Any electrical device "raises your electric bill", but only when it is activated. (only when you turn on the switch)
A 100 watt bulb, left on for 10 hours uses 1 KW-hr.
A 10 watt bulb left on for 100 hours uses 1 KW-hr.
It becomes relatively simple to understand that if the power company charges you a set price (for example $0.15/KW-Hr) the 10 watt bulb would raise your electric bill much more slowly than would the 100 watt bulb.
Saving energy means you use less energy from the company that supplies your electricity. Hence your bill will be less. You are charged in Watt Hours. If you turn on an incandescent 100 Watt bulb for an hour the electric company will charge you about 12 cents. If you use an LED bulb which gives the same light and only consumes 20 Watts, it only costs about 2.4 cents per hour.
Approximately 5 kilowatt hours. Check your electric bill to see what you are charged per kilowatt hour.
No. A 70 Watt metal halide bulb can not be replaced with a 150 Watt halide bulb.
Incandescent bulbs give about 10 lumens of light per watt of electric power Halogens give about 13 lumens per watt CFLs give about 50 lumens per watt So it depends on the type of bulb.
Yes, the halogen bulb would provide about 30% more brightness (lumens) for the same electric power rating. So 70 watt halogen is about equal to 90-100 watt incandescent.

A 0 Watt bulb does not consume electric power so the cost is zero.
Approximately 5 kilowatt hours. Check your electric bill to see what you are charged per kilowatt hour.
No. A 70 Watt metal halide bulb can not be replaced with a 150 Watt halide bulb.
NO. The amount of electric energy consumed varies depending on how high or low the setting is. Low setting will use less electric than high setting just as a 100 watt bulb uses less electric than a 200 watt bulb.

Watt is a unit of power. watt hours is a unit of energy. (Note x watts times y hours is what you pay for on your electric bill.)
Yes.
A watt is a measurement of electricity, usually pertaining to light. Light bulbs luminosity is graded by wattage, such as a 60 watt bulb, 100 watt bulb and so on. You would find a watt in a light bulb, to start.
The electric power measured in watts is used to heat a filament in the light bulb (which glows because it is very hot). More energy gives more heat. It's very simple.
If it is an 18 watt 12 volt bulb, then yes. But an 18 watt 120 volt bulb - then no.
