120V LED COB Strip

Working with 120V AC power is a serious job. These 120V LED strip lights connect directly to your building's line voltage. If you aren't a licensed electrician or completely comfortable working with high voltage wiring, please hire one. It's not like plugging in a 12V wall adapter; mistakes can be dangerous.

That's right, you don't need a bulky external power supply. These 120V LED lights are often called 'driverless' because they have a small, built-in rectifier that converts AC to DC right on the strip. You just connect the special power cord directly to your 120V source. This makes them great for long, simple installations where hiding a driver would be a hassle.

The biggest advantage of a 120V LED tape light is its long run capability. You can run a single, continuous strip up to 164 feet (50 meters) with no noticeable voltage drop. The light at the end will be just as bright as the light at the beginning. With low-voltage DC cob strips, you can only run 98 feet (30 meters) max without injecting more power.

No, and this is a common mistake. Unlike 12V or 24V strips with cut points every inch, a 120V LED tape has much larger cut intervals, often every 20 or 40 inches (50cm or 100cm). The strip is wired in long sections, and cutting anywhere besides the marked scissor icon will cause that entire section to fail. Always measure twice and cut once, right on the line.

You'll need a compatible line-voltage AC dimmer. These 120V dimmable LED strips work with many standard wall dimmers, especially TRIAC or forward-phase models from brands like Lutron or Leviton. You cannot use the low-voltage DC PWM dimmers meant for 12V/24V strips. We have a selection of compatible high voltage dimmers.

Yes, our 120V LED strip lights outdoor models with an IP67 rating are perfect for landscape and exterior use. The IP67 rating means the strip is fully encased in a protective silicone jacket, making it waterproof against rain and jets of water. Just be sure to properly seal the power connection and the end cap with silicone glue to maintain that waterproof seal. We stock all the needed high voltage connectors.

For a 120V strip light, you should always use the included plastic or metal mounting clips screwed into the surface. Because these strips are heavier and thicker than low-voltage versions, relying on adhesive tape alone isn't enough, especially outdoors or on overhead surfaces. The clips provide a secure, permanent hold. You can also install them inside deeper aluminum channels for a cleaner look and better protection.

It's a simple trade-off: run length versus cut-ability. A 120V strip gives you massive run lengths from one plug, which is ideal for architectural coves or building outlines. A 24V strip requires drivers and has shorter max runs, but its tiny cut points let you build precise lengths for under-cabinet, display, or task lighting. For long and straight, 120V wins. For short and detailed, 24V is better.

Practically speaking, no. Our 110-120V LED strips are designed for the standard range of North American line voltage. Your wall outlet might provide 115V, 118V, or 121V depending on the grid load, and the strip will work perfectly fine across that whole range. The same applies to our 220-240V models for other regions. Don't sweat the exact number.

The best high voltage application for LED strip lights 120V is any long, continuous run. Think large commercial projects: hotel corridors, exterior building accents, landscape path lighting, long retail soffits, and expansive ceiling coves. Basically, any job where running low-voltage wiring and hiding multiple power supplies would be a huge cost and labor headache.
