These lamps are rated for 5,000 to 10,000 lux (or 10,000 Lumens per square foot), with the majority of lamps favoring 10,000 for good measure. This is roughly equivalent to the intensity of sunlight during the afternoon.
How many lumens are in a Lux?
Lumens: The total output of visible light from a light source is measured in lumens. Typically, the more lumens a light fixture provides, the brighter it is. One lux is equal to one lumen per square meter (lux = lumens/m2).

|Old Incandescent Bulbs (Watts)||ENERGY STAR Bulb Brightness (Minimum Lumens)|
How many Lux is a 100 watt light bulb?
To replace a 100 watt (W) incandescent bulb, look for a bulb that gives you about 1600 lumens. If you want something dimmer, go for less lumens; if you prefer brighter light, look for more lumens.
How many lumens do I need for light therapy?
Light Therapy Research
Bright light treatment requires a minimum of 2,500 lux to be effective, and the brightness recommended by researchers and clinicians for most people is 10,000 lux – an amount significantly higher than standard indoor lighting.
Is Lux better than lumens?
1 lux equals 1 Lumen/m2, in other words – light intensity in a specific area. Lux is used to measure the amount of light output in a given area. One lux is equal to one lumen per square meter. … We use lux because it is an efficient measurement for determining what we see as the brightness of a beam.
How many Lux is too bright?
500 lux – Retail spaces should have this as a minimum light level, as should general office spaces. This level should be suitable for prolonged work on computers, machinery and reading. More than 500 lux – If you have an area where intricate work is being carried out, then very high lux values may be needed.
What are acceptable lux levels?
Earlier it was common with light levels in the range 100 – 300 lux for normal activities. Today the light level is more common in the range 500 – 1000 lux – depending on activity. For precision and detailed works, the light level may even approach 1500 – 2000 lux.
What is a 60 watt bulb in LED?

How many lumens does a room need?
As a handy rule of thumb, a sitting room or bedroom will generally require around 10-20 lumens per square foot, while a bathroom or kitchen will need a stronger level of lighting, at around 70-80 lumens per square foot. To work out the lumens you need, simply multiply the square footage of the room by this figure.
How bright should a sad light be?
Typically the recommended intensity of light is 10,000 lux. How much UV light does it release? Light boxes for SAD should be designed to filter out most or all UV light.
Can light therapy hurt your eyes?
