What Are LED Strip Lights and Why Should You Use Them?
LED strip lights — also called tape lights or ribbon lights — are flexible circuit boards lined with surface-mount LEDs. I've installed them in kitchens, bedrooms, living rooms, home theaters, and outdoor patios. They're the most versatile lighting product I've used. You can cut them to length, stick them anywhere, control them with a phone app, and change colors on demand. In 2026, LED strips have become affordable enough that there's no reason not to have them in at least one room of your house. Here's everything I've learned from installing over 50 meters of LED strips across multiple homes.
RGB vs RGBW vs Addressable: Which LED Strip Type Should You Choose?
The three main types serve different purposes. RGB strips (red, green, blue) produce any color by mixing these three channels. RGBW adds a dedicated white LED chip for better white light. Addressable strips (WS2812B, SK6812, APA102) let you control each individual LED's color — creating animations, gradients, and chasing effects. I use RGBW strips for under-cabinet and accent lighting where I need good quality white light. I use addressable strips for TV backlighting and ambient effects. Standard RGB strips are fine for party lighting but the white light is poor — it's a mix of the three colors that looks purple more than white. My RGB vs Addressable guide covers the technical differences in detail.
How Do You Install LED Strip Lights Correctly?
The 3M adhesive on most LED strips fails within 6 months if applied to unprepared surfaces. I've had strips fall from under-cabinets twice before learning the trick: clean the surface with isopropyl alcohol, apply the strip when the room is above 65°F, and use mounting clips ($5 for a pack of 20) in addition to the adhesive. Cutting strips is straightforward — they have cut lines every 3-6 LEDs (usually marked with a scissor icon and copper pads). Soldering connectors gives a more reliable connection than the snap-on clip connectors, which I've had fail on high-current RGBW strips. My installation guide has step-by-step photos of each technique.
What Power Supply Do LED Strips Need?
This is where most people get stuck. 12V and 24V are the two common voltages. 12V is more common for short runs (under 5 meters). 24V handles longer runs (up to 10 meters) with less voltage drop. The power supply must be rated for at least 20% more than the strip's maximum draw. A 5-meter 12V RGBW strip drawing 3A needs a 5V 3.6A — round up to 5A to be safe. I use Mean Well power supplies ($15-30) for permanent installations — they're reliable and have proper safety certifications. Cheap no-name supplies can fail and damage the strips. My power supply guide includes a calculator table for common strip lengths.
Where Do LED Strip Lights Work Best at Home?
I've tested LED strips in almost every application. Under-cabinet kitchen lighting is the most useful — it eliminates countertop shadows and costs about $30 for a 5-meter RGBW strip and power supply. TV backlighting (bias lighting) reduces eye strain and makes the TV look better — a 2-meter USB-powered strip costs $15. Bedroom ceiling coves create a stunning ambient glow with 4 meters of warm white (2700K) strip. Outdoor patio strips need an IP65 waterproof rating. I use Govee RGBIC strips for accent walls and Philips Hue gradient strips for TV backlighting. My applications guide covers all of these with specific product recommendations and installation tips.
