DIY Cheap Waterproof LED Lamp

LED lamps are long lasting and very economical. But they are still expensive. Here's how I made a 12V LED lamp, using a LED strip and discarded plastic jar. The lamp costed less than $1 to make and is bright enough to read a book and light up a room!

Here are the parts you need: plastic jar, wooden stick, some wire and LED tape. The LED tape is seld-adhesive, you can buy it on Ebay or any electronics store. In my case I used half a meter V-tac 3528 that costed $0.80

The LED strip is self-adhesive. Solder the wire to the end of the strip and wrapp the led strip around the wooden stick.

Fix the wooden stick to the cap with a screw. Run the wire through a hole on top. You can put some silicone on both places to make it waterproof.

Here's how the stick and the finished lamp glows into the dark. It consumes just 12V/135.5 mA! You can use it as 12V camping light attached to the car battery, or at home, with 12V adaptor.
