Pre-lit artificial Christmas tree uses dense PVC branches with 680, 1098, or 1528 tips to create a full green silhouette and distribute 700, 1000, or 1200 LED lights for even illumination. Three lighting modes and four brightness levels let you fine tune the look for different rooms and times of day. A timer keeps the lights on for 6 hours and off for 18 hours, while a built-in memory function preserves your last light setting for the next use.
