How do you installing a ceiling fan on 14 foot ceilings?
Yes. Most ceiling fans have parts that let you either put the fan close to the ceiling (which is typical for an 8' ceiling) or let it hang down farther from the ceiling. All my ceilings are 8' and I have 4 ceiling fans in 4 different rooms and they work good by letting me reduce my AC usage, which is much more expensive.
What is measured in lumens?
Lumens is a measure of light flux, so is independent of the area. It is essentially the amount of light available. So think of a bright light. It has a fixed amount of lumens, regardless of how near or far you are. Lux is the light level at a surface. If you think of a light bulb, the lux will vary with the distance from the light source because the light spreads out. 1 lux = 1 lumen per sq meter. Most light meters read out in lux, which is a measure of the brightness at a surface. You will measure more luxes when you are closer to the bulb, than when farther away. Suppose you are measuring a compact flourescent lightbulb (CFL), which is roughly cylindrical in shape. You use your light meter and read 1000 foot-candles at about 1/2" from the lightbulb. How do you compute the lumens of the lightbulb? (1) Convert the foot-candles to lux: 1000 foot-candles = 10764 lux (2) Compute the area over which that lux value applies. This is roughly a cylinder that is 1/2 inch bigger in all directions from the bulb. So measure the bulb. We are going to convert all of our measurements into metric units. 1/2 inch = 0.0127 meters bulb height = 9 cm or 0.09 m bulb radius = 2 cm or 0.02 m inflated height = h = 0.09 m + 2 * 0.0127 m = 0.1154 m inflated radius = r = 0.02 m + 0.0127 m = 0.0327 m area_of_cylinder = 2*pi*r*(r+h) = 2 * 3.14 * 0.0327 *(0.0327 + 0.1154) = 0.03 m^2 (3) Compute the total lumens of the bulb: bulb_lumens = 10764 lux * 0.03 m^2 = 327.5 lumens. Notes: a) If your bulb is more like a sphere, you should use the formula for the surface area of a sphere rather than a cylinder. b) When measuring the lux or foot-candles of the bulb, you should measure at several locations and average the number. c) If you measure from a large distance away from the bulb, then you can ignore the size of the bulb in your calculations.
Are decibels used to measure light?
Absolutely. Photographic light meters are designed to measure light for photographic exposure (in a film-speed/shutter-speed/aperture combination), but many hand-held photo light meters can measure light in footcandles, which is a common scale. If you look on places like eBay, you can find inexpensive, digital, brand new meters which read out in Lux or Lumens. Some may read in footcandles as well. It's not difficult to convert from one measure to another (there should be internet calculators which would do it easily).
How many people in Kenya can read and write?

What is better 100 or 130 lumen?
Depends. If you're trying to read, 130 lumens is brighter, so it's better. If you're trying to sleep, 100 lumens is dimmer, so it's better.
Does tube lights use less electricity than light bulbs economy wise?
Certain types of bulb use much less energy than others:Incandescent: 10 lumens per wattHalogen: 13 lumens per wattFluorescent (tube): 50-60 lumens per watt (cheap to buy)LED: 50-70 lumens per watt (expensive to buy)Read more: How_do_light_bulbs_save_energy

Where does the term 20-20 vision originate?
Eye charts are designed to be read at a distance of 20 feet (6.09 metres). Those who can read the 20 foot 'line' are said to have 20/20 vision. If they can read the 10 foot line, then they are 20/10, and so on.
