If I have two light fixtures mounted on a wall 40 ft apart and 14 ft above a 80 x 30 concrete apron, what watt?
what wattage bulb and fixture do I need to be able to read a newspaper?
Hey, Wolf. The answer is “it depends”. There are 3 problems that need solved, as follows:
Problem 1: It depends on how old those eyes are. If you are 50-ish, you will probably need about 50 or 60 footcandles (fc) to read that newspaper. If you are a little younger, you may get away with 30 or 40 footcandles. I personally need the 50 or 60 fc.
Problem 2: You apparently have a large area to cover — 80′ x 30′. That’s about 2400 square feet. The light is not really distributed evenly. It will be brightest right under the lighting fixture — maybe 80 fc. Closer to the walls, it may be 20 or 30 fc. If the walls are a dark color, it absorbs the light, and it will be darker by the walls — maybe 10 or 20 fc. If the walls are painted a light color, the light will reflect downward, and the lighting levels will be higher — maybe 30 or 40 fc. So BIG Question: Where are you going to read that newspaper?
Problem 3: The 14′ ceiling is a problem. It is a bit high for light to “punch down”. It would cost a lot to put enough lights up in your facility at 14′ to punch down 50 fc. You may be able to suspend the light fixtures down a bit to maybe 8′ or 10′ height, and that could help.
Now to give you the answer that you are asking for:
You are probably going to need about 0.5 Watts to 1.0 Watts per square foot to properly light that facility with 30 to 50 fc. So you will need probably 1200 Watts to 1500 Watts or more to get adequate lighting. That should get you lighting levels of about 30 fc.
You will probably be better off with the Metal Halide Lighting system, as it is a “white light” (vs the yellowish High Pressure Sodium (HPS lights)), and will provide more punch to get the light down 14′. The Metal Halide comes in 400 Watt lamps and 575 Watt lamps. This is the same lighting they use in baseball and football fields. You could probably go with two of the 575 Watt Metal Halide single fixtures, or maybe two 400 Watt double fixtures (two lamps per fixture), so four 400 Watt bulbs, and directed in 4 separate directions for better light distribution.
You could look at the T8 or T5 Fluorescent fixtures, but I think they lack the punch to get the light down 14′.
BTW — don’t let them stick you with the High Pressure Sodium Lighting (HPS). It has a yellowish hue to it.
My suggestion:
Go with the two fixtures with four 400 Watt Metal Halide lamps. It will give you better light ditribution over the 2400 sq ft. If one burns out, you still have three others operating to provide light.
To take care of that reading the newspaper thing: Look into some added “task lighting”, or basically one or two 120 volt plug in desk lamps. Probably a 100 watt lamp, close to where you read the newspaper and diagrams, etc. They can be placed right over where you are reading without trying to get the entire space up to 50 fc which could be expensive. The task lighting will provide 100 fc or more, and can be directed to the work and desk areas where light is needed most, and where you read that newspaper
.
Sorry for the long-winded answer.
