Description
Long-Run Under Cabinet COB LED Strip supports larger kitchens, continuous cabinet walls and commercial joinery where fewer feed points are preferred. Its smooth COB light line reduces visible spotting on worktops and reflective splashbacks.
Up to 20m continuous run
This 24V, 10mm strip uses 480 LEDs per metre at 7.5W/m. Select a white tone from 2700K to 6500K and a length from 1m–20m. Cut only at the marked 50mm (5cm) intervals; availability follows the selected source length.
Plan the installation

Which colour temperature should I choose? 2700K and 3000K feel warm and relaxed; 4000K gives balanced preparation light; 5000K and 6500K create a cooler, high-clarity appearance.
What else is needed? Use a compatible 24V constant-voltage power supply and a 10mm aluminium profile. A controller is optional for dimming. Power supplies, profiles and controls are sold separately.
Where can it be installed? IP20 is for dry indoor locations. Keep the strip away from sinks, steam and splash zones, and have mains-side work completed by a competent installer.
How should a long run be powered? Calculate the full connected load, allow the power supply manufacturer’s recommended capacity margin and follow the correct cable-sizing and voltage-drop plan.
Made for your cabinetry: choose the required metre length, or use our Made to Measure service for a bespoke, custom-cut lighting specification.

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).
