Connectors join strips and wires. Controllers decide color, brightness, and effects. Buying the wrong one is the most common mistake. This guide explains the types. For ready kits, see our lists of strips with remote and smart strips.
The Short Version
Match three things: the strip’s voltage, its pin count (single color, RGB, RGBW, addressable), and its width. A controller for the wrong strip type will not work, and some will damage the strip.
Connectors
- Clip connectors: no soldering; match width (listings mention 8 mm and 10 mm) and pin count
- Soldered joints: permanent and low profile
- DC barrel plugs: common between the supply and strip (5.5 x 2.1 mm in several listings)
- JST connectors: used on addressable strips
Controllers
| Type | What it does | Good for |
|---|---|---|
| IR remote | Basic color and brightness; needs line of sight | Simple kits |
| RF remote | Works without line of sight, longer range | Rooms and cabinets |
| Bluetooth app | Colors, scenes, timers within phone range | Most bedroom kits |
| Wi-Fi app | Remote control and voice assistants | Smart homes |
| Dimmer | Brightness only | Single-color strips |
| DIY controller | Programmable effects | Addressable strips (BTF-LIGHTING and SEZO listings name compatible controllers) |
Matching Guide
- Single-color strip: a dimmer or white controller
- RGB strip: an RGB controller
- RGBW and RGB+CCT: a controller with matching channels
- Addressable strip: a controller made for addressable strips; a regular RGB controller will not work

Frequently Asked Questions
Can I use any remote with any strip?
No. The controller and strip must match in voltage and type.
What if my remote stops working?
Replace the batteries first, then see our troubleshooting guide.
Do I need a controller for a kit?
Kits include one. Strip-only listings usually do not.
Safety note: low-voltage LED strips are safer to handle than mains wiring, but their power supplies plug into household power. Use the supply in your kit or one that matches the strip’s voltage and wattage, keep it dry, and follow the manual. Anything that connects to a household circuit should be done by a licensed electrician.
