About this deal

For decades, we’ve been buying light bulbs according to wattage. But as energy-efficient, low-watt light bulbs like CFLs and LEDs have become readily available, watts have become an unreliable metric for selecting bulbs. Instead of focusing on wattage, which measures power or energy use, manufacturers are indicating the brightness of their energy-efficient bulbs according to lumens, which measure light output. So while we may be accustomed to shopping for bulbs according to wattage, lumens are actually a more accurate measurement of how bright your light will be. Converting Lumens to Watts With both filament and LED bulbs available from this brand - as well as dimmable, smart and colour changing options - you can find affordable Energizer lighting solutions from B&M for almost any fitting. Everyday Light Bulbs How many lumens are in a watt? Because lumens measure brightness and watts measure energy output, there is no simple method for converting wattage to lumens. With energy-efficient lighting like LEDs and CFLs, how many lumens are in a 60W bulb or 100W bulb depends on the lumen output of the bulb, not its energy use.

Many of these energy saving bulbs use between 85-90% less power than other brands and have a superbly long life, meaning you save even more. Energizer bulbs are perfect for households who like to keep an eye on their power usage - whether to save money or to improve their impact on the environment.
