LED strip SMD 3528 Slim 12V 4.8W/m warm white 60LED/m IP33 5m

LED Strip - Construction

The strip uses SMD technology with LEDs in a 3528 package. The underside has factory-applied double-sided adhesive tape to aid installation on a suitably prepared surface. The Slim variant uses a narrow PCB.

Control of LED strip

The strip can be powered directly from a suitable 12V power supply. An optional PWM controller enables brightness adjustment.

Important information

The stated power is a rated or theoretical value based on the parameters of the components used. Actual power consumption may be lower due to component tolerances, voltage drop and operating conditions.

Power and installation

The strip does not require an additional power-injection point when its length does not exceed 5m. Above this length, consider starting the next separately powered run, supplying the run at its far end, or adding another power point after the indicated length.

The 5m value is based on the electrical properties of the strip PCB. It indicates the length at which supply-voltage drop should not cause a noticeable reduction in LED brightness along the length of strip. Above this length, a brightness difference may become visible. If it remains acceptable to the end customer, the final power-feed arrangement is the responsibility of the installation designer or user.

Light emitted by LED strip

The presented white LED strip is a single-channel light source with a color temperature of 3000K. All LEDs emit the same color and are controlled simultaneously, providing uniform and stable illumination.

In most white LEDs, light is produced through a phosphor-conversion process. A blue semiconductor chip emits short-wavelength radiation, part of which is converted by a phosphor layer into longer-wavelength visible light. The combination of the original blue light and the radiation emitted by the phosphor creates a broad spectrum perceived by the human eye as white light.

The composition and proportions of the phosphor materials make it possible to control the color temperature, tint, luminous efficacy, and color rendering quality with high precision. In high-quality LEDs, a properly engineered spectrum can faithfully reproduce the natural appearance of illuminated objects and colors, bringing the character of the emitted light close to daylight or traditional incandescent lighting. Particularly important factors include a high color rendering index, the correct balance of spectral components, and strict LED binning for color consistency. As a result, in typical applications, the light produced by a high-quality LED strip can be visually very difficult to distinguish from that of natural or traditional light sources.

During operation, an LED ages gradually rather than failing suddenly through a conventional “burnout.” The most commonly observed process is a slow reduction in luminous flux over time. High operating temperatures can accelerate degradation of the semiconductor structure, phosphor, package materials, and electrical connections. Over time, the phosphor may lose some of its conversion efficiency, while optical materials may become discolored, leading to a slight shift in color temperature or chromaticity coordinates.

In high-quality LED strips, this aging process is slow, uniform, and predictable. Proper thermal management, stable power supply, and installation in a suitable aluminum profile reduce the operating temperature, helping to preserve the original brightness and light color for many years.

For static operation, the strip does not require a controller — a correctly selected power supply is sufficient. Brightness adjustment requires a compatible single-channel LED dimmer or controller, most commonly using PWM modulation.

LED strip - product overview

The strip operates at 12V and has a density of 60LED/m with an IP33 ingress-protection rating.

Sales unit of led strip

The sales unit includes a factory-prepared reel of LED strip with a length of 5m.

LED strip - power supply selection

The strip requires a power supply with an output voltage of 12V. Guidance: select a power supply with an optimum 30% power reserve above the LED strip demand.

Power supply and voltage drop tips

Choose a constant-voltage power supply matched to total wattage. Add a 20–30% power reserve for safe operation. Look for protections like OVP, OCP, SCP, and OTP. Active PFC improves stability and work culture.

For long runs, use power injection to avoid dimming. Feed 12V strips about every 5 m. Feed 24V strips about every 10 m. Use a star wiring layout and proper cable gauge. Protect outdoor connections from moisture.

Installation in profiles

Mount with the adhesive backing on a clean surface. An aluminum profile improves cooling and durability. Connect using soldering or quality connectors. Cut only at the marked cutting points.

FAQ

Which power supply should I choose?
Sum the wattage of all sections and add 20–30% reserve. Pick a unit with OVP/OCP/SCP/OTP protections.

When do I need power injection?
Use it for longer lengths or visible brightness drop. Add power every 5 m (12V) or 10 m (24V).

Can I cut and reconnect the strip?
Yes, at the cutting marks. Soldering gives the most reliable connection.
