66ft Red and Green Christmas Lights, 640 LED Icicle Lights - Twinkle

In this review of the 66ft Red and Green Christmas Lights, the bottom line is simple: these lights are for decorators who want a long, high-density icicle string with vivid red and green LEDs and flexible lighting patterns. They excel at creating an immediate festive impact along eaves, porches, windows, and fences thanks to 120 vertical strands on a 66 ft main line and 8 selectable modes. The review finds them easy to install and energy efficient thanks to a low-voltage UL certified adapter, while durability concerns raised by some customers mean shoppers should consider placement and plug protection.

Key Features

• Length and density: The 66 ft main string with 120 vertical strands delivers a high-density icicle look that covers long eaves or fences without multiple short runs.
• 8 lighting modes: Eight modes including Combination, In Waves, Sequential, Slo-Glo, Chasing/Flash, Slow Fade, Twinkle/Flash and Steady On provide versatile effects for different moods and events.
• Connectable design: End-to-end connection supports linking up to three strings together so larger displays can be built from a single controller and adapter.
• Low-voltage and UL certified: The adapter outputs 29V at 6W with UL certification, offering cooler operation and energy savings compared with higher-voltage sets.
• Memory and timer: Memory recalls the last mode on restart and a hold-button timer (6 hours on, 18 hours off) simplifies nightly operation without manual resetting.
• Weather resistance: Sealed LED beads, thicker gauge wire and IP44 waterproofing on the light string make the set suitable for rain and snow; the plug is not waterproof and needs protection.

Who It's For

This set is aimed at homeowners, event decorators, and anyone who needs a long, continuous icicle light run with a festive red-and-green color scheme. The 66 ft length and connectable capability suit porches, gutters, large windows, fences and commercial storefronts that benefit from a continuous, high-density display.

Shoppers who need fully weatherproof plugs or expect the lights to last for many seasons without any issues should take care: some customers report mixed functionality and durability concerns. If you require a guaranteed heavy-duty commercial grade set or need a waterproof plug, consider alternatives designed specifically for those needs.
