12V 5050 flexible LED strips deliver the brightest output in our flexible strip lineup. The 5050 SMD chip (5.0×5.0mm) packs three LED dies into a single package, producing roughly 12–18 lumens per chip — two to three times what a single-die 3528 chip delivers. Our non-waterproof 5050 strips feature 30 LEDs per meter (150 LEDs per 5-meter reel) on a flexible PCB with 3M adhesive backing, drawing approximately 7.2W per meter. This is the strip to choose when you need LED strip lighting that makes an impact: bright enough for task-adjacent illumination, signage backlighting, architectural accent walls, and bold RGB color effects.

These strips are non-waterproof — the 5050 chips and copper traces are exposed on the flexible PCB, making the strip thin, flexible, and easy to install in dry indoor environments. Use standard 5050 strips under kitchen cabinets (away from sinks), behind entertainment centers, along desk edges, inside PC cases, beneath bar counters, in retail display cases, behind mirrors, and along ceiling coves. For any installation where moisture is a concern — outdoor, bathroom, kitchen splash zones, boats, RVs — use the waterproof 5050 strip instead.

The 5050 platform is the home of RGB color mixing. Each RGB 5050 chip contains one red, one green, and one blue die with independent electrical connections. An RGB controller sits between the 12V power supply and the strip, allowing you to select any color in the visible spectrum, set static moods, program color-cycling and fading sequences, adjust brightness per channel, and in many cases sync lighting to music or a DMX board. Single-color 5050 strips (warm white, cool white, red, green, blue) wire all three dies in the same color for maximum single-color brightness without needing a controller — connect straight to 12V and go.

Brightness and color temperature choices matter for the look and feel of your installation. Warm white 5050 strips (approximately 3000–3500K) produce a rich, incandescent-like glow suited for living rooms, dining rooms, bars, wine cellars, and hospitality spaces. Cool white (approximately 5500–6500K) delivers a crisp, daylight-like output for kitchens, garages, workshops, retail displays, and anywhere you want a clean, bright white. RGB strips in full-white mode (all three channels at 100%) produce a slightly cooler white than a dedicated cool-white strip because the combined red+green+blue spectrum differs from a phosphor-converted white LED.

Every 5050 strip can be cut to length at marked cut lines every 3 LEDs (every 10cm). Cut between the copper solder pads with ordinary scissors. Each cut segment is independently functional — connect to 12V DC and it illuminates immediately. To rejoin segments, make turns, or extend a run, use solderless strip connectors: 2-pin for single-color strips, 4-pin for RGB strips. These connectors clip onto the exposed copper pads for a secure electrical connection without soldering. Browse our wire, switches, and connectors category for compatible connectors, extension cables, DC barrel jack pigtails, and inline switches.

Power supply sizing is critical because 5050 strips draw more current than 3528 strips. A full 5-meter reel at 7.2W/m draws 36W; use a 45W or 50W 12V DC power supply to provide adequate margin. For RGB strips, always calculate based on maximum draw (all three channels at full brightness = white mode), even if you primarily use single-color modes. Undersizing the power supply causes dimming, color shift, and premature supply failure. For multi-strip installations, size the supply for the combined total wattage of all connected strips plus 15–20% headroom, or use multiple supplies, one per strip run.

Voltage drop management matters more on 5050 strips than on 3528 because of the higher current draw. Keep single-end-fed runs to 5 meters or less. For runs over 3 meters from a single power feed, you will notice the LEDs at the far end appear dimmer than those near the feed point. The solution is to inject power from both ends of the strip, or from a midpoint. For installations exceeding 5 meters, never daisy-chain reels end to end — run separate feed wires from the power supply to each reel. Use 16–18 AWG wire for the supply leads between the power supply and the strip to minimize additional voltage loss. For precise short lengths, check our LED strips by the section category for pre-cut 5050 sections. For softer ambient lighting at lower power, consider our 3528 LED strips.

Frequently Asked Questions

A single 5050 chip produces 12–18 lumens compared to 5–7 lumens from a 3528 chip — roughly 2–3 times brighter per LED. While 5050 strips have fewer LEDs per meter (30 vs. 60), each LED is individually much brighter. The overall visual impression is a noticeably brighter strip. Use 5050 when you need the strip to serve as a functional light source (task lighting, signage, architectural accents), and 3528 for softer ambient/decorative effects.
Technically yes — set all three RGB channels to 100% and the strip produces white light. However, this RGB-mixed white has a slightly different color spectrum than a dedicated warm white or cool white strip. The mixed white can appear slightly pink or lavender compared to a pure white LED. If your primary use is white lighting, a dedicated warm white or cool white 5050 strip will produce a more natural, consistent white. RGB strips are best when you want the flexibility to change colors.
RGB 5050 strips use 4-pin connectors — one pin for the common 12V anode and one each for the red, green, and blue cathode channels. Single-color 5050 strips use standard 2-pin connectors (positive and negative), the same type used with 3528 strips. Make sure you buy the correct connector type for your strip. Our wire, switches, and connectors category stocks both 2-pin and 4-pin solderless strip connectors, corner connectors, and extension cables.
Yes, because they draw more power (7.2W/m vs. 4.8W/m for 3528). The additional heat is not dangerous but can reduce LED lifespan if the strip cannot dissipate it. For best thermal performance, mount 5050 strips on aluminum LED channel extrusions, which act as heat sinks. Avoid mounting on insulated surfaces (foam board, fabric, thermal ceiling tiles) that trap heat. In well-ventilated locations or on metal surfaces, heat is not a concern at normal 12V operating conditions.
Yes. For single-color strips, use a 12V PWM (pulse-width modulation) dimmer inline between the power supply and the strip. For RGB strips, the RGB controller itself provides dimming functionality on each channel independently, plus a master brightness control. PWM dimmers switch the power on and off thousands of times per second, producing smooth dimming without color shift. Never use a standard household TRIAC dimmer (designed for 120V AC incandescent bulbs) with 12V DC LED strips.
The recommended maximum is 5 meters (one full reel) per single power connection. Voltage drop on the thin copper traces causes the far-end LEDs to dim visibly on runs over 3 meters from a single feed. For even brightness across a full 5-meter reel, inject 12V from both ends. For installations exceeding 5 meters total, run separate feed wires from the supply to each 5-meter strip segment — never chain reels end to end through the strip’s own traces.
