What are LEDs?

An LED is a semiconductor device that emits a visible light of a certain colour when an electrical charge is applied. They provide a very low heat source with a very long lamp life – around 50,000 hours.

What defines the colour of the chip?
Different material composition of LED Chip materials allow for a single colour from a huge spectrum of colours.

Can an LED chip emit white light?
No

How do we get white light for lighting?
LED Chip manufacturers combine either a blue or UV emitting LED with a yellow phosphor.
They can be used to introduce accents of colour or are ideal in situations where no heat is a requirement such as uplighters and floor washers where little fingers could be burnt. Linear versions can now be used for shelf lighting such as the Contour. They are also more energy efficient than standard halogen fittings which help in our efforts to be greener consumers.

What are dimming LEDs?
LED’s can be easily dimmed but require slightly different equipment and wiring. Most LED’s are 0-10v, this dimming requires a 0-10v dimmer module (which can fit in the JCL wall plates and dimmer plates) rather than a regular dimmer. Secondly 0-10v dimming requires a pair of cable to be connected to the dimmer module.
Some LED drivers allow for the product to be dimmed on regular dimmers, however compatibility with the particular module needs to be checked.
