the lost power is never lost during the heating season, The losses are heat energy and the result is that the heating system runs less.
If you are running AC then the AC operates and does the opposite so the two are fighting against each other and this does waste energy.
There are many published reports that will give statistics on energy consumption but they seldom take this very obvious factor into account in the calculations which are often designed to sell the product.
I worked in the printing industry where color rendition is very important, errors can lead to tons of printed material not being accepted by the buyer, the packaging industry is sensitive for this , they want their products to appear the same , not different as they may look like old products or not represent their corporate color choices well. Kodak yellow is always the same, they dont want variation for example, although kodak is gone for the most part,, You know the yellow to expect ,from memory.
in printing color contracts are signed under standard lighting, these are called contract proofs, the buyer signs off on the color sample and the printer has to keep within certain limits otherwise the job can be rejected at the printer's cost, this is a contract and has a legal aspect involving money so the lighting booth , usually located by the press, is standardized.
in rinting a densitometer is what's used to track differences in color, it reads color spot samples and gives a numeric figure thsi is how a pressman keeps as close as possible to his signed contract proof which is often right there as a comparison on his register table. This is a station where he constantly pulls sheets to check various things including color density. part of his job is to maintain consistency so the printed job is maintaned within specified and measurable tolerances.
the standard is not sunlight but 1000 degrees kelvin which is basically what you get if you have northern light to your back.. this is whiter than sunlight.
sunlight varies, there is more red in the spectrum in evenings and in fall. this also helps trigger plants to flower as well as hours of light. Halide lights are extremely bright and hot, they are often used in places like jewelry stores because they want you to be influenced by sparkle when looking at things like diamonds but not for things like color comparison. its often used for sales.
one thing I dislike about the halides is that if you are to sit near the table, waiting etc and you get the harsh light straight in your eye then it can be quite blinding. If you've ever been flashed by an electric welder then you'll have that as a comparison to how exposure to very bright light can blind you somewhat, at least temporarily. maybe its ok if the fixtures are designed with diffusers or low enough not to get hit straight in the eye.
all this can affect you when you look at the ball as you then see a reflection of the lights above. I was curious how that affected a players decision or if they tried to ignore the image of the light reflected from the balls. The response I got was to try to ignore that and look at the ball, it's not really a reliable way to make any judgement. I wondered if others agree with that.
the lights you choose are of course your decision and some may prefer whiter light or a more yellow shade, like sunlight.
the color of balls and clothing and such will appear different under different lighting conditions but pool players are mainly trying to focus on the position of balls, not their colors.
I have a 3 light fixture over my 10 foot table, it should be 4 so I had to hang it a bit higher. if I sit near the table its in my eyes, fine when playing. I dont really want to spend on new lights but had the idea I might like a nice wood and mica fixture which I could create to fit the surrounding decor which is craftsman style.
I'm not trying to sway anyone else's opinion ( why would I care? ) I am interested in what others like best.
the more pin point our lights are, the harsher shadows will be. I think we will all agree the shadows are of no use to the player,if anythign, an annoyance. the more diffused the lights are, the less the shadows will confuse things.
the pool lights are also part of the decor so some may like certain ones as they fit the theme better. I feel I do not want my living room to look like a drug store with harsh light. I'd prefer a more relaxed atmosphere. the color of light and intensity do affect a buyers decisions. They can also have an effect on moods. when you shop you will often notice bright halides used for this reason. a fast food restaurant may use this to try to get the customer not to stay long , because they want the table to turn over, a relaxed pizza parlor or a pool hall may want more relaxed lighting so that the customer will sit and have a couple of beer and maybe spend a little more. bars and restaraunts usually use subdued lighting in a restaraunt they may choose the lighting that makes food more appealing, the wrong light makes what is on the plate less appealing. haide may be one that restaraunts prefer, maybe it makes the broccoli look more appetizing for example.
