Which by the way is why it was government subsidized over more efficient LED light bubs that posses no Mercury. Everyone finds the dumbest conspiracies and ignores the real ones.
The excess heat from too large a bulb will shorten the life of the bulb in an enclosed fixture. Also, there is always the danger of too large a bulb causing overheating in the wiring and a possible fire. Never use a bulb larger than the fixture was designed to handle. If you want more light why not use compact fluorescent lamp? CFLs take about one fifth of the power that a normal incandescent lamp takes and give the same light output. So with a 15 watt CFL you could have the extra brightness you want (as if from a normal 75 watt bulb), the light fixture would not be at risk of overheating - and if you use the lamp for more than about an hour a day you should even save money on your electricity bills! You could even use a 20 watt CFL (giving the same output as a 100 watt normal bulb) and it will not overheat the light fixture. The only downside is that you can choose from various different shapes of CFL. Some CFLs may not look ok in your existing light fixture - it's a matter of personal preference - some CFL's can "look weird" in some fixtures! If you still want to use a CFL, to get the brighter light and saving of electricity costs, you may wish to change the fixture itself so that the new CFL will look ok. Always be sure to switch off the breakers at the main panel before you attempt to do any work on any mains lighting or power circuit.
Incandescent Electric Light Bulb
Any answer to this question is going to be a matter of OPINION. In my opinion, his greatest Contribution to the modern world was the "Perfection" of the Incandescent Light Bulb. He did not invent the light bulb, but bought the Patent and made it a practical invention by finding a long lasting Filament and Atmosphere inside the bulb.The light bulb was a huge advancement to Civilization.
Patents do not disclose the race of the inventors. Asking such a thing would make a person subject to suspicions of being a racist.
In 1878, Joseph Swan, who had been experimenting with carbon filaments, reported he had successfully created a light bulb. In 1879 he demonstrated a working lamp during a lecture in Newcastle.Joseph Swan invented the light bulb because he wanted people to see in the dark cheap and efficiently. He invent ed the light bulb in 1860, and received a patent for it in 1879.~Tony
When you compare a CFL (Compact Fluorescent Lamp) bulb to an LED bulb, the CFL bulb has a shorter lifespan. The CFL bulb also uses more electricity for the same brightness Also a CFL lasts longer and uses less electricity (for the same brightness) than an incandescent bulb.
A 240 v 14 w cfl bulb uses about 0.14 amps.
Over all, CFL light bulbs are good for the environment and they can save $. 1 CFL light bulb has 10 times the life span of a regular light bulb. 1 CFL light bulb could save enough energy to take a car from NY to San Francisco. 1 CFL light bulb uses between 50% and 80% less energy than a regular light bulb.

A 13 watt CFL bulb is roughly equivalent to an 8 watt LED bulb in terms of light output. Look for an LED bulb with around 8-9 watts and a lumens (brightness) output of approximately 800-900 lm to match the brightness of a 13 watt CFL bulb.
This is a bit less light than a 40W incandescent bulb (much less than a 9-watt CFL bulb, but twice as much as a 5-watt CFL mini-bulb).
I don't know. But the way to find out is www.USPTO.gov. The US Patent and Trademark Office. They allow searches by many criteria. It will take just a little work, but once you know how to search on USPTO, your power will increase.
Edward Hammer in 1976.
They are called CFL light bulbs. CFL stands for Compact Fluorescent Light .

All track lighting models can use CFL bulbs. The important thing is that you get the correct CFL bulb as you must get the CFL bulbs that are designed for base up use like you find in track lights, pendant lights and recessed lighting. If the track lights are dimmable you also want to be sure to get a dimmable CFL bulb.
Yes, it can. CFL's are good- they don't burn as much and they're good for the environment.
