How much energy does an incandescent lightbulb use versus a fluorescent?
Yes that's true fluorescent bulbs are better because it usess 75% less energy and works longer than a incandescent light bulb. Yes...and no. It is true that power usage decreases with fluorescent balb usage. However, one must take into account that they pollute more (i.e. mercury and other heavy metals).
Can you put compact fluorescent bulbs in range hoods?
Only if they are enclosed behind a glass shield or window.
Why is the plimsoll line so important in terms of density?
The plimsoll line shows how GAY boats are, and how scared the captain is of putting "too much freight" on the boatHere is a random bit of text:An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light which produces light with a filamentwire heated to a high temperature by an electric current passing through it, until it glows (see Incandescence). The hot filament is protected from oxidation with a glass bulb that is filled with inert gas (or evacuated). In a halogen lamp, filament evaporation is prevented by a chemical process that redeposits metal vapor onto the filament, extending its life. The light bulb is supplied with electrical current by feed-through terminals or wires embedded in the glass. Most bulbs are used in a socket which provides mechanical support and electrical connections.Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external regulating equipment, have low manufacturing costs, and work equally well on either alternating current or direct current. As a result, the incandescent lamp is widely used in household and commercial lighting, for portable lighting such as table lamps, car headlamps, and flashlights, and for decorative and advertising lighting.Incandescent bulbs are much less efficient than most other types of lighting; most incandescent bulbs convert less than 5% of the energy they use into visible light[1](with the remaining energy being converted into heat). The luminous efficacy of a typical incandescent bulb is 16 lumens per watt, compared to the 60 lm/W of a compact fluorescent bulb. Some applications of the incandescent bulb deliberately use the heat generated by the filament. Such applications include incubators, brooding boxes for poultry, heat lights for reptile tanks,[2][3]infrared heating for industrial heating and drying processes, lava lamps, and the Easy-Bake Oven toy. Incandescent bulbs also have short lifetimes compared with other types of lighting; around 1000 hours for home light bulbs versus up to 10,000 hours for compact fluorescents and up to 100,000 hours for LED lamps.Because of their inefficiency, incandescent light bulbs are gradually being replaced in many applications by other types of electric lights, such as fluorescent lamps, compact fluorescent lamps (CFL), cold cathode fluorescent lamps (CCFL), high-intensity discharge lamps, and light-emitting diode lamps (LED). Some jurisdictions, such as the European Union, are in the process of phasing out the use of incandescent light bulbs.sincerely, Einstein
Do LED lights get hot?
While they don't get as hot as incandescent bulbs, LED lights still do generate a bit of heat. Proper cooling is required, usually in the form of a headsync to maintain the life of the lights.
What is the lumen output for a 35W halogen?
It varies from about 600 to 1100 lumens. Typically the higher the lumens output, the shorter the lifespan of the globe. Have a look at this list of globes for purchase whih shows wattage and lumens: http://1000bulbs.com/category/75-watt-incandescent-standard-shape-light-bulbs/
