Fluorescent lights help the environment by conserving energy and being more efficient.Traditional bulbs produce about 15 lumens per watt, while fluorescent bulbs produce between 50 to 100 lumens per watt. This makes fluorescents bulbs five or six times more efficient than traditional bulbs.Also, the concepts behind the two bulbs are different. Traditional, or incandescent bulbs create heat in order to create light, which wastes a lot of energy. Fluorescent bulbs use a gas containing argon and mercury vapor that creates ultraviolet photons.This helps the environment by not wasting resources.Alternative AnswerFluorescent lamps might lower your electricity bill, but they use more energy and resources to manufacture, compared with incandescent lamps. They also contain mercury and other toxins. So fluorescent lamps probably do more damage to the environment than incandescent lamps. So, if you want to save on your energy bills, use fluorescent lamps; if you want to protect the environment, then use incandescent lamps.
That depends a LOT on the technology used - some technologies are much more efficient than other (converting a higher percentage of the power used into visible light).

Since LED bulbs come in a variety of sizes there is no one answer. If we consider Watts then LED bulbs from 1 to 12 Watts are common. The higher end of quality LED lights that are commercially produced generally yield about 80 lumens per Watt. This means for a 10 Watt LED bulb your looking at 800 Lumens. This is higher than both CFL and incandescent lights. LED bulbs can save money in the long run due to the lower energy use, but they require a larger up front investment. See below for a link to an example of an LED bulb that produces 460 lumens.
A 26-watt compact fluorescent lamp typically produces around 1,700 lumens.
A 32 watt fluorescent bulb typically produces around 2400-2900 lumens of light output. The exact lumen output can vary depending on the specific type and brand of the fluorescent bulb.
It's about 600 lumens. The same brightness comes from a 12 Watt compact fluorescent light (CFL).
10-11 lumens per watt for incandescent bulbs 13-14 lumens per watt for halogen 50-60 lumens per watt for fluorescent
9000- 11000
The main types are: Incandescent 10 lumens per watt Halogen 13 lumens per watt Fluorescent 40-50 lumens per watt LED 40-60 lumens per watt Lumens measures the brightness, watts measures the electric power used.
Currently maximum LED luminous efficiency is about 114 lumens/W, measured at 50mA. Average luminous efficiency is about 104 lumens/W. Ordinary LED light effect is about 60 lumens / W. 18W is about 130 lumens is about 1080 lumens.
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.
The most energy-efficient option among the ones listed is the compact fluorescent light bulb (CFL). It uses about 75% less energy than incandescent bulbs, lasts longer, and produces less heat. Halogen bulbs are more efficient than incandescent ones but are less so compared to CFLs.
The answer is 40 watts, power is a rate of energy. If you are looking for the total amount of energy it uses over its life, take its expected life and multiply it by 40 watts, which will give you your watt-hours. For example Expected life of the bulb is 2000 hrs Then it would be 2000*40 = 80,000 watt - hours or 80 KW-Hours Power companys charge by the KW hour used
Compact fluorescent bulbs are widely used because they use one fifth of the electric power to provide the same amount of light as an incandescent bulb. Incandescent: 12 lumens per watt Halogen: 15 lumens per watt CFL: 50-60 lumens per watt LED: 100 lumens per watt High-pressure sodium: 200 lumens per watt
Approximately 15 lumens per watt for halogen, so 300 lumens.
