      Thomas Edison obtained an exclusive license to the Canadian patent. Thomas Edison developed his own design of incandescent lamp with a high resistance thin filament of carbon in a high vacuum contained in a tightly sealed glass bulb which had a sufficiently long service life to be commercially practical.

      Historians Robert Friedel and Paul Israel list 22 inventors of incandescent lamps prior to Joseph Swan and Thomas Edison. They conclude that Edison's version was able to outstrip the others because of a combination of three factors: an effective incandescent material, a higher vacuum than others were able to achieve and a high resistance that made power distribution from a centralized source economically viable.

      Another historian, Thomas Hughes, has attributed Edison's success to the fact that he developed an entire, integrated system of electric lighting.

      The lamp was a small component in his system of electric lighting, and no more critical to its effective functioning than the Edison Jumbo generator, the Edison main and feeder, and the parallel-distribution system. Other inventors with generators and incandescent lamps, and with comparable ingenuity and excellence, have long been forgotten because their creators did not preside over their introduction in a system of lighting.

Sir William Armstrong can only keep thirty-seven lamps going ; Lane- Fox could only show twelve lights ; Professor Adams could only produce from the most powerful dynamo-electric machine, by calculation, one hundred and forty lamps. Where is the subdivision ?

      Popular Science Monthly/Volume 19/July 1881/Recent Advances in Electric Lighting

    Edison would have loved LEDs and hated CFLs. LEDs are always DC and CFL always AC inside.

    My shop is lit with a row of fluorescent tubes and a bunch of very large (200 watt) incandescent bulbs. Winters are brutal on the fluorescent bulbs. They flicker a lot while the ballast warms up. As well we replace more fluorescent tubes each year in the shop than bulbs (why would cold affect the tubes?). Which is nice because the bulbs are 20 feet overhead. Getting reliable, energy-efficient replacements for these bulbs would be very nice but I haven't seen any yet.

    The problem with fluorescent tubes is that they need a sufficient temperature to get the correct mercury vapor pressure in the tube. If the pressure is too low, the discharge current will be too low giving poor light out, and an unstable discharge leading to flickering. The tube will need an abnormally high a voltage from the ballast, this will cause excessive sputtering from the tube filaments, shortening the tube life dramatically.

    To an extent, the use of electronic ballasts can help, as electronic ballasts operate in an almost constant-power mode, whereas magnetic ballasts act instead as a current limiter. If the tube pressure is too low, the electronic ballast will still deliver near full power to the tube, whereas the magnetic ballast will severely underdrive the tube, leading to a prolonged warm-up time, during which time the tube is overstressed. Electronic ballasts also prolong the life of the tube and improve efficiency and reduce flicker due to the use of high frequency drive.

    For extremely cold environements, you need to use low temperature fluorescent tubes. These use a different gas mix and mercury charge, this ensures that the discharge is stable and tube parameters appropriate at temperatures as low as -40 C.

    He'd be shocking animals to death with the new lightbulbs, suing Westinghouse and Tesla and everyone else, and in general acting like any other a$$hole - because that's what he was, and that's what he did, as well as cheating Tesla out of $$$ - all putting the "Con" in "Con Edison."

    Uhhh...how EXACTLY is that flamebait? doesn't anyone know their history anymore? it was Edison that was frying animals and pushing for the electric chair because he was sure it would discredit Tesla and AC power and since he had DC patented up the ass he stood to make a fortune if he pulled it off. its pretty common knowledge that even after it was proven that with the tech of the time DC just wouldn't scale Edison was pushing for "neighborhood generators' belching out coal smoke to power a couple of blocks rather than admit while DC had its uses it wasn't gonna work long distance.

    Sorry to burst anyone's bubbles but while Edison was a brilliant man he was also as ruthless as they come and had NO problem with deep roasting animals and people just to try to ruin a competitor. Hell Gates and Jobs didn't have nothing on Edison as i can't really picture Jobs having someone bashed to death with an IBM PC to "prove" they were unsafe.

    No, because it is impossible to prove. I call it the post-mortem fallacy: where someone argues a position is held by another who was dead long before he or she could have had any opinion on the topic. We don't know what opinion Edison would have had on the new law.

    Tesla was amazing. Edison was a huge jerk-hole. There's a lot of detail that has already been said supporting my position. I just wish the rest of the world would learn about the two and how we have Tesla to thank for AC power and a lot more.

    The problem is that Tesla's story also includes his vision for FREE ENERGY. If you can't put a meter on it, you can't add it to the history books... or something like that.
