LED lighting uses solid state (electronic) devices to produce light, rather than by heating a thin wire (incandescent) or creating a electrical discharge in a tube (fluorescent). The technology has been around for many years, but light output, cost and colour had always been the thing that has prevented its widespread adoption for general purpose lighting. Today, good quality, general LED lighting is becoming possible on a realistic budget.
LED has always been fantastic solution for accent/highlight applications where a small light source is needed to illuminate a feature in a room. These days It is also very good at illumination over larger areas and, as LEDs can be arranged in spotlights, in linear strips or even in circles and irregular shapes, difficult areas can be covered in this way.
Mains dimmable LEDs have also become a reality for replacing halogen lamps, in both spotlights and conventional bulb shapes.
FlexiDim dimmer modules support trailing edge, as well as leading edge operation. They also have a profile that has increased resolution at lower levels, which provides finer control of LED lamps. As there is no residual current through the lamp to power the dimmer circuitry, they will control circuits of 1 single lamp perfectly.
Other types of LED
A common type of LED is the 350mA / 700mA / 1050mA constant current device combined in Red,Green, Blue sets allowing colour changing (by varying the proportion of each colour into the mix). Make sure the driver you use matches the current rating of the LED.
Another very popular LED type is linear tape. This is flexible and has good light output, whether as a single colour or R,G,B,W (Red, Green, Blue, White) which allows colour changing.
Broadly speaking control falls into two type: DMX or 1-10V. We prefer DMX, as 1-10V tends to have a poorly defined (and often higher) minimum brightness.
