When choosing LED lights, the first thing to consider is what colour or temperature you are after. The colour of your LED is measured in Kelvins. Warm light is represented by a low number and cool light is represented by a higher number.
Do not get your LED light colour confused with the brightness. These are two different measurements. Brightness is measured in Lumens. The higher the lumens, the brighter the light. Most LED lights provide around 85 lumens/watt as oppose to a halogen globe that provides a mere 17 lumens/watt.
Another important specification to be wary of is the amount of Watts that your light expends. This is a direct reflection of your electricity bill and so the lower the wattage, the more energy efficient and cost effective your LED lights will be to operate. One of the primary benefits of LED lighting is the significantly lower amount of watts needed to provide the same brightness of light. Most LED lights use about 10 watts compared to the usual 40-50 needed for a halogen globe.
Energy consumption – the amount of electricity required to operate your light. This is measured in Watts and is a direct reflection of your electricity bill.
Lumens – This is a measure of the amount of light produced
Average Rated Life – Normally measured in hours, this is an indication of the expected life span of your light.
Colour Temp – Measured in Kelvin, this is an indication of the colour of your light whether it be warm (measured in low numbers) or cool (measured in higher number).
