What light source do the GLO-TOOB’s use?
The GLO-TOOB uses Light Emitting Diodes, or LED’s, as they are more commonly known.
The LED is a far more efficient light source than bulb technology. It has many, many more
hours of operation compared to a bulb – typically 100,000 hours of run-time compared to
a few thousand hours for a bulb. It is a solid molded light source, and therefore does not fail
due to shock i.e. it will not break when it is dropped, whilst a bulb usually does. It is a cold
light source, while a bulb can become so hot, it can burn a surface it comes into contact with.
Although it may not offer as much intensity sometimes as a bulb, it drains far less power from
the power source – battery for example, and therefore usually runs longer on the same power
source as a bulb would.
