How many foot candles are in a 100 watt bulb?
Their efficiency is in the range of 4 lumens per watt. This means that a 100 watt bulb will generate 400 lumens – TOTAL. (Here’s the big leap) Now, if we COULD reflect all of that 400 lumens onto 1 square foot we would get a light intensity of 400 foot candles.
How bright is 30 foot candles?
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.
How do you calculate foot candles?
Calculation Cheat Sheet:
- To calculate Lumens (Lux) from foot-candles: Lumens = Foot Candles x 10.76.
- To calculate Watts from foot-candles: Watts = Lumens x 0.001496.
- You can also calculate the number of watts directly from foot-candles by combining both equations & using the following: Watts = Foot Candles x 0.01609696.
How many foot candles is daylight?

When considering illumination an active storage area should be lighted to a minimum foot candle?
What is considered adequate lighting?
Adequate lighting means a light intensity of 20 foot-candles (approximately equivalent to a 60 watt bulb at a clear distance of 5 feet).
What should be the lux level of excavation areas as OSHA?
General Lighting Requirements General construction plants and shops: 10 foot-candles. General construction area: 5 foot-candles. Warehouses, walkways, corridors, exits, and other indoor spaces: 5 foot-candles. General underground work areas, including shafts and tunnels: 5 foot-candles.
What is standard lux level?
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 size company does OSHA apply to?
Businesses with more than 10 employees must maintain OSHA injury and illness records unless OSHA classifies the business as partially exempt. If you have fewer than 10 employees during the year, unless OSHA or the Bureau of Labor Statistics says otherwise, you do not have to keep illness and injury records.
Do small companies have to follow OSHA?
Small businesses with fewer than 10 employees are partially exempt, meaning they are not required to maintain OSHA injury and illness records unless informed otherwise in writing by OSHA or the U.S. Bureau of Labor Statistics.
