Replacing your average household light bulb has become more complicated over the years. Energy saving technology like compact fluorescent and LED mean you can get a light bulb as bright as your old 60W incandescent that uses, for example, just 8 Watts of electricity.

Understand Watts Watts are a measure of energy consumption. Step 2. Understand Lumens A lumen is a measure of visible light energy. Step 3. Popular Articles. Some of the most energy to light efficient LED bulbs are now reaching over lumens in Energy Star tests. A 40 watt incandescent filament bulb produces roughly lumens.
An equivalent compact fluorescents CFL bulb in light output lumens should consume only around 7 watts and LEDs approximately 6 watts. The colour of light can also affect how bright a light appears, even if the lumens are the same.
Bulbs that are nearer to daylight bluer or cooler in colour sometimes appear brighter than yellower coloured lights. Light colour is measured using a temperature scale called Kelvin K.
For whiter light — more akin to daylight — good for kitchens and workspaces, bulbs labelled between K would be best. Reading lights tend to be marked K these appear much bluer and perceived as brighter. There are many factors that will affect the longevity of a bulb. The heat generated by bulbs can also affect their longevity, even with LEDs which create very little heat when compared to incandescent bulbs.
