Depending what your measuring for, they are usually measured in watts just as any other light. However, you can measure them in candles and temperature as well.

Which light bulb is best for cost saving?
Florescent light bulbs produce a similar amount of light with much less power than incandescent light bulbs. Their initial cost is paid back in energy savings. They also last a lot longer. I exchanged every light in my house for florescent bulbs years ago and I haven't changed more than 4 or 5 in all that time. LED bulbs are now on the market and are very expensive. But they use even less power to produce similar light and last many times longer than florescent bulbs. They are quite expensive, but what you get is an almost permanent bulb. In the future we will tell our grandchildren how we used to change light bulbs and they won't understand. I see a day when the bulbs become permanent parts of light fixtures and will not be replaceable in any typical sense.
Energy savings light bulbs flickering and do not dim on dimmer switch?
you can not put a normal dimmer on a florescent light. You need to install a dimmer made for flourecent lights and they are expensive about 50 dollar around here. If you want to dim it put a normal incandescent bulb in the fixture.
What is The electrical power used by light bulbs measured in?
Electrical power is measured in watts (W), just like any other type of power.Power is the rate at which energy is used. Energy is measured in joules (J), though utility bills usually measure energy using kilowatt-hours (kW·h) instead. 1 kW·h = 3,600,000 J.
How are light bulbs measured?
Brightness of a light bulb depends on the power, current, resistance and size of the filament. Lumens is the unit of measurement for the brightness of a bulb. A bulb has more brightness if there is more power and current. Greater the resistance, less is the brightness.
Are mercury vapor light bulbs which cycle on and off through out the night energy efficient vs fluorescent flood lights mounted on a motion detecting fixture?
First, if your Mercury vapor lights are cycling on and off you probably have a bad ballast. Any ballasted bulb will be much less efficient when cycling on and off. The greatest amount of power is used when the power is first transmitted through the gas within the bulb. Second, Florescent bulbs are just about as efficient as mercury vapor lumen for lumen. Hope this helps Terry
Do burnt out florescent bulbs use more energy than working florescent bulbs?
no
How does a florescent bulb work?
Florescent Bulbs are full of gases that create light when electricity is put threw them.
What is the scientific term for florescent light bulbs?
blackbody radiation
Do florescent light bulbs use less electricity?
yes
What is the difference between white fluorescent lights and yellow ones?
Florescent bulbs are environmental-friendly. Yellow bulbs use more electricity, but their lighting is generally better. Most florescent bulbs take at least a full minute to reach their full lighting, therefore conserving energy when you don't need full lighting. Florescent bulbs are environmental-friendly.

How is krypton used by man?
It is used to fill incandescent lightbulbs, florescent lightbulbs, and bulbs used for photography (flash bulbs)
Why gases are used in bulbs?
In incandescent bulbs, gases (other than oxygen) prolong the life of the filament. In florescent bulbs, the gas takes the place of the filament.
The power pf light bulbs in Measured in?
The power of light bulbs is measured in
What shouldn't dimmers be used for?
Dimmers do not work well with florescent lights. The should only be used with incandescent bulbs.
Why is krypton used in light bulbs?
Krypton is used with Argon as a low pressure filling gas for florescent lighting.
What is the green efficient squiggly light bulb called?
Florescent light-bulbs CFL Compact Fluorescent Lamp
Are compact fluorescent bulbs as eco friendly as people say they are?
I do not think so. The industries needed to manufacture compact florescent bulbs are much more complex and require many more natural resources than the old incandescent bulbs.
