At present there are several types of light bulbs available for indoor domestic use.
Arranged by their efficiency from least-to-most they are:
Incandescent bulbs (60 watts)
The old style light bulb emitting light from a hot filament
Fluorescent tubes (30 to 40 watts)
Several inch to several foot long tubes emitting light from a vacuum with a trace of Mercury vapour requiring a special fixture
Compact Fluorescent bulbs (15 watts)
Roughly incandescent sized small fluorescent tubes designed to screw into standard light bulb fixtures
Light Emitting Diode /LED's (5 watts)
Small cool running lights using special mini-sockets or designed to fit into conventional sockets.
Notes:
- Power requirements to provide as much light as a 60 watt incandescent bulb indicated in parentheses
- Both types of fluorescent tubes contain Mercury and require special handling and disposal requirements
- Outdoor lights would also include Mercury and Sodium vapour bulbs as well as high powered incandescent bulbs. These are more efficient than incandescent bulbs but the colour spectrum emitted and other aspects makes indoor use unlikely

Does a light dimmer work with the new energy efficient light bulbs?
If you are looking to use the new energy efficient light bulbs on a light dimmer you will need to buy specially made dimmable CFLs. Not all energy efficient light bulbs are compatible with dimmers so be sure to check the packaging for information.
What advantages do LEDS have over light bulbs?
LEDs are definitely better than the ordinary light bulbs because they're more energy efficient, and you'll be able to get a lot of savings since you don't need to change your bulbs every now and then.
What is the maximum voltage of incandescent light bulbs?
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.
What is most energy efficient led lamps or bulbs?
The most efficient outdoor light bulb would the 5 watt Light emitting Diode light bulb also know as the LED bulb. They are small lights with miniature sockets or made to fit into conventional sockets.
Why do ordinary light bulbs take more electrical energy than efficient bulbs?
The filament on normal light bulbs require a higher current of electricity to light up, and are more resistant to electricity as well. This causes it to use more electricity and generate more heat.
Is compact fluorescent light the best energy saving bulb?
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
What are some of the most energy efficient light bulbs?
Some of the most well known and highly rated energy efficient light bulbs are made by NanoLight, EcoSmart, Philips, and Chevron. These can be found at any local Home Depot.
Which Lighting will be the most energy efficient?
Compact fluorescent light bulbs are pretty energy efficient and are energy star rated.
What is the most energy efficient light bulb?
Light bulbs in order of the least to most energy efficient : incandescent, halogen, fluorescent, LED. For home owners, most reasonable is the CFL lightbulb, which is cheaper and longer lasting than the LED.
Are light bulbs really efficient?
Normal incandescent bulbs produce a lot of heat as well as light, so are not so efficient as low energy bulbs which can give the same light but consume much less electricity
Does a light dimmer work with the new energy efficient light bulbs?
If you are looking to use the new energy efficient light bulbs on a light dimmer you will need to buy specially made dimmable CFLs. Not all energy efficient light bulbs are compatible with dimmers so be sure to check the packaging for information.
Where can one purchase energy efficient incandescent light bulbs?
Energy efficient incandescent light bulbs can be purchased from most lighting stores and major supermarkets. They can also be purchased online at places like Home Depot, Amazon and Earth Easy.
Which light bulbs are the most efficient and last the longest?
Fluorescant light bulbs are much more efficient than incandescant, (lasting up to 7 years) and provide more light as well. They can save you hundreds of dollars on energy per year, depending on the number you replace.
How efficient is a light bulb?
Incandescent light bulbs are the least efficient, converting only about 10% of the electricity they use into light. LED light bulbs are much more efficient, converting around 90% of electricity into light. CFL bulbs fall in between, with an efficiency of about 60-70%.
What makes LED light fixtures energy efficient?
LED light fixtures are made out of clusters of very small, super energy efficient bulbs. Because many of those bulbs are used, LED lights can be built to mimic the effects of regular incandescent bulbs. A huge part of what makes LED bulbs so energy efficient is that they do not produce heat as incandescent light bulbs do.
What advantages do LEDS have over light bulbs?
LEDs are definitely better than the ordinary light bulbs because they're more energy efficient, and you'll be able to get a lot of savings since you don't need to change your bulbs every now and then.
How efficient are commercial light bulbs compared to industrial light bulbs?
Industrial light bulbs typically have larger wattage than commercial light bulbs. This is because commercial light bulbs are more commonly used in public as opposed to private homes.
