60-watt incandescent bulb = 800 lumens; 100-watt incandescent bulb = 1600 lumens; New Labels. Common terms are ‘soft white 60,’ ‘warm light 60,’ and ’60 watt replacement.’ By the time you're 60, you need around 100 watts.” As brightness is measured in Lumens, the following will help you choose a bulb with the wattage (or equivalent wattage) that you need.

A 100W bulb was brighter than a 40W bulb but this isn’t always the case anymore.

That being said, keep in mind that too much light or glare can be just as bad as too little light. Dr. Faye says, ''When light glares from highly reflective surfaces, it's fatiguing and especially disturbing for older people with cataracts and retina problems.” So if bright light gives you grief, use a shaded lamp rather than a desk lamp to cut glare and moderate light. Wattage to Brightness Comparison. Lumens to watts calculator Watts to lumens calculation. But all in all, when considering the right light for your eyes, remember: your eyes will tell you what they want. 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. However, not all 60-watt bulbs are alike!

Bulb manufacturers include this information and the equivalent wattage right on the packaging. I document my adventures in travel, style, and food. We recommend using a desk lamp.

But was poor reading light really the cause of our vision loss? 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: 25 W: 2250 lm: 150 W: 37.5 W: 3000 … Later on when many of us got glasses, we even felt guilty about the time we spent under the covers reading bedtime stories by flashlight.

While reading in dim light will have no long-term effects on your vision, it does place an uncomfortable strain on your eye muscles. That bulb has an efficiency of 49.33 lumens per watt. Welcome to my blog. The word “lumen” is the standard term used to describe light output—for example, a candle gives off about 12 lumens, whereas a 60-watt soft white incandescent light bulb produces about 840 lumens. Hope you have a nice stay! ... That 250-watt bulb outputs roughly 14,000 lumens (on average) in all directions. But you don’t need the light in all directions; you only need the light down on the surface of the ground. If the light isn't comfortable, they will show signs of fatigue, like burning, redness, brow-ache, headache, or squinting. 60 Watts: Look for at least 800 Lumens. Avoid reading from a computer whenever possible during your leisure time, or at least dim down your screen to lessen the glare. So, it's not that incandescent bulbs are going away—they are simply changing. Your pupils dilate from the dark when they wander off the page, which can make your eyes become easily fatigued – a reason many of us quickly become tired when reading in bed at night.

It’s also helpful to avoid reading by light that reflects a lot of bright glare, such as from a computer screen. Dr. Eleanor Faye, the ophthalmological director of the Lighthouse for the Blind Low Vision Service, says: ''The eye's need for more light to read by increases 1 percent a year. Energy saving lamps have high luminous efficacy (more lumens per watt). LED Parking Lot Lights - Starting at $139. (The Kindle app for computers and mobile devices does this really well.). Replace a 60W bulb with an energy-saving bulb that gives you about 800 lumens. A standard 60-watt incandescent bulb puts out about 820 lumens. In comparison, a CFL light bulb that also produces 800 lumens only uses 15 watts to power it. Therefore, to reduce the conflict in your eye muscles when you’re completing a high-concentration task such as reading, it’s important to focus bright light directly where it is needed.
