Description
Electronics on the cheap - electricity for free.
I buy cheap electronics modules and components direct from Chinese sellers via eBay.
Most of this stuff works fine and the gadgets that I build work OK. But some of it is dodgy (even fake) and that's where the fun starts!
I like to use solar panels to power my workshop. This free energy is low voltage, so it's safe (mostly).

That is one big LED. Many LED chips inside that 100w LED. The only problem is the high current draw.

Why did you not check the amps and volts while ON?

It is important to note, that the V-I curve of LEDs is very temperature dependent.

Awesome build! I had no idea that LED's like that were available at such a low price point.

I have to admire the fact that you take the time to convert currencies to American dollars. Thank you!

You should have tested it at night time so we could see how it worked

Using two truck batteries would give a longer service life. Forklift battery with a trolley even better..

Power LEDs require constant current control. means as it gets hot it will change its internal resistance and what that means is you have to reduce the power or else it will get damaged. that's the reason it gets hot and changes the color. make it short your led will get damaged after you leave it for a while. I liked the way you assembled good job.

I'd only consider it "under $10" if I already had a bunch of ryobi batteries laying around. A more accurate description would be "100W flashlight for under $150".

I think it's a good idea to use PWM to pulse the LED on a duty cycle so it doesn't get too hot while maintaining brightness :)
