What to Consider Before Buying Christmas Tree Lights Before you buy your Christmas tree lights, it's important to review several important factors to make sure that you get the most safe, brightest and aesthetically pleasing version of your lights. 1. Brightness & Color Temperature The brightness of Christmas lights is rated on the number of lumens not on the number of watts consumed. LEDs generate more lumens per watt, which means that they generate brighter light using less electricity. Warm white (2700K–3000K): Cozy, golden glow. Cool white (4000K+): Crisp and modern. RGB/RGBIC lights: Millions of colors for animated displays. If dynamic effects are desired and they need to be very flexible, then RGBIC (independent chip control) provides advanced flowing effects and multiple colors. 2. Length & Number of Bulbs The number of LED lights needed per 2 ft. of tree height is approximately 100 luminescent lights. Smaller trees require one strand, while taller or bushier trees require several strands to give them full featured, festive covering and added sparkle. 3. Bulb Type: LED vs. Incandescent vs. Filament When it comes to selecting bulb types, LED is energy efficient, long life and does not get as hot to the touch, in many cases, yields smart control features as well. Incandescent is good in terms of a warm, vintage look but they last less and heat more. Filament-style LEDs provide an amalgamation of efficiency of LED and the traditional look of an incandescent appliance. 4. Smart Features & Control Modern smart tree lights offer: Bluetooth or Wi-Fi connectivity App control Voice control (Alexa, Google Home, Matter) Preset scenes and animations Schedules and timers Using these features you are able to customize what your display looks like without laying your finger on the tree. 5. Durability & IP Rating for Outdoor Use For outdoors or partially exposed trees, look for the lights that are rated with IP65 and more which means extremely resistant to rain and dust. Note: Power adapter usually is less waterproof (e.g. ip44), so they must be kept dry. 6. Safety & Certifications Choose lights with UL or ETL certification, low-voltage transformers, and insulated wiring to ensure safe indoor use — especially around children and pets. Part 3.
