lumens per watt
So what are Lumens? It’s a measurement of light output from a lamp. When a light bulb produces more lumens per watt of energy input, its more efficient. If you’re looking into purchasing a solar power system by switching to high efficiency lighting, such as LED light bulbs the annual cost savings help to decrease the upfront cost of the solar photovoltaic system.
What do you think about high efficiency lighting such as LED technology? Would you buy a light bulb that produced more lumens per watt of electricity used? What is your selection criteria when your shopping for light bulbs?
