DC 12V 24V SMD 3528 Flexible LED Strip Light

Tech specs at a glance

The ILED-FX-3528 is a flexible SMD 3528 LED strip in five brightness variants, each using standard 3.5 mm × 2.8 mm single-chip LED packages on a bendable printed circuit. It is controlled by a single-channel PWM dimmer — the entire strip changes brightness as one zone. Choose the variant that matches your lumen requirement and power budget.

Colour options

Seven colours are available: Red, Green, Blue, Yellow, Warm White, Cool White, and Commercial White. The saturated colours (R/G/B/Y) are chosen for accent and decorative lighting where a specific hue is needed. The white variants differ in colour temperature: Warm White (2700K–3000K) for residential ambience, Cool White (5500K–6500K) for task lighting and commercial spaces, and Commercial White (4000K) as a neutral middle ground used in offices and retail environments.

CRI >80 is standard across all variants. CRI >90 is available as an upgrade for white colour models only — specify it at order time. Saturated colours do not carry a CRI rating because CRI only applies to white light sources.

IP rating options

The FX-3528 comes in four IP variants: IP20 for dry indoor use, IP65 for splash-proof outdoor coverage, IP67 for temporary submersion, and IP68 for continuous underwater use. Each variant uses a different silicone coating, so do not mix IP ratings on the same run — the joints will not seal correctly and moisture will enter at the transition point.

Build and installation

The strip is mounted on a flexible PCB with a 3M adhesive backing — standard yellow, with red available as an option. It cuts every 25 mm along marked copper pads. Each roll includes a 15 cm output cable. Standard roll length is 5 metres; custom lengths are available on request.

For runs over 3 metres on compatible models, 24VDC is recommended to reduce voltage drop and maintain brightness at the far end. The 30 and 60 LEDs/m models are 12VDC only and work best for shorter runs under 3 metres. Always add 20% current margin when sizing your power supply to keep it running cool and extend its lifespan.

What is in the box

One 5 metre roll of the selected variant with the 15 cm input cable attached. The 3M backing is pre-applied and ready to stick once the surface is cleaned and dried. No controller or power supply is included — those are separate items.

What you need to supply

A 12VDC or 24VDC power supply rated for the total wattage of your strip run plus 20% headroom. A single-channel PWM dimmer — any standard LED dimmer that accepts the input voltage of your strip. Connectors or solder for joining strip sections end to end. Heat-shrink tubing or electrical tape for insulating cut-end copper contacts.

Where it gets used

Residential under-cabinet and shelf lighting — the 30 and 60 LEDs/m models are low-power and economical for kitchens, wardrobes, and display cases. Ceiling coves and architectural accent channels — the 120 and 240 LEDs/m models deliver even illumination with a 120° beam angle. Retail display backlighting and commercial signage — the 240 and 240D variants provide high brightness for light boxes and illuminated signs. Outdoor soffit and façade lighting with IP65/IP67/IP68 variants. Automotive and marine interior accents where compact width matters. Event and stage temporary installations that need quick mount and removal.

Lifespan and reliability

Rated at 50,000 hours under normal operating conditions. The LED junction temperature range is -20°C to 50°C — avoid enclosing the strip in sealed spaces without ventilation, as trapped heat shortens LED life. At 12 hours of daily use, that is roughly 11.5 years before brightness falls to acceptable end-of-life levels. The 3M adhesive may weaken over several years in high-heat environments; re-mount with additional fixing clips if the bond softens. The 50,000-hour rating assumes the strip is operated within its specified voltage and temperature range.

Why do buyers pick the FX-3528 over other SMD strips? Here is what we hear from customers:

Broad brightness range in one family. From the economical 30 LEDs/m model at 2.4 W/m to the high-output 240D at 19.2 W/m, the FX-3528 covers every common tier. You can mix variants on the same project and control them all from the same dimmer.

Seven colour options. Red, Green, Blue, Yellow for accents; Warm White, Cool White, and Commercial White for general illumination. CRI >80 is standard; CRI >90 is available for white variants. One product family covers both accent and functional lighting.

IP coverage for any environment. From dry indoor coves (IP20) to submersible pool lighting (IP68), the same form factor spans the full range. Just order the correct variant for your installation.

Easy to cut and install. The 25 mm cut length fits odd spaces precisely. The 3M adhesive backing sticks without tools. Installers tell us the 15 cm pre-attached cable saves time on standard runs.

Cost-effective for high-volume projects. The 3528 package is smaller and less expensive to manufacture than the 5050, making the FX-3528 practical when budget matters but reliable performance is still required.

Residential under-cabinet and shelf lighting. — The 30 and 60 LEDs/m models deliver economical, low-power illumination for kitchen under-cabinets, display shelves, and wardrobe lighting. The 120 LEDs/m model provides brighter task lighting. The 3M adhesive backing enables quick tool-free installation.

Cove and architectural accent lighting. — The 120 LEDs/m and 240 LEDs/m models produce bright, even illumination in ceiling coves, cornices, and recessed channels. The 120° beam angle ensures wide-angle coverage. The 24VDC-compatible models maintain brightness on longer runs up to 5 metres.

Commercial signage and display backlighting. — The 240 and 240D models deliver high brightness (1500 lm/m) suitable for light boxes, advertising signs, and retail display backlighting. The 240D double-row variant provides maximum output in a compact 15 mm width. Available in all seven colours for brand-matched signage.

Outdoor and landscape accent lighting. — The IP65, IP67, and IP68 variants extend use to covered outdoor installations including soffit uplighting, garden path marking, and façade accent lighting. The silicone-coated variants resist moisture for long-term outdoor performance.

Automotive and marine interior accents. — The narrow 8 mm to 15 mm PCB widths fit tight dashboard consoles and door panel channels. IP65 or higher is recommended for marine environments where moisture exposure is constant.

Event and stage temporary installations. — Quick adhesive mounting and straightforward dimmer wiring make the FX-3528 ideal for temporary event lighting that needs to be removed between shows. Colour choices let you match venue branding or seasonal themes.

CRI >90 is optional for white variants only. — Standard CRI is >80. CRI >90 is available as an upgrade for Warm White, Cool White, and Commercial White models. Saturated colours do not have a CRI rating.

Cuts at 25 mm intervals. — Always cut at the marked points on the PCB — cutting between marks breaks the circuit. Use a sharp blade and insulate exposed copper pads with heat-shrink tubing after cutting.

Standard roll length is 5 metres. — Custom lengths are available on request. The 3M adhesive backing is standard in yellow; red backing is an option. The 15 cm input cable is standard — custom lengths can be specified at order time.

Size your power supply with 20% headroom. — A 5 metre run of 120 LEDs/m draws 48 W — use a power supply rated for at least 60 W. Running a supply at its maximum causes overheating and reduces lifespan.

The 3528 package is smaller than the 5050. — The 3528 LED (3.5 mm × 2.8 mm) is smaller and less expensive than the 5050, but delivers lower maximum brightness per LED. For peak brightness applications, consider the FX-5050 series or a COB strip instead.
