Introduction: Make a 1000w Equiv. LED Flashlight!
Here's how to make a phenomenally bright 1000w eqiv. LED flashlight!
It's designed to be operated with just one hand, with easy control of brightness, and can be powered by either batteries or an AC adapter.
Can be built for around £25 if you get the CPU cooler for cheap.

I've made this project and it is almost finished, but I have a question about the power output/current consumption.
I have a power meter connected to the input, and it shows (with the LED regulated to the maximum brightness) a current consumption of 2.1A, wich multiplied by the battery voltage (3S LiPo @11,4V) equals to 24W, which is very far from the power announced for the LED that I bought - 100W - and even for the target of this instructable.
The step up DC-DC converter is regulated correctly to the 30V output required to feed the LED.
Can you please tell me what might be wrong?
