Usually the 60-watt limit is used to prevent the lampshade overheating, so a 75-watt bulb should not be used.
But if more brightness is required, try a low-energy bulb because a 15-watt one gives the same light as a 75-watt incandescent (old-style) bulb. Or a 20-watt would be even brighter.
You can, if you want to burn up your lamp. The socket rating is what is being stated, not the light bulb.
Yes, they have the same base, but use a lot less power then a 75w regular bulb.
Most 25w,- 100w bulbs and cfl have the same base.
If the socket threads of the lamp are the same then yes the bulbs can be interchanged. The 5 watt bulb will glow brighter than the 4 watt bulb. If by a 4 watt light you mean a 4 watt fixture, then it is not recommended to place a larger wattage lamp in a fixture that is rated by the manufacturer at a specific operating wattage
no the fixture has to be rated for the size and type of the bulb. most fixtures are not rated for 250W
Obviously not. It would blow the bulb by 600W! <<>> Yes you can use a 60 watt light bulb in a lampholder that is rated a 660 watts. The rating given to these lamp holders is the maximum amount of wattage that can be applied to them safely.
Providing the lamp is operating at its rated voltage, a 60-W lamp will require 60 W. Thought that should be self-evident!
Question is not clear; however, if you were to install a 120watt bulb into 90 watt rated socket then it may work for a while for some. yet, even if it works then after a while will start burning quite often and the fixtures itself will be damaged permanently

Provided the bulb is rated at 60 Watts or less and the fitting is compatible, yes.

Bulb brightness in LumensA 100 watt Bulb is rated at approximately 1700 lumensA 60 watt incandescent bulb is rated at approximately 800 lumensA 40 watt bulb is rated at approximately 400 lumensA 25 watt bulb is rated at approximately 180 lumensA 4 watt night light bulb is rated at approximately 20 lumens
The light bulb needs to match the ballast in the fixture.
The voltage isn't decided by the lamp, but by the supply the lamp is hooked up to.
The unit watt is defined as energy per unit time. Thus a 100W light bulb consumes 100J of energy each second. Joules are a unit of energy. Watts are a unit of power.
Yes, a 103 volt source will light a 60 watt light bulb. The relationship of the bulb's wattage output at a lower voltage, as to the normal voltage that the bulb is rated to operate on, the light output will be lower.
