Joule Thief (3 Light test) 019

Joule Thief Test to check the differences between a 3v incandescent bulb an Led and a Joule Thief Based LED..

The incandescent bulb sucked.

The LED just on Normal worked OK and would easily out shine the incandescent bulb.

But the Joule thief circuit Was Brighter and I am guessing will last much longer.

They all had fresh batteries put in them at the start of the test and I might just leave them running to see for myself which is best. I will post the results if I do.

Enjoy...

Paul.

I've done lots of those joule thief to many i guess but still i like the way they work and how simple they are. Not sure if you know it but the bigger you "power" wire is the more amp you will get back of course will increase the input slightly less turn you make higher frequency and higher amp too and vice versa. Also found some nice simple schematic on the net that add small .01uF cap to add more power.

Thanks for the info, I will consider this next time I design one....

Every piece of electrical equipment in the world could someday have a sticker on the out side that says:

"Joule Thief Green Circuitry Inside"

Awesome video! 8)

;-) Thanks, and why not, It works with other stuff like motors and fans, Can you imagine how efficient a laptop would be with a Joule thief screen?

Just get the battery charged off the other side and then back again....

i agree there are many useful applications of the Joule Thief. I can light LEDS, Fluoros, CFLS and charge batteries for much less energy than conventional circuits.

great work once again Paul

whats this joule theif thingy? im intrigued

[sonichedgie]

the warmth of the Incandescent Bulb is what LED cannot copy .

Incandescent Bulb can light up wider range too .

What many dont know,,and this is not a bash on the economy or anything. But things are made intentionally to consume or use a certain amount of energy. This is to keep the household power uses set so to speak to a minimum of usage. Thats economy for you. So many things could be made to use way less power if they were made differently, but thats life I guess. Just thought I would put that out there for those that did not know!
