LightInTheBox offers the ZDM Waterproof 120-watt 600-LED 5050 RGB LED Strip Set for $25 with free shipping. That's $14 under the lowest price we could find for a similar set elsewhere. This set includes four 16.4-Foot 150-LED light strips, a 44-key remote, and a 1BIN4 connector adapter (attaches fours strips to the power source.)

Note: This item ships from China and may take three to four weeks to arrive. Uncheck "Add Shipping Insurance to your order" during checkout to remove the 49-cent fee.
