn.
200 - 280 nm
Shortwave UV is
completely filtered out by the atmosphere.
The safest form of UV light and often referred to as Longwave UV, this is
kind of UV light generated by Blacklight units (the dark purple fluorescent
tubes) as well as UV LED Torches. It is a safe form of invisible UV light
and is used to energise and activate the STARGLOW range of products (365 nm
to be exact). Most quality sunglasses will protect eyes against UV-A.
Most quality sunglasses will protect eyes against UV-A.
This particular kind of UV is the one that can cause sunburn if over
exposed. It can also be used in the medical treatment of certain
Most quality sunglasses will protect eyes against UV-B.
Totally absorbed by the Earths atmosphere, but widely used as a Germicidal
steriliser in Hospitals. UV-C is source of UV you are unlikely ever to
