There is actually no energy efficient light bulbs in a way to interpret in physical determination. Energy efficient means less Watts required per hour compared to non energy efficient.

How many years would it take to recoup the entire cost of low energy light bulbs?
A few months. You'll have to do the calculations by yourself, for your case - both the cost of light bulbs and the cost of electricity may vary depending on the region. Assume that the low-energy light bulbs use about half, or one third, of the old-style incandescente light bulbs.
What would happen if everyone in England used energy saving light bulbs?
Then the people themselves would save money. The higher cost of the light-bulbs is more than compensated by the savings in energy. Also, you would do a favor to planet Earth.
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.
What are the benefits of using LED lamps?
Lamps using LED bulbs are more energy efficient than lamps that use traditional light bulbs. LED bulbs last over 25 times longer than regular light bulbs. Though they may cost more at the outset, the cost of usage of LED lamps is much less over time.
What is the cost of light bulbs in 1989?
cheap
Why does an LED light cost so much?
LED bulbs cost so much because of the amount of life that you get from the bulbs. These bulbs are designed to last for years.
How much does a flourscent light bulb cost?
Flourescent light bulbs are approximately double the price of a standard bulb. There is an advantage to them though, they last longer and are more energy efficient.
Most cost efficient lighting in the long run?
any light bulbs that use effienct energy usage.. dont buy the big old fashioned florecent light bulbs or huge lights.. there are many new items to use for lighting.
What are the effects of saving energy?
Saving energy helps reduce greenhouse gas emissions, combat climate change, and lower energy costs for individuals and businesses. It also promotes sustainable development and helps conserve natural resources for future generations.
What are the benefits of using fluorescent bulbs?
Fluorescent light bulbs have been shown to use one quarter less energy than a typical incandescent light bulb and they last longer. You will save money on utility bills (despite the initial cost) and will help save the environment by using bulbs which last longer.
Why is the energy of a flashlight heat and light energy?
because old - style light bulbs work by passing an electric current through a thin piece of metal (tungsten is commonly used in these) to heat it up enough to make it glow. In these old - fashioned light bulbs, most of the input energy is given out as heat (about 95%) and the rest light. However, in new, so called,"energy efficient" light bulbs, an electric current is passed through different gases (including mercury gas) to make the particles collide with each - other and give out light. Depending what metal vapour you use determines the colour of the light given off. These are more energy efficient because about 60% of the energy given out is heat, and 40% light, so it isn't ideal, but is better than the old light bulbs. However, these new light bulbs might not be entirely benefitial as they are less cost - effective than the old ones. Written by a 12 - year old!
What is meant by lost energy in relation to light bulbs?
It means that only part of the electrical energy used up gets converted into useful light; another part of the energy gets converted into other types of energy, mainly heat. If this energy waste could be avoided (so that the light bulb produces only light, and no heat), then you would get the same result at a lower cost.
