lighting color is typically a preference. In a room like the garage, laundry or storage room, you may want more light and whiter is better. but i rooms like the library kitchen or bedrooms incandescent colors or are more soft and soothing also we use them to see clearly at light like the lights the lights that we use outside for parties and stuff.

What does an led do in an electronic circuit?
the function of an led is to give of light coming through an electrical circuit
How do you wire a ceiling light from five different locations?
=== === In the ceiling box there may be a Black wire, a Red wire, a White wire and a Green or Bare wire. The light fixture may only have a Black wire, a White wire and it may or may not have a Green or a Bare wire.The Black wire in the ceiling box may or may not be be a "Hot traveler" wire coming from the lighting circuit breaker on the main panel. The Red wire may or may not be a "Switched Hot" coming from the light switch for this light. The White wire should be a Neutral coming from the main panel. The Green wire should only ever be a safety Ground wire coming from the main panel.Or there may be a two-way switched circuit feeding the light. If it is a light near some stairs and you have 2 switches controlling it, one switch downstairs and another switch upstairs, then the wiring could well be as follows: the Red (or the Black) is a "hot feed" to the switches and the other one, the Black (or the Red) is the "hot return" from the switches. (There would also have to be a further wire, a "Hot Common" wire running between the switches which could be any color other than Green or Bare and it may or may not appear in the ceiling box, it depends where the switches are located.)The light fixture must be hooked-up as follows:If the light fixture has a Green or Bare wire it must be connected to the Green or Bare wire in the ceiling box. (On European fittings the Ground or Earth wire is Yellow/Green.) If the Neutral on the light fixture is a White wire it must be connected to the White wire in the ceiling box. (On European fittings the Neutral is a Blue wire.) If the Hot on the light fixture is a Black wire it must be connected to the switched hot wire in the ceiling box, which may be Red or it may be Black: you must check which wire is the correct one to use or the light will not be switched off by the switch! (On European fittings the Hot or Live is a Brown wire.)For more information see the answer to the Related Question shown below. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work ANDalways use an electrician's test meter having metal-tipped probes(not a simple proximity voltage indicator)to insure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How many 150 watt flood lights can be on a 20 amp circuit?
The voltage needs to be known to give an answer to this question.
How do you split light?
Yes. (White) light can be split into the 7 colour spectrum; red, orange, yellow, green, blue, indigo and violet. White light can be split into the colour spectrum by passing it through a triangular prism, as Sir Isaac Newton did sometime between 1670 and 1672. This is a process known as dispersion.http://www.school-for-champions.com/science/images/light_dispersion1.gifIn the above picture, you can see the white light entering the prism from the left and dispersing into the 7 colour spectrum on the right. The colours at the top of the rainbow bend less than the ones at the bottom. A second prism the same way up placed next to the first prism, will give a greater dispersion of the spectrum. A second prism the other way up placed next to the first prism, will recombine the spectrum to form white light, thus reversing the process.This same process occurs in raindrops and this is why you see a rainbow in the sky when it rains.Read more: Can_you_split_white_light_into_the_color_spectrum
If the wiring in your ceiling box is black white red and green but the light fixture only has black white and bare what do you do with the red ceiling wire?
Answer for USA, Canada and countries running a 60 Hz power supply service.Learn how to use a voltmeter, or at least a neon test lamp, and check those wires out before you touch any of them!That said, the bare wire on your fixture should connect to the green ground wire in your electrical box. The white neutral wire should go to the white, and your black (hot) wire for your fixture probably goes to the black wire in the box - you will need a voltmeter to take readings of the potential between the neutral and the black, then the neutral and the red, and see if the black or red is controlled by the the switch.The Black wire may be a "hot traveler" wire coming from the lighting circuit breaker on the main panel. The Red wire may be "switched hot" coming from the light switch for this light fitting. The white wire may be a Neutral coming from the main panel. The Green wire should only ever be a safety Ground wire coming from the main panel.Or there may be a two-way switched circuit feeding that light. If it is a light near some stairs and you have 2 switches controlling it, one switch downstairs and another switch upstairs, then the wiring could well be as follows: the Red (or the Black) is a "hot feed" to the switches and the other one, the Black (or the Red) is the "hot return" from the switches.However you must not just assume any of these suggestions about wiring colors is correct for your house.If you don't know how to check these things safelyDON'T DO IT - YOU COULD KILL YOURSELF!As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
