Available in Warm White, Cool White, Red, Blue, and Green, it gives you the choice between functional illumination and vibrant decorative effects. The 12V compatibility means it connects easily to your vehicle or leisure battery without additional converters, making it an ideal option for travel and outdoor projects where low-voltage lighting is required.

Built with high-quality LEDs, this single colour strip ensures long-lasting performance with consistent brightness and low power consumption, helping to preserve battery life. It can be cut to length at marked intervals, allowing for fully customised installations whether you’re lighting up a motorhome interior, caravan awning, boat cabin, or custom project.

With easy installation and a wide choice of colours, the 12V LED strip light is a practical and energy-efficient way to add dependable lighting to any 12V system.

FAQ's

What power supply size (e.g., is 30–40W enough) do I need for a 5m 12V strip?

Add up the strip’s total wattage (W/m × 5m), divide by 12V to get current, then choose a PSU with ~20–30% headroom; a 30–40W PSU only suits lower-power 12V strips (roughly up to ~24–30W total), not higher-brightness reels.

How to calculate voltage drop for 12V LED strips

Work out the current (total watts ÷ 12V), then estimate drop using Vdrop = I × R (where R is the round-trip resistance of your cable/strip conductors); if the far end noticeably dims or warms in color, shorten the run or add power injection.

How far can 12V single-colour strips run without voltage drop?

Many 12V strips start showing visible dimming by around a full 5m reel at 100% brightness, especially on higher-wattage types; for consistent output, plan injection every few meters or feed from both ends.

Can I cut 3528 strips and how to reconnect them?

Yes cut only at the marked cut lines, then reconnect by soldering the +/– pads (most reliable) or using the correct-width solderless clip for that strip type.

Differences between 3528 and 5050 single color LEDs

5050 LEDs are physically larger and typically brighter (and draw more power) than 3528, while 3528 strips are usually lower output, lower heat, and better for subtle accent lighting.

How to Waterproof an IP20 strip for outdoor use

The safest option is buying a factory Waterproof strip, but you can sleeve IP20 strip in a silicone tube/channel and fully seal ends and joints with adhesive-lined heat shrink + neutral-cure silicone, ensuring water can’t sit or wick into cut points.

Why inject power mid-run on longer cove installations?

Mid-run injection reduces voltage drop so brightness and color stay even, and it lowers the current carried through the strip’s thin copper traces, reducing heating and stress.

Which CCT (2700K vs 4000K) suits kitchen task lighting best?

4000K is usually better for task work because it looks cleaner and boosts perceived contrast, while 2700K feels warmer/cozier but can look more “yellow” on countertops.

How does CRI 80+ affect colour rendering in retail displays?

CRI 80+ is a decent baseline, but higher CRI generally makes products look more natural and accurate especially reds and skin tones so many retail setups prefer CRI 90+.

What lumen output (400 lm/m) works for under-cabinet brightness?

400 lm/m is typically fine for soft accent or low-level counter lighting, but for true task lighting many kitchens land closer to roughly 600–1000 lm/m depending on diffuser, mounting height, and countertop color.

Do IP65 silicone versions handle bathroom moisture effectively?

Usually yes for general bathroom humidity and splash zones (when installed and sealed properly), but they’re not automatically suitable for direct shower spray or submerged areas placement and proper sealing matter.

Which solderless clips extend strips without wiring skills?

Use clips that match your strip width (commonly 8mm/10mm), IP style (bare vs silicone-coated), and current rating; lever/lock-style connectors tend to hold more reliably than very small “snap” types.

How do aluminum profiles dissipate heat in recessed coves?

Aluminum profiles act as a heatsink, spreading LED heat over a larger surface so the strip runs cooler, which helps maintain brightness consistency and can significantly extend LED lifespan.
