Ideal Voltage for LED Kitchen Lighting.
Why is 24V better than 12V?
Led lighting is measured in Voltage, and Wattage. Voltage is the electronic potential of the light, the force being pushed through the light to make it work. Wattage is the measurement of the power of the voltage and the current measured in Amps together.
A 24V light would need to push through 0.5Amps in order to produce 12 Watts. However a 12V light would need to push through double this (1 Amp) to produce the same 12 watts.
Increasing the voltage to 24V reduces the amount of current needed to get the same output. This in turn increases the distance that the light can travel before dimming out. You get a stronger current than with 12V, so can send your lights much further along the chain around your kitchen from the driver source.
Where can I use 24V?
24V is often used in larger projects or renovations, with longer running lights. It is particularly good for flexible strip lighting around the whole kitchen, or 3-6 task spot lights under the cabinets with ½ - 1 meter in between each. If you are thinking of lighting an office, or commercial premises, 24V is often best also. All in all, it is far more efficient and cost effective to use 24V products all round.
What are the main rules?
Usually the most important rule is that the input for led products need to match the output voltage of your power supply being used. So always match 24V lights with 24V driver power supplies, and 12V with 12V if you use this application.
