RGB LED Strip Lights: How to Choose the Length & Set Them Up
RGB LED strip, measuring tape and connectors arranged for room installation

Quick answer: RGB LED strip lights are flexible, peel-and-stick light tape that can shine in millions of colors, controlled by a remote. They plug into a power adapter (they’re mains-powered, not solar), come in rolls from 50 to 200 ft, and can be cut to length at marked points. Stick them along a ceiling, behind a desk, or under cabinets for a quick, wire-free-looking color upgrade.

RGB strip lights are the fastest way to change the whole mood of a room — no rewiring, no fixtures, just a roll of adhesive tape and a remote. Here’s how to choose the right length, set them up cleanly, and get the most out of the color modes.

What are RGB LED strip lights?

Our RGB LED Strip Lights are a long, flexible strip of color-changing LEDs with an adhesive backing. “RGB” means the LEDs mix red, green, and blue to produce the full color spectrum, so one strip can glow any color you like. The strip plugs into an included power adapter and control box, and you change colors and effects with the remote. Unlike the solar lights elsewhere on our site, these are mains-powered — they need a nearby outlet.

How many feet do you need?

The strip comes in four roll lengths — 50, 100, 150, and 200 ft — so you can match it to the job:

  • 50 ft — a single room: one ceiling perimeter, a bed frame, or a desk.
  • 100 ft — larger rooms, or a room plus accent borders.
  • 150–200 ft — whole-room ceiling borders, home theaters, or multiple areas.

Measure the total run you want to cover before ordering. The strip is cuttable at marked points, so you can trim it to fit exactly — just note that cut sections can’t easily be reconnected without tools, so plan your cuts.

Remote control, colors, and modes

Everything is controlled by the included remote — there’s no app to set up. You can:

  • Pick any color across the full RGB spectrum.
  • Adjust brightness to suit the room.
  • Switch between preset effects like fade, jump, and static — from a slow color drift to a held single color.

How to install RGB strip lights cleanly

  • Start with a dry, clean, smooth surface — wipe down the wall, shelf, or desk first so the adhesive grips. Avoid rough or oily surfaces.
  • Plan the path — peel a section at a time and press as you go, following corners rather than forcing sharp bends (tight kinks can damage the strip).
  • Connect the power — plug the strip into the control box and power adapter, keeping the control box and plug away from moisture.
  • Cut to fit — trim only at the marked cut points if you need a shorter run.

Where to use them

  • Bedrooms & gaming rooms — behind the headboard, desk, or monitor for a backlit glow.
  • Living rooms & home theaters — along shelving or behind the TV to reduce glare.
  • Kitchens — under-cabinet accent lighting.
  • Ceiling & window borders — outline a room for an even wash of color.
  • Covered patios & balconies — these work for indoor and covered outdoor use; keep the control box and plug dry.

Frequently asked questions

Are these strip lights solar or plug-in?

They are plug-in (mains-powered). The strip connects to an included power adapter and control box, so you’ll need an outlet nearby — unlike the solar lights elsewhere on our site.

How many feet do I need?

Rolls come in 50, 100, 150, and 200 ft. Measure the full run you want to cover first. A single room usually needs 50 ft; larger spaces, ceiling borders, or home theaters do better with 100 ft or more.

Can I cut the strip to size?

Yes, the strip can be cut at the marked cut points to fit your space. Keep in mind that cut sections can’t easily be reconnected without tools, so plan where you cut before trimming.

What colors and effects can I set?

The LEDs cover the full RGB spectrum, so you can choose any color. The remote also adjusts brightness and switches between preset modes like fade, jump, and static (a held single color).

Can I use them outdoors?

They’re rated for indoor and covered outdoor use, such as a covered patio or balcony. Keep the control box and plug away from moisture, and don’t expose the connections to direct rain.
