How to turn a 60 watt bulb into 300 watt!


Just accidentally knock over the lamp while it's turned on.

I accidentally did this while vacuuming and guess the filament must of jumped in a way and reconnected itself to make itself shorter, I have never seen a 60 watt bulb this bright! I'm not sure how long it's going to last though.

You have inadvertently made the bulb into one that is rated for a much lower voltage.

A (n old fashioned incandescent) photoflood lamp (bulb) is simply one rated for a lower voltage (that would give a 750 to 1000 hour lifetime) than the intended (120 volt) operating voltage. Its life is typically something like five hours. In the case of the photoflood, the intent is not only more light out of one lamp but also a more bluish cast (higher color temperature and also higher actual filament temperature).

RS: You remind me of a similar situation. I replaced the dome lamp in my car. There was no problem for a day or so until it no longer came on. Checked the bulb, it was OK. The lamp circuit fuse had blown, replaced it but the same happened again. Out of frustration, I checked the current draw of the bulb -- it was a full 5amps. The specified rating of the bulb is 0.5amps. Oddly though, the brightness of the irregular lamp was the same as a normal lamp. I had called Tung-Sol about it, but nothing came of it.

I find it hard to believe that the bulb that drew 5 amps did not give much more light than the one that drew 1/2 amp.

Putting a higher wattage (or current) bulb where a lower wattage bulb was meant to go will overheat (and also melt plastic parts of) automotive sockets and fixtures just as in household fixtures.

This bulb of mine is still going strong! Well it seems slightly less bright, or I've just gotten used to it. It's never on for long though but it does get turned off/on a lot, so I'm surprised it did not blow. I would not leave it unattended though.

Maybe I should sell it on ebay as a magic light bulb.

I'm surprised the filament didn't give out before you finished writing this post!!!!
