Let’s be honest: LED strip lights have upped their game massively in Mzansi homes—but without the right support, they sometimes don’t look nearly as sleek as they could. That’s where aluminium profiles come in. These clever bits of kit not only make your lighting look pro, they also help prolong the life of your LED strips.

Why aluminium profiles matter with LED strips
Let’s face it—stick-on LED strips on their own can easily end up sagging, overheating, or giving off that messy DIY vibe. Aluminium extrusion profiles fix all that in one go. Besides looking clean and polished, they help your lights run cooler, last longer, and offer that diffused, pleasant glow everyone’s after.
Function meets flair
Installed correctly, aluminium profiles convert your LED strip setup into top-tier architectural lighting. From delicate toe-kick skirtboards to dramatic hallway uplighting, they help achieve consistent, high-end finishes. Many use frosted diffusers to soften harsh diodes and reduce glare—a big win for modern South African interiors where open-plan is king.
Pro Tip: If you’re installing around a curved cornice or along uneven brick, use our flexible RGB LED strip with surface aluminium profile—it’s bendy and beautiful.
Done right, they add durability
We’ve seen this happen often: someone mounts LED strips under kitchen cabinets, gets a little braai smoke exposure (because who doesn’t love a lamp chop flip with ambiance?), and bam—yellowing adhesive or warped backing. Aluminium profiles shield against that. The aluminium acts as a heat sink, and the PC cover protects your lights from grease, dust and even the odd tomato sauce squirt.
Recessed, surface, or corner? Let’s break it down
The choice depends on two things: look and location. Recessed types sit flush with the surface—ideal for shelving or tiled installation. Surface-mounted profiles are versatile and easiest to retrofit. Corners are specialised but great for accent lighting.
| Feature | Recessed | Surface |
|---|---|---|
| Installation | Needs routing or cutting into surface | Mounts directly on top |
| Finish | Ultra sleek, hidden look | Sits proud of surface |
| Best Use | Floors, walls, cabinetry | Kitchens, garages, halls |
| Maintenance | Lower access for cleaning | Easy to remove/replace |
Choosing the right size
This part’s crucial. Aluminium profiles come in widths from ±8mm to 30mm+. Check the width of your LED strip before you shop. For example, our popular 12V 5050 Ultra Bright LED Strip fits snugly into most standard 16mm wide profiles—but for twin-run installations, go wider.
Do they play well with energy efficiency?
You bet! Especially in the South African context, where energy-efficient lighting strategies go hand-in-hand with aesthetic choices. Aluminium improves thermal flow, helping lights draw less wattage under stress. Efficient and elegant—dop en chop approved.
And when Eskom leaves you in the lurch (as it does, regularly), aluminium profiles won’t dislodge from heat tape fatigue. They’re made to last—as long as your inverter holds up anyway!
Where to install them?
Honestly—anywhere! But here are top SA picks for aluminium profile lighting:
- Bedrooms: Cornice-mounted LED profiles keep the mood romantic but practical.
- Kitchens: Undercabinet LED strips in profiles make prepping sosaties safer.
- Living rooms: TV units or wall accents with diffused profiles deliver instant "magazine home" vibes.
- Braai areas: Opt for water-resistant aluminium profiles outdoors (just watch for rain).

Frequently Asked Questions
What’s the main purpose of aluminium profiles for LED strips?
They protect LED strips, allow better heat dissipation, and create a neat, finished look with diffused lighting options.
Are aluminium profiles necessary indoors?
While not strictly necessary, they’re highly recommended for a polished, longer-lasting, and safer LED strip installation indoors.
Can I cut aluminium profiles to custom lengths?
Yes, most standard profiles are cuttable using a hacksaw or mitre saw. Just deburr the edges before installing the diffuser.
Do aluminium profiles come with mounting clips?
Yes! Most premium-grade profiles include mounting clips and end caps for clean installs and easy removal later.
Which profile should I use for cornice or ceiling lighting?
Use surface-mounted or angled corner profiles with frosted covers to produce indirect, ambient glow from above.
Can I use aluminium profiles outdoors in SA?
Yes, as long as they’re covered and the strip inside is IP-rated. Pair with a sealed diffuser for outdoor use.
What’s the best profile width for 5050 LED strips?
A profile with a 12-16 mm internal width is ideal for standard 5050 strips, allowing airflow without crowding the wiring.
Do profiles help during load shedding?
Absolutely. By stabilising strip mounting and reducing heat stress, they support smooth operation even on low-voltage backup systems.
