Not necessarily. They can be brighter, or less bright. Both the energy saving light bulbs and the old-fasioned incandescent light bulbs come in different powers.
The difference between the two bulbs is that energy saving bulbs have murcuary in them which lowers the amount of electricity they require and consume.
Incandescent light bulbs waste a lot of energy by producing heat along with light, whereas energy-saving bulbs, such as LEDs or CFLs, are more efficient at converting electricity into light. Therefore, incandescent bulbs require more electrical energy to produce the same amount of light as energy-saving bulbs.
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.
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
EcoSmart, ArmorLite, Philips, GE, and Sylvania all make a line of energy saving light bulbs. They all manufacture LEDs, CFLs, and halogen bulbs. All of these bulbs are comparable in performance and all of these products are energy savers.
