This is variation 2 of my solar powered function light-weight. I extra a modest 12v lithium battery pack (solar billed of program) and modified the LED driver to double the light-weight output and then mounted the lamp on a modest digital camera tripod.
I also evaluate the 12v lithium battery pack I very first protected in a mail bag video previous 7 days (features url):
This is the battery pack info I observed in my on-line analysis:

I’m receiving capacity readings in the 1800mAH assortment at .six amps discharge rate. I’ve re-examined it with .5 amps and may well consider with .four amps as that extra intently matches the LED load, and get very similar capacity readings.
This would make for a pleasant, moveable configuration. The battery pack ought to give about 5 hrs of operate time. The digital camera tripod has a tilt/pivot head to allow for for positioning the light-weight and it has telescoping legs to increase and lower the light-weight.
I’m pretty joyful with the way it turned out. It will light-weight up a dim space pretty properly and throws a really broad beam pattern. My digital camera would not clearly show the lighting have an affect on of the lamp really very well, so I did not shoot any video of the light-weight output. If there is desire in that, I may give it a consider with my new camcorder after I get it doing the job.
For upcoming advancements, I could set up a co-axial ability jack into the aspect of the driver housing to allow for the battery pack to plug specifically in and eradicate that extra duration of cable. I also have 600mA and 900mA frequent current LED motorists on order, so want to consider that in its place of the inefficient sequence resistor.
I believe I ought to be ready to make use of this light-weight for filming upcoming movies, I by now used it to movie aspect of my above the air Television set method video:

I’ve operate the light-weight on for numerous hrs with no troubles, the housing is just scarcely heat to the touch. Also been making use of if for lighting on a few movies and with the manual white balance on the new camcorder, it works wonderful.
I used a Hakuba mini-tripod, charge about $twenty from Frys Electronics, the 12v battery pack, about $23 on eBay, and the 12v 10W LED flood lamp that are all around $10 on eBay, just lookup for “10w led flood light-weight 12v” and you can expect to discover dozens of listings.
And someone will have to believe this is a good plan, since now they are selling rechargeable LED flood lights:
