Application and Dimmability

Applications of LED light bulbs

LEDs do not necessarily require transformers  for their application. LED light bulbs  running at mains already contain a chip creating the necessary Voltage and current for the LEDs, so they can replace traditional light bulbs with a simple twist and turn movement. LED light bulbs working at lower Voltage, usually 12V or 24V do require a transformer . If you wish to apply low voltage LED lights, you will need an LED suitable transformer . Applying the right transformer with your LEDs is crucial not only from the point of view of operating the lights but keeping their expected lifespan. Since the variety of solutions is nearly endless, you have to check with the distributor or the technician for the suitable transformer.

Dimmability

Dimming is one of the last problems solved for LEDs . Originally they were not dimmable with the same systems used for halogen lights. With the latest technologies dimmable LED lights  have become available with most existing systems working with a turn or slide of a knob (TRIAC dimmer). Latest technologies – less available on the market at the moment promise to solve the problem fully, and create LED lights working with all existing dimmers, but this technology called RAIS is still expensive and unreliable at the moment.
