Replace older light bulbs, particularly incandescent light bulbs, with more efficient LED light bulbs. A typical incandescent light bulb requires 75 W while an LED only requires 9 W. LEDs cost more in the short term, but if you have the opportunity to replace any incandescent light bulbs you may have, it will lead to significant future savings.

An LED bulb's energy utilization is about 90% lesser than that of an incandescent bulb. Since the incandescent bulb requires heat to generate light, it uses more energy. Below is a table showing the LED equivalent of various incandescent watts. LED lamps are made up of clusters of light-emitting diodes (LEDs). As they are so small, LED lamps come in all shapes and designs.British thermal units (BTU) are a measurement of heat used as part of the Imperial and US customary units of measurement. It is defined as the amount of heat that is required to increase the temperature of 1 pound of water by 1 degree Fahrenheit. Heat is a type of energy, so BTU can be directly compared to other measurements of energy such as joules (SI unit of energy), calories (metric unit), and kilowatt-hours (kWh). LED tube lights use between 40 and 50% less energy than fluorescent tube lights, which is of course comparable to CFLs that utilise the same technology. Fluorescent Tube Light Wattage

Let's imagine that you are looking for an extremely bright bulb that emits 1,300 lumens. For an LED bulb, producing 1,300 lumens will require around 15 watts of power. However, for a less-efficient halogen bulb, over 60 watts of power The brightness of traditional light bulbs like the incandescent bulb and halogen bulbs is best measured using watts because its energy consumption transcends its brightness. However, bulbs that use better technology like the LED bulb use lumen as a measure of its brightness because, unlike the traditional light bulbs, an LED bulb's wattage (energy consumption) has nothing to do with its brightness.To explain this better, when your bulb is a 60-watt LED equivalent, it implies that the LED bulb's brightness is equal to that of a 60-watt incandescent bulb. This has nothing to do with the LED wattage but rather its lumen. As a result, you can use an LED bulb of a greater equivalent, such as a 100-watt equivalent, as long as it doesn't exceed the 60-watt energy consumption limit.
