whichever until its unplugged lol!!
compact floresent
He helped the Edison's make the light bulb last longer..
Edison failed many times - no one knows how many - to make a filament for a light bulb that would last a long time. He did not invent the light bulb - he was working on a BETTER light bulb that would last longer.
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.
i shouldn't think so.... it would be MAGIC.
because light bulbs use electricity ,and candles use fire, and electricity last longer
Actually it may last longer !!! This is due to the fact that less heat is made with one bulb.
We now have better materials for the filament and for the gas in the bulb, making them shine brighter and last longer.
A 13.5 volt bulb will burn less brightly but last longer.
If you want your bulbs to last longer then use 130 volt bulb on a 120 volt system. The light emitted by a 130 volt bulb, when comparing it to a 120 volt bulb, will be a bit dimmer.
he invented, (note: he didn't invent the light bulb he just improved it by making it last longer
A regular incandescent bulb uses a lot more energy than a compact fluorescent to produce the same amount of light. Most energy used by an incandescent bulb is wasted as heat which does not give off visible light. Incandescent bulbs are cheaper to buy, but they have shorter lifetimes than other alternatives.
