(Watts measure energy used.) A watt measures how much electricity is being used by an item. The average efficacy rating for a halogen bulb is 18.4. However, wattage is not a measure of brightness at all! We used the figure of $5.00 (for a 60 watt equivalent LED bulb) as an average among lighting retailers. So when buying your new bulbs, think lumens, not watts. Let’s use a better measure than lumens. Type of bulb: 200-300 lumens: 300-500 lumens: 500-700 lumens: 700-1000 lumens: 1000-1250 lumens: 1250-2000 lumens: Incandescent: 25-30 watts: 40 watts: 60 watts: 75 watts: 120 watts: 150-250 watts: Halogen: 18-25 watts: 35 watts: 50 watts: 65 watts: 100 watts: 125 watts: CFL: 5-6 watts: 8 watts: 11 watts: 15 watts: 20 watts: 20-33 watts LED: 2-4 watts 3-5 watts: 5-7 watts: 8-10 watts: 10-13 watts: 13 … One of the better CFLs on the market, the GE Reveal Bright from the Start light bulb, uses 15 watts to produce 740 lumens. 28 Watt LED Bulb - 4 Foot T8 Lamp - 3,000 Lumens - Replacement or Upgrade for Fluorescent Light(-Heavy Frost-110-277 VAC) Requires no ballast for operation. Lightbulb brightness in general is measured in lumens (not watts). Bulb manufacturers include this information and the equivalent wattage right on the packaging. watts X efficacy = lumens. Lumen output is 120 lumens per watt for a total of 3000 lumens per bulb. Lightbulb brightness in general is measured in lumens (not watts). A guide figure for an incandescent bulb is 10-12 lumens per watt for ordinary incandescent, 15 lumens per watt for halogen type. That bulb has an efficiency of 49.33 lumens per watt. Over the years, advances in technology have brought about innovations in how to light our homes and commercial buildings. When you’re shopping for lightbulbs, you can choose your next lightbulb for the brightness you want by comparing lumens instead of watts. A lumen is a measure of the amount of brightness of a lightbulb -- the higher the number of lumens, the brighter the lightbulb. Common terms are ‘soft white 60,’ ‘warm light 60,’ and ’60 watt replacement.’. When trying to figure out light bulb brightness, it's important that you understand the difference between lumens vs watts. But the brightness of new CFL and LED lightbulbs are measured in lumens, not watts, so here’s a handy chart to help you do the conversion. Watts measure the electrical energy required to light a bulb, while lumens are a measure of the brightness of the light produced. WHAT’S A LUMEN?

Watts (Incandescent bulbs) Lumens (CFL, LED or Halogen) 40: 450: 60: 800: 75: 1,100: 100: 1,600: 150: 2,600: Source: Energystar.gov. Now we have compact fluorescent lamps (CFL) and light emitting diodes or LED for short. There are many variables, so lets dig in! We are going to tackle the question which light bulb type reigns supreme? That 250-watt bulb outputs roughly 14,000 lumens (on average) in all directions. Do you see what I'm getting at here? We all know how much light a 60-watt bulb will produce. Keep in mind that there is no suitable conversion method to transform watts to lumens or vice versa. The formula for calculating the lumens produced by a bulb is a simple one. Watt is a unit of measurement for power draw or the amount of electricity the light bulb consumes. 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. But you don’t need the light in all directions; you only need the light down on the surface of the ground. The brightness, or lumen levels, of the lights in your home may vary widely, so here’s a rule of thumb: The easiest way to figure out what bulb you need is by using an incandescent/LED conversion cart. The more recent prototype high brightness LEDs are delivering up to 200 Lumens per watt but the current production LEDs are closer to 120-130 lumens per watt. Most of us have a preconception of how bright a 100-watt incandescent bulb is even though this can vary tremendously between soft white and clear glass bulbs. However, because lumens per watt vary for both incandescent and LED lights, it's easier to use a wattage-to-lumens comparison chart. You can also look for an RAZORLUX qualified bulb that is labeled as equivalent to the incandescent bulb you are replacing. On the opposite spectrum, that same light bulb painted black gives off no lumens at all. 60-watt soft white incandescent light bulb. When you're shopping for lightbulbs, you can choose your next lightbulb for the brightness you want by comparing lumens instead of watts. Let's use a Sylvania 72 watt quartz halogen frosted bulb for an example. You should look for 450 lumens if you need a 40-watt bulb; You should look for 800 lumens if you need a 60-watt bulb; You should look for 1,100 lumens if you need a 75-watt bulb It’s easy to locate the wattage and lumens of light bulbs while shopping, since it’s now standard to print this information on the “Lighting Facts” section of the bulb’s packaging—similar to the nutrition facts on a package of food at the grocery store. To put it another way: A specification in lux tells you how many Lumens (total light output) you need given the measured area you are trying to illuminate. More lumens means it’s a brighter light; fewer lumens means it’s a dimmer light. However, not all 60-watt bulbs are alike! 710061,China. This means that a 60-watt vintage bulb will give you about 300 lumens when a standard incandescent 60-watt bulb will give you 800 lumens. If you want something dimmer, go for less lumens; if you prefer brighter light, look for more lumens. As a rule, you'll replace a standard 75-watt bulb with an energy-saving bulb of about 1100 lumens.

Meanwhile, a 60W CFL will give off nearly 3,000 lumens. In reality though, most people are looking for a cheap $2.50 bulb or even less. In the beginning, all we had was the standard, incandescent light bulb. Common terms are ‘soft white 60,’ ‘warm light 60,’ and ’60 watt replacement.’. The Lighting Facts are a great help to light bulb shoppers, since it makes it much easier to predict exactly how the bulb will perform, and whether it’s right for you and your specific needs. If you want something dimmer, go for less lumens; if you prefer brighter light, look for more lumens. So a 60W tungsten bulb may emit 800 lumens of light, but a 60W LED light could release over 2,400 lumens per bulb. When we think of the different levels of brightness given off by light bulbs, most of us will come up with four numbers: 45, 60, 75 and 100. So if a package for a lightbulb says the bulb uses 60 watts, or 60W, it means that that bulb will use 60 … BUY LUMENS, NOT WATTS In the past, we bought lightbulbs based on how much energy, or watts, they use. Bulb manufacturers include this information and the equivalent wattage right on the packaging. A standard 60-watt incandescent bulb puts out about 820 lumens. On average, an incandescent bulb produces around 14 lumens per watt, compared to 63 lumens for energy saving compact fluorescents (CFL) and 74 for LED bulbs. Since most household bulbs are 40W, 60W, 75W or 100W, you may be able to memorize their equivalent lumens. We use the United States Post Office and FedEx for our shipments. For example, a correct replacement for a 60w incandescent bulb would be a 15 watt CFL bulb (60 * 1/4 = 15). Lumen outputs can vary per 4’ fluorescent bulb depending on the type, wattage and manufacture. "Silent Night" Lighting Vibes for this Christmas Season. Wouldn’t it make more sense to buy lights based on how much light they provide? This new label will make it easy to compare bulb brightness, color, life, and estimated operating cost for the year. For example one brand's 9 Watt LED bulb may emit enough Lumens to replace a 60 Watt incandescent but another brand may need to use a less efficient LED, lets say 12 Watts worth to create enough lumens to replace a 60 Watt bulb. On the low end, replace a 40-watt bulb with an energy-saving bulb of about 450 lumens. Say you normally use a 60-watt incandescent bulb, for example. 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 She has worn many hats with us over the years, developing an extensive knowledge of lighting and the lighting … A lumen is a measure of the amount of brightness of a lightbulb — the higher the number of lumens, the brighter the lightbulb. So, you need to determine adequate lumens to pick out the right bulb. A long life bulb with the same wattage will likely only output around 500 lumens due to its less resistant and thicker filament. Clearly, in the case of measuring LEDs, lumens are the better measurement. For Alaska/Hawaii, the base rate is $27.59 and surcharges may apply for larger orders. For example, if you typically purchase 60W incandescent bulbs, which produce about 700-800 lumens, consider purchasing a lower energy alternative like a 42W halogen bulb, 12W CFL, or even a 10W LED bulb to achieve the same brightness. Relationship between Lumens & Lux. I find that a directional led at 450 lumens matches the task illumination of a 100 watt incandescent, and assign this condition B4, a Brightness Number of 4. And while a standard 60-watt incandescent bulb has 870 lumens, a halogen bulb of the same wattage has 960 lumens and lasts three times as long! 150. That translates to a 60-watt incandescent bulb producing 13.67 lumens per watt. The Lighting Facts Label will help. A 100-watt incandescent bulb gives off 1,600 lumens. Estimates of bulb lifespan are projected, since it would take about 6 years of continuous lighting to test. Normally the watts is a measure of how many watts of electicity a bulb uses, so a 60 watt bulb uses 60 watts. CFLs and LEDs use much fewer watts than incandescents with the same brightness. Lumens let you buy the amount of light you want. So from here, we loosely predict that a 100-watt bulb can be brighter than a 60-watt bulb because it takes up more energy per second. This is so much more efficient considering that the 100 Watt incandescent bulbs put out roughly 17 lumens per watt. Several years ago, wattage used to be the measure of the brightness of light bulb. This article equates 1600 lumens to a 100 watt incandescent bulb. For example, if you typically purchase 60W incandescent bulbs, which produce about 700-800 lumens, consider purchasing a lower energy alternative like a 42W halogen bulb, 12W CFL, or even a 10W LED bulb to achieve the same brightness. Though the two terms may be easily confused, it’s relatively easy to understand lumens and what to look for when shopping for light bulbs. I say average because the rating fluctuates with the amount of heat produced by the bulb and this affects the efficacy. We never guarantee a certain method for any order unless it is an express order. Things has gotten more efficient now that wattage is simply how much electric power your light bulb consumes. When you’re shopping for lightbulbs, compare lumens to be sure you’re getting the amount of light, or level of brightness, you want.
