To do something like that you would first have to have each light on it's own smart switch. Then you would need a master switch that would control each of the other smart switches. You can find switches like this at www.smarthome.com
there are 98 different kinds of light bulbs. including colored light bulbs
LED light bulbs definitely are more energy efficient than regularly normal light bulbs. Depending on the usage, LED lights can also last maybe twice or three times as much as regular bulbs. LED ones are better.
if its burnt out, replace it, if not, check the wireing
The maximum voltage of incandescent light bulbs is up to about three hundred volts. They can also go down as low as 1.5 volts. Incandescent light bulbs are the least efficient lighting system. More modern methods like flourescent lightbulbs are far more efficient.
Since the bulbs are in series, each one will have 40 volts across it instead of the 120 volts it was designed for. The bulbs will glow very dimly or not at all.
The three sources of white light are the sun, incandescent light bulbs, and fluorescent light bulbs.
Turn switch A on and then wait for a couple minutes. Turn switch A off and switch B on. Go to the attic, one light bulb should be on, that's switch B. Now feel the light bulbs, one should still be warm from having been turned on and then off, that's switch A. The one that's off and cool is switch C.
Three 20 watts bulbs will consume 60 watts.
How did you want to switch on the bulbs? If there isn't a separate circuit already running from the switch, through the wall, and to the chandelier, then you'd have buy pull chain switches. The chandelier would have to have holes drilled to mount the switches. The load wire from the house would be wired to the load side of each switch. Then two bulbs to one switch and three bulbs to the other switch. All the neutrals would tie together to the neutral from the house. I would HIGHLY recommend just purchasing a dimmer switch from your local hardware or home center. You could easily change the switch in the wall to a dimmer switch and have a lot more control over the illumination, and it wouldn't look like you have burned out light bulbs in your fixture. You can rewire a 5-bulb light for a 3-2 switch in a couple of other ways. Remove the light from the ceiling, open the lamp wiring and divide the selected 3 and 3-light sets. All of the neutral wires stay together (usually wired to the screw shell of the lamp holders). Add a 3-way switch in the fixture (e.g., off, 3-on, 5-on, or off, 2-on, 5-on) or bring each group of 3 and 2 hot wires out to separate wall switches. Switch 1 is 2 bulbs, switch 2 is the other 3 bulbs, and switch 1 and 2 together is all 5 bulbs. Or you can put all or some of them on dimmers.

A three-pole light switch has three separate switches that control one light fixture, allowing for more control over the lighting. In terms of wiring, a three-pole switch requires an additional wire compared to a standard switch to accommodate the extra switch.

Interesting.
Parallel.
The sun, fire, and light bulbs are three things that give off light and heat. The sun is a natural source of light and heat, fire is created through combustion, and light bulbs produce light and heat through electricity.
