25x14.5mm Wide Surface Mount LED Channel — Aluminum Profile for 12mm Strip
Model: DL-1201

Overview
The 25x14.5mm Surface Mount LED Channel (model DL-1201) is a 6063 anodized aluminum LED profile — also searched as LED channel, LED extrusion or aluminum channel for LED strip lights — designed for Surface Mounted installation. The housing works as a heat sink for 24V and 48V high-power LED strips, while the PC diffuser (frosted, milky or transparent) hides the LEDs and delivers dot-free, uniform light. It accepts LED strips from 5mm to 12mm PCB width and is supplied in 0.5m to 4m lengths, cut to custom sizes on request. Every channel ships with end caps, mounting clips and connectors, so installers can complete under cabinet lighting, shelf lighting and ceiling linear runs without extra hardware. Pair it with DENO high-density 240 LEDs/m SMD or COB strips for a completely spot-free line of light in architectural and commercial LED lighting projects.
Description
Engineered with a 25x14.5mm surface mount design, this aluminum profile accommodates 12mm PCB LED strip light installations for commercial lighting applications. Constructed from durable AL6063-T5 aluminum, the channel provides superior heat dissipation to protect 2835 SMD LEDs and maintain luminous efficiency. The DL-1201 housing supports dimmable constant voltage DC 24V configurations with high-density tape lights of 120 LEDs per meter or above. Available in standard lengths from 0.5m to 4m, we provide OEM custom lengths and accessories for wholesale project supply.

Applications
- Cove lighting & recessed ceiling lines — Mounts continuous LED strip runs into coves, ceiling recesses and drywall joints so the fixture reads as a clean line of light instead of a visible strip.
- Heat management for high-power strips — The aluminium body acts as a heat sink, keeping LED junction temperature down and protecting lumen maintenance over the strip's rated life.
- Shelf-edge & display-case lighting — Compact channel sections fit shelf edges, glass cabinets and display joinery where the strip must stay hidden but serviceable.
- Diffused, dot-free finish — The frosted cover blends individual LEDs into an even line, which matters most on high-density and COB strips viewed at close range.

Pair With High-Power SMD LED Strips
The 6063 aluminum body acts as a heat sink, so this LED channel can safely run higher-wattage SMD LED strips — pair it with a high-lumen SMD strip and the frosted PC cover will deliver bright, evenly diffused light.
This channel accepts LED strips up to 12mm wide — its inner width leaves the 2mm clearance needed to seat the tape, so only strips at or below that width are listed.

Frequently Asked Questions
What LED strip width fits the 25x14.5mm Surface Mount LED Channel?
It fits LED strips from 5mm to 12mm PCB width, with 8mm and 10mm strips being the most common choice for this surface mount led channel. Check the inner channel width on the drawing before ordering, and allow 0.5mm clearance for the strip adhesive.
Which diffuser should I choose — frosted, milky or transparent?
Choose frosted for the best balance of diffusion and output, milky when you need to fully hide LED dots at short viewing distance, and transparent only when maximum lumen output matters more than glare control. Frosted covers are the default for under cabinet lighting, shelf lighting and ceiling linear runs.
How is this aluminum profile installed?
It is surface mounted with the supplied clips or screws every 400–500mm, then the strip is fitted and the diffuser snapped on. No recess or carpentry work is required.
Can this LED channel be cut to custom lengths?
Yes. Standard lengths are 0.5m to 4m and the aluminum extrusion can be cut with a miter saw on site, or pre-cut to your project dimensions at the factory. Cut the LED strip only at its marked cutting unit so every segment still lights up.
Does the aluminum profile work as a heat sink for high-power strips?
Yes. The 6063 aluminum body conducts heat away from the FPCB and keeps the LED junction temperature down, which is required for 24V and 48V strips above roughly 14W/m. Running high-power strips without a channel shortens lumen maintenance and shifts colour over time.
