Quad Head Torch (In stock)
The Princeton Quad head torch not only looks great but can compete with head torches at almost double the cost. Easy to use and built to last, the Quad has three settings, high, low and flash plus a handy battery meter and, if that’s not enough, the Quad is also waterproof to 1 metre!
What is an LED?
LED stands for Light-Emitting Diode. A diode is a component that allows an electric current to flow in one direction, but blocks it in the opposite direction. Thus, the diode can be thought of as an electronic version of a valve . Circuits that require current flow in only one direction typically include one or more diodes in the circuit design. An LED is a diode which emits light when an electric current passes through it.
The main features of LEDs are:
Very Low Power Consumption - significantly less energy used (and subsequently less wasted) when compared to other light sources.
Long Life - High Brightness LEDs have a long operational life in the region of 100,000 hours, even under extreme conditions.
Robust Construction - As there are no moving parts within the LED, damage from vibration, shocks or knocks is of little concern to the LED application.
Fast Response Times - LEDs have very little time between on and off states. The light output does not need to
