Most pre-lit fiber optic Christmas trees are sold in common heights of about 5 ft, 6 ft, and 7 ft. Listings typically stick to those standard sizes, though availability can vary by model and retailer.
Fiber optic trees combine fiber optic strands with LED light sources that illuminate the tips. Common color options in listings include multicolored and color-changing LEDs, producing single-color, multi-color, or cycling effects depending on the model.
Many models offer multiple lighting modes. Common sequences listed include Combination, Waves, Sequential, Slo-Glo, Chasing/Flash, Slow Fade, Twinkle/Flash, and Steady On.
Common extras include a metal tree stand. Some listings also include gloves, spare lamps, a user guide, and decorative toppers or snowflake-shaped light covers — availability varies by model.
Intended use depends on the model. Most listings specify indoor use, at least one notes indoor/outdoor capability, and some describe UL certification and state indoor-only approval. Check each product’s listing for its specific usage rating.
