The "Stars" That these LEDs come with are NOT the heatsink. Its just a means to screw onto an actual heatsink. Also, I can see that the heat of LED which is pasted directly on the battery has caused battery to swell. Please discontinue use or battery may explode.

I think your title is a little misleading. I highly doubt that this brightest flashlight ever.

Well, maybe it's the brightest to him (the author). Btw, I also highly doubt that the battery is Li-ion, it should be Li-po for that appearance.

I mean it's the brightest to its size

No over-discharge protection for the battery?

it's dangerous to not current limit LEDs. You should be using a resistor in series with the LED.

thank you.but my led is 3.7 volts,but if you use standard led you should use a 1.5 ohms resistor in series.
