Let’s go through the steps involved when you’re shopping for light fixtures. Remember, an easy way to compare bulbs is to use the government label, which should appear on all bulbs by January 2012. The color is a soft white, which is similar to soft white incandescent bulbs. The energy used is 24 watts, saving you $60 in energy costs and will last for 7 years. For instance, the CFL in the photo on the right says the Sylvania Super Saver CFL is a replacement for a 100-watt bulb with a lumen (brightness) output of 1500. Manufacturers are also changing the look of their overall packaging to help even more. It looks similar to nutrition labels on food and will have more concise information about the bulb’s output and savings (seen in the image on the right). The Federal Trade Commission has worked with manufacturers to develop a new label to help consumers purchasing energy-saving bulbs. 100-watt incandescent bulb = 1600 lumens.With new light bulbs, shopping by lumens will be more important than shopping by watts when choosing which energy-efficient bulb to purchase.40-watt incandescent bulb = 450 lumens.These are the two main factors to keep in mind when you need to put a fresh light bulb in your socket. Lumens refer to the amount of light you can see, while watts calculate the amount of power that gets used up. Lumens vs Wattsīut while lumens tell you how bright your bulb is, watts tell you how high your bill will be. Both lumens and watts are common units in the light bulb space. Before you get completely lost, we need to go over the two basic terms that we’re discussing here. At that point, it was all about wattage and voltage.īut then in 1962, LEDs were invented, and now that we’re firmly in the 2020s, the focus is on lumens. Then we got Edison’s light bulb patent in 1879. We’ve known about static electricity since the 1600s, but Ben Franklin didn’t make the lightning connection until 1759. Electricity has been around for a long time.
