The first time I saw real LED lighting for the home, I was in IKEA. This was about 4 years ago. I was very impressed. These small lights meant to be installed under walls cabinets or in display shelving emitted cold, blue light – just like the inside of a refrigerator. All the same, I was impressed. I thought to myself that it is just a matter of time, this will either fizzle out leaving LEDs to flashlights and kids carnival toys… or this will be brought into the mainstream. The latter is happening. One of the reasons that LED (Light Emitting Diode) lighting is entering the marketplace so slowly is partly due to our own US government – it can take years for fixtures to become UL approved. There is however, the ETL certification from Intertek which allows safe products to enter the marketplace quickly and on a global level. ETL Safety Mark LED lights entering the marketplace now are categorized as low-voltage. What this means is that the fixtures are not directly connected to your household electricity, but rather “Plug and Play”. A transformer is necessary to “step-down” the voltage to a lower level like 12-volts. This transformer is either plugged directly into a switched outlet or hardwired into the home’s electricial system. Then the individual LED fixtures are plugged into the transformer. The Low Voltage lighting family includes Xenon and Halogen.
