Introduction: 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!
Step 1: Parts
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
Step 2: Wrap the LED Strip
The LED strip is self-adhesive. Solder the wire to the end of the strip and wrapp the led strip around the wooden stick.
Step 3: Fixing the 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.
Step 4: Testing the Lamp
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.
