Question: are led light bulbs cheaper to run?
Answer: The large variance between an LED bulb and, say, a halogen bulb wattage is the reason LEDs are so much cheaper to run. ... This means that the LED spot uses 90% less electricity to run and therefore it costs 90% less. We have 6W Led bulbs that are replacements for 60W halogen bulbs, again saving 90% energy and cost.
