We all know how much light a 60-watt bulb will produce. 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; 60-watt incandescent bulb = 800 lumens; 100-watt incandescent bulb = 1600 lumens; New Labels Shop for 75-watt incandescent bulbs now! Lumens Incandescent light bulb (watts) Fluorescent / LED (watts) 375 lm: 25 W: 6.23 W: 600 lm: 40 W: 10 W: 900 lm: 60 W: 15 W: 1125 lm: 75 W: 18.75 W: 1500 lm: 100 W: … For example, suppose you have a parking lot light that uses a 250-watt metal halide HID lamp. In the table below you can easily see how much 75 watt in lumens is and which alternatives you can choose. But many of us do have some idea of how bright a 100-watt bulb is. Summary: Lumens are not Watts. Watt is a unit of measurement for power draw or the amount of electricity the light bulb consumes. Leave your comment or question in the area below. Lumen outputs can vary per 4’ fluorescent bulb depending on the type, wattage and manufacture. Generally, a 60-Watt incandescent bulb emits an average of 800 Lumens. With the introduction of new energy-saving technologies such as LEDs, power usage is no longer relevant or indicative when looking for the brightness of a light. In the past, if you wanted a brighter bulb you’d simply choose one with more Watts. The brightness, or lumen levels, of the lights in your home may vary widely, so here's a rule of thumb: To replace a 100 watt (W) incandescent bulb, look for a bulb that gives you about 1600 lumens. The average efficacy rating for a halogen bulb is 18.4. Bulb Type 450 Lumens 800 Lumens 1100 Lumens 1600 Lumens 2600 Lumens LED 6W 10W 13W 18W 24W CFL 9W 14W 19W 23W 40W Halogen 29W 43W 53W 72W 150W Incandescent 40W 60W 75W 100W 150W As an at a glance reminder, here are two examples: What are the Lumens of a 60 Watt bulb? Lumens let you buy the amount of light you want. The number of Watts is not a good way of comparing LED bulbs to Incandescent bulbs because they consume a lot of power (watts) that do not convert to light (Lumens). So you can calculate how many lumens the new LED lamps should have based on your previous lighting. Think Lumens, Not Watts: Buying Light bulbs in the 21st Century, Use our Bulb Finder to Shop by Bulb Shape, To replace a 100-watt incandescent bulb, look for a bulb that gives you, Replace a 75W bulb with an LED bulb that gives you about 1100 lumens, Replace a 60W bulb with an LED bulb that gives you about 800 lumens, Replace a 40W bulb with an LED bulb that gives you about 450 lumens. A 75W bulb gives you 1100 lumens. That surplus allows you to choose an LED with more Lumens, meaning a higher wattage equivalency. Watt-to-lumen conversion chart. watts X efficacy = lumens. 75-watt bulb produces 1,100 lumens of light; 100-watt bulb produces 1,600 lumens of light; 150-watt bulb produces 2,600 lumens of light; These measurements are based on traditional incandescent light bulbs. The simplest way to measure the efficiency of an LED light bulb is to calculate its lumens to watt … A compact fluorescent light can produce 50 to 75 lumens per watt, and LED lamps produce 50 to 100 lumens per watt. (Sodium vapour lamp ) 80 lumens /watt. Wattage is still important, but the rise of LEDs with their drastically lower power consumption, it’s becoming a less important factor. Learn more about lumens vs wattage of lights. With an efficiency up to 80% higher than similar output incandescents, it is certainly safe to say that LED light bulbs, like these 75-watt equivalent, use less energy than similar incandescent bulbs. But why would you want a brighter bulb? I say average because the rating fluctuates with the amount of heat produced by the bulb and this affects the efficacy. The formula for calculating the lumens produced by a bulb is a simple one. You may love the cheery glow of that incandescent bulb but the bottom line of your household budget may not have that luxury. A standard 40-watt (40W) bulb is equal to 400+ lumens. To choose a light bulb with the right brightness, think lumens, not Watts. A typical 40 watt incandescent bulb puts out about 475 lumens. This is where wattage equivalency comes into play. LED Lamp —— 90 to 100 lumens /watt. Many consumers buy LEDs based on the assigned wattage equivalency, but LEDs use far less wattage than their CFL, halogen, and especially their incandescent counterparts. For example, a 14-watt LED may be able to give out the same amount of light as a 100-watt incandescent bulb (about 1600 lumens). A 100-watt incandescent bulb gives off 1,600 lumens. It’s time to clear up some common misconceptions about the relationship between Watts and Lumens. The two most common types are 40-watt, 4-foot (1.2-meter) lamps, and 75-watt, 8-foot (2.4-meter) lamps. LED bulbs that have the same wattages might not necessarily have the same lumens ratings. But you don’t need the light in all directions; you only need the light down on the surface of the ground. Lumens vs Watts. Brightness: 945 Lumen; Estimated yearly energy cost: $1.51 (based on 3-hours/day, 11/kWh, costs depend on rates and use) Life: 22.8-year (based on 3-hours/day) Light appearance: 2,700K (soft white) Energy used: 12.5-Watt (equivalent to a 75-Watt standard incandescent light bulb) Lumen per watt: 75 They really have no relationship except for the specific item (bulb or LED). Common terms are "soft white 60," "warm light 60," and "60 watt replacement." LEDs are a money-saving answer to a costly energy question. You would probably want to choose an LED bulb that uses 8 to 12 watts and has a lumen rating of 800 to get the same illumination. Dimmable Globe LED Bulbs Designed for bathroom vanities or anywhere a globe bulb is required, these bulbs produce light equivalent to a 40-watt incandescent bulb, yet only consume 10 watts of power. 16 to 21 lumens per watt. Watts to lumens calculator Lumens to watts calculation formula. Watts measure the amount of energy required to light a product, whereas lumens measure the amount of light produced by the product.
