What Is LED & Its Advantages Over Incandescent
Light-emitting diode (LED) is a two-pin semiconductor that emits light. In simple terms this means, instead of converting current into heat with a filament, it converts current into light, removing the need of a filament and the use of heat. This form of light gives LED the advantage over incandescent light as it provides:
- Lower energy consumption
- Longer lifespan
- More robust physical construction, making it safer to use in any application, less harmful on the environment and recyclable
- Brighter output
- Generate little to no heat
The IP rating of a product classifies the degree of a protection the casing/housing of the product has from contact with anything that could cause the product to malfunction or fault, such as water and dust. There are two digits that make up the IP rating of a product, the first digit giving the degree of protection against solid particles, and the second digit giving the degree of protection against liquid access.
- If an item has an IP rating of 44, this means that the item will be protected against solid particles larger than 1mm and splashing water.
- If an item has an IP rating of 67, this means that the item is completely dust tight and can be immersed in water up to a depth of 1m.
So in simple terms, the higher the IP rating to more protected the item is from harmful substances.
Colour temperature in the simplest terms is a measuring system used to determine the ‘visible colour’ of light on a scale measured in degrees kelvin determined by a black body radiator. The scale ranges from the colour of a match flame to the colour of a clear blue sky, where the “yellower” the light the warmer it is and the “bluer” the light the cooler it is.

Lumens & Brightness
Lumens is a unit of measurement that’s describes the total amount of visible light produced by a light source.
Watts is the amount of power consumed by a source in order to produce the lumen output.
The higher the watt rating of a light source, the higher the lumen output that the light source would produce.
