this is our new helper for camping,mountain climbing,reading and sailing.it's also very cheap and it costs under a dollar.

Step 1: What Do You Need?

1-1w power led

2-3.7V 350mA li-ion battery

3-li-ion battery charger board(optional)

4-power led lens and holder(5^ or 45^)

5-small on\off switch

Step 2: Hot Glue the Power Led to the Battery

Step 3: Hot Glue the Switch

Step 4: Solder Them All Together

then add the lens and hot glue all the thing together.

Step 5: You're Done!

now you are done and you can test the flashlight as i tested the battery will last about an hour so it's good for the size of it.

I think your title is a little misleading. I highly doubt that this brightest flashlight ever.
<p>thanks.i will edit the title.thank you</p>
<p>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.</p>
<p>I mean it's the brightest to its size</p>
<p>No over-discharge protection for the battery?</p>
<p>it's dangerous to not current limit LEDs. You should be using a resistor in series with the LED.</p>
<p>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.</p>
<p>it's dangerous to not current limit LEDs. You should be using a resistor in series with the LED.</p>
<p>Long life to your LED !</p>
