How to make a rectangular infrared LED floodlight
LED lights come in a multitude of colours. (green led image by Albert Lozano from

A rectangular infrared LED floodlight is can be created using infrared LED light strips. LED light strips are rows of LED lights. These strips make connecting multiple LEDs simple. The rectangular flood light can be as large as you like and can contain as many LEDs as you like. LEDs are inexpensive, consume little power, emit little heat and are durable.

  1. 1

    Select a size for the flood light. Cut a piece of plywood to fit those dimensions. The entire piece of wood can be covered with LEDs.

  2. 2

    Purchase infrared LED light strips. LED light strips can contain a few to hundreds of LED lights. Purchase enough light strips to cover your plywood rectangle. Measure out how many LED light strips it will take to cover the entire piece of wood.

  3. 3

    Super glue the LED light strips to the wood. Ensure there is enough room to run each light strip wire to the control unit. Drill a hole right where the LED wire meets the wood, then fish the wire through to the back of the wood. The hole can be very small (1/4 inch.) This will keep the front of the LED floodlight free from wires. Wait for the superglue to dry. The front of the LED floodlight should be covered in LEDs.

  4. 4

    Attach all the LED wires to the LED control unit. This control switch will turn the flood light on and off and will either be powered by batteries or from an outlet; depending on which model is purchased.
