On the low end, replace a 40-watt bulb with an energy-saving bulb of about 450. As a rule, you’ll replace a standard 75-watt bulb with an energy-saving bulb of about 1100 lumens. CFLs and LEDs use much fewer watts than incandescents with the same brightness. So then, what’s a lumen? A lumen (lm) is used to measure how much light a bulb emits. Lumens equal brightness watts measure energy used. Here are some lumen per watt (LPW) targets for common. But with LEDs, you’ll need to think in lumens (not watts) when it comes to the amount of light. Definition: The ratio of light energy output (Lumens) to electrical energy input (Watts). You’re probably used to looking at the wattage on the packaging of your incandescent to determine how bright you need the bulb to be. What’s a Watt? A watt (w) is used to measure how much energy a bulb draws (not how bright it is). Topics will include covering the basics (like watts vs lumens down below), what exactly you should be looking for, and why it makes a difference - not just on your wallet but on the environment as well. Over the next several weeks we will be posting various tips, information, and guides to help you understand what you need to know when switching out incandescents and replacing them with LEDs. Watt and lumen units represent different quantities, so you cant convert watts to lumens. But you don’t need the light in all directions you only need the light down on the surface of the ground. That’s where our “Be Enlightened” series shines. That 250-watt bulb outputs roughly 14,000 lumens (on average) in all directions. But thanks to advances in technology, LEDs (light emitting diodes) can now have the same warm glow as an incandescent you just have to know what to look for when purchasing. Your incandescent light has just burned out and now you need a replacement light, but which route should you take? You’ve heard LEDs can help save energy and money, but you’ve also seen how “blue” and dim they can appear.
