Are LED lights bad for your eyes?
(CNN) The blue light in LED lighting that is increasingly used in our homes can damage the eye’s retina while disturbing our biological and sleep rhythms, a French health authority warned in a new report..
How many lumens is a 30×40 shop?
30X40=1200sqft X 100 Lu = 120000 /2600 = 46 T8 32W tubes or 12 4 tube fixtures. 2600 lumens per 32W T8 tube is about average.

How many lumens is a car headlight?
700 lumensHeadlights and Lumens: How much light is a lumen? A single car or motorcycle low-beam headlight is about 700 lumens, and typical high-beam headlight is 1200 lumens. Unfortunately some lights only tell you how many watts of energy they use.
How many lumens does a 60 watt bulb?
800 lumensThat takes lumens. Lumens measure brightness. A standard 60-watt incandescent bulb, for example, produces about 800 lumens of light.
How many lumens is considered bright?
100 lumens is considered bright enough for most walkways — including commercial properties. 100 lumens is equivalent to about 20 watts.
How many lumens does a room need?
To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens. A 100 square foot dining room, which needs 30-40 foot-candles, will need 3,000-4,000 lumens.
Is 3000 lumens too bright?
In other words, 3,000 lumens is meant to give a room a brighter light. This is not ideal if you have a small room and it’s a bedroom. You don’t want to blind your eyes when you’re about to go to bed. On the other hand, 2,000 lumens is ideal if you wish to light up a 200 square-foot living room.

How many lumens do I need for bathroom?
The only light will be above the mirror over the vanity. A useful rule of thumb for bath vanities is to use a minimum of two 60-watt incandescent bulbs, which typically produce approximately 800 lumens each for a total of 1,600 lumens.
How many lumens does a LED produce?
Understand Efficacy (Lumens/Watt) This is a measure of how well a light source converts energy (watts) into light (lumens). The old technology of tungsten incandescent bulbs only had an efficacy of about 15 lumens/watt; LED technology can produce about 60 lumens per watt.
How many Lux is a 60 watt bulb?
840 lumensThe 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.
Is 800 lumens bright enough?
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. … Replace a 60W bulb with an energy-saving bulb that gives you about 800 lumens.
Is 800 lumens enough to light a room?
A couple of 400 lumen spotlights would work well, but if you’ve just got the one light source, an 800-1000 lumen bulb will work, too. And like the kitchen, you want a cool temperature to keep you motivated.
Are LED lumens brighter?
This is different than Watts, which measure the amount of energy in a light. The term lumen means “light,” which makes sense when you understand what this measures. In other words, lumens measure the amount of light your LED light puts out. The higher the lumens, the brighter the light will be.
