Description
16x16mm aluminium corner profile, 1-metre length, black anodised finish, supplied with a milky opal diffuser. It mounts at 45 degrees across internal corners and takes LED strip up to 10mm wide. The black body reads as a dark shadow line when unlit, so the fitting disappears against dark joinery, media walls and slatted panels until you switch it on.
- Dimensions: 16 x 16mm
- Max tape width: 10mm
- Material: Black anodised aluminium
- End caps included
- Mounting clips and screws included
Where a black corner profile works best
- Dark joinery and media walls: the profile vanishes against black or walnut panels instead of drawing a silver line across them.
- Slatted feature walls: run it along the top edge so light rakes down the battens, invisible at standing height.
- Display cabinets: a dark channel keeps the eye on what is lit rather than on the fitting.
- Under-cabinet runs: sits in the wall-to-cabinet corner, angling light across the worktop rather than at the splashback.
Fitting
Cut to length with a fine-tooth hacksaw or mitre saw, screw the supplied clips to the surface, stick the LED strip to the internal face, then clip the profile on and press the diffuser and end caps home. Cut the diffuser separately from the aluminium — sawing both together cracks the cover. The aluminium body draws heat away from the LEDs, which is what protects their output over time. Covered by a 7-year guarantee.

Frequently Asked Questions
What is the difference between IP65, IP67, and IP68?
IP65 handles surface splashes only and is not suitable for UK outdoor conditions or bathroom wet zones under BS7671. IP67 is rated for temporary immersion and covers outdoor garden installations, most bathroom zones, and exposed architectural features. IP68 handles continuous submersion for ponds, fountains, and fully exposed outdoor applications. For most UK garden and decking projects, IP67 is the correct choice.
Can I cut this product to a custom length?
Yes. ATOM LED products can be cut at the marked cut points without voiding the warranty. Many competitors restrict cuts to 50–100mm intervals, which wastes offcuts on tight custom runs. Use sharp scissors or a craft knife for a clean cut, then seal the end with a suitable end cap.
What size driver do I need?
Multiply the total metres by the wattage per metre, then add 20% headroom. For example: 10 metres of 24V neon flex at 9W/m = 90W total, so you need a minimum 108W driver. Never load a driver above 80% capacity for long-term reliability.
Should I choose 12V, 24V, or 48V?
Choose 12V for caravans, cars, boats, and any project powered by a 12V battery. Choose 24V for most home and trade installs where you need dependable run length with lower voltage drop. Choose 48V for longer architectural runs where extra distance and single-feed flexibility matter. For underwater or submerged installs, use IP68 Waterproof lights and the correct driver for that product; do not use 48V underwater.
What is your warranty?
ATOM LED offers product-specific warranties: up to 7 years on single-colour COB strip, 5 years on RGB and RGBW COB strip, and 4 years on LED neon flex. The warranty covers manufacturing defects. Call 01952 370028 for warranty claims.
Do you offer free delivery?
Yes. Free UK delivery on 97% of products via Royal Mail 48-hour tracked. Free next day delivery on Mainland UK orders over £90 (order by 1pm, Mon–Fri).
