Yes, non energy efficient bulbs like the incandescents waste around 90% of there energy in the form of heat. LEDs and CFLs don't even come close.

Lose less energy as heat.
Yes. Part of the energy is converted to light, part to heat. The percentage depends on the type of light bulb. Fluorescent and LED light bulbs are more efficient than incandescent light bulbs. A 60-watt incandescent bulb will be uncomfortable to remove from the socket with your bare hands after turning it off. However, a 100-watt bulb will burn you if you remove it with your bare hands after turning it off.
Yes. They're cool compared to incandescent bulbs of the same light output, but they do produce some heat.
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
If you are comparing parallel vs series circuits, light bulbs produce more light in parallel circuits.
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.
Yes, non energy efficient bulbs like the incandescents waste around 90% of there energy in the form of heat. LEDs and CFLs don't even come close.
comparing to the traditional light bulbs energy efficient fluorescent light bulbs uses 25% to 75% energy and saves money also and it lasts up to 3 to 25 times long so there is no need to replace energy efficient fluorescent light bulbs often.
No. Light bulbs produce non-polarized light.
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.
Yes, but its more of the result of the reaction, which is heat and light. More efficient is florescent which produce more light than heat.
No light bulbs actually save energy, they use it to produce light. However energy efficient bulbs use less energy than the ordinary incandescent type. To my mind describing them as energy saving is wrong, they should be described as "lower energy" bulbs.
Conventional incandescent bulbs are extremely inefficient because they use a piece of wire heated to white heat to produce the light. That means that they also produce a lot of heat, which is wasted energy. CFL bulbs produce light more directly and they produce about one fifth of the amount of heat energy.
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.
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.
