What would be REALLY neat is is someone could fit the whole battery, resistor and switch into the metal part of the bulb. A "Flashlightbulb" if you will.

Yup...that's the next article :-) If you look closely, you can see the white LED on the testing board. We are looking for the right size button battery so it can fit into the bottom hole.
The switch will be at the bottom...pressing it for on/off

@ EJCrews - someone at Toshiba patented something like you describe a few years ago. It looked just like a regular lightbulb, and fitted into a standard fitting, but hidden in the metal bit was a battery and a tiny step-down voltage, rectifier and charger, that both charged the battery and lit up the low-voltage filament in the bulb. So it looked like a regular light bulb, and appeared to work like one. But if you unscrewed it from the fitting, and pressed a button hidden on the base, it would light up again and you could use it as a flashlight.
Don't know if it ever went into production, and I can't find the patent unfortunately.

We found some LED pens which fit perfectly ...we just have to shorten the barrel so the switch is just at the bottom of the bulb!

LED bulbs for household use have already been around for some time, but their success has been limited. The main obstacles have been that they cost more than incandescent lightbulbs.
Things are changed this year, LED bulb price droped by %50. http://www.1topstore.com is a leading LED supplier, they provide various LED lightbulbs. including gu10 led bulb, E27 led bulb, E14 led bulb, MR16 led bulb and Solar LED light.
Edison bulb will last for 750 to 3,000 hours, while an LED has to be replaced only every 50,000 hours (or 10 to 30 years). the cost savings is almost $740 over a lifetime due to much lower energy consumption. it is time to change from Edison bulb to led bulb. Not only for saving money but also save our earth.
