Yes, I know about those and have already agreed with you that they're real, but they're totally different to the one in the photograph posted by the original poster, which is fake.

Can you really not tell the difference?

The photograph in the original post, which is fake.

Hey, the OP has already solved this riddle (reply #7). There is indeed a small battery in the base of that lightbulb, it is not a fake image.

It's not a commercially available bulb, and the operating time will not make it too practical in daily use or as emergency lighting. But I can totally see its potential in practical jokes!  ;)

EDIT: Changed the reply # which I referred to, since Peter Erskine has chosen to delete a few posts of his.
(I recommend against that, Peter. It breaks the flow of the dialog in the thread, and your posts are documented in the quotes anyway. Better to edit your post, strike out what you no longer uphold, and add a comment explaining why.)

Sorry I didn't click on the link. Yes, real after all, but not practical like the commercial products, which are totally different.

It's wireless, and has no ground reference. I don't know how to define it's potential.

Oops, looks like I should have spotted the potential difference of opinions over how it worked, didn't mean to start a flame war  :). I figured it is so easy to fake photos these days, that doing so would be considered cheating...

Nusa:
It may be over for you, but April 1st isn't yet over worldwide. Give it a few more hours before anything is back to normal levels of believability.

Cyberdragon:
You could also do it induction powered with a coil in the base. Tesla invented them as part of his whole wireless power scheme. In fact you can buy floating induction lamps as a novelty item.

Also, a battery and bulb (not sure if integrated) was probably used in the "cheese lamp" prank on the Carbanaro Effect.



You could do this with any normal lamp using those emergency backup bulbs as any conductive substance like fruit or something would trigger it.
