Approximate luminous flux: 172.180 lumens

As a point of reference, a standard 100W light bulb typically is rated at around 1,700 lumens in North America, and around 1,300 lumens in 220V areas of the world.

Thanks for this information.  I always wondered how they would compare.  So, here in the US we would need about 10 of them to be around the same light as a 100 watt bulb.  That's not too bad really...a bit better than I thought.

Thanks,

Bill

@ All:

Since a good many of us have been or are working with LEDs, here is a great Makezene video explaining a lot about them including how to make your own:

I have some silicon carbide and I want to give this a try.

Hi there,  sorry for such a newbie question.
Can a joule thief charge a 12v battery, with 12v being the most practicable industry standard ( or multiples thereof) for power useage, then any reliable low voltage supply (earth battery, aerial collector) could be used to build up power?
Does anyone know if this is possible?

I just have uploaded my last video where i light on a 4 watt neon. It's a very very simple joule thief, no caps. The toroide makes a lot of noise, we don't hear it well on youtube except at 0:57min.
