LED strip SMD 3528 12V 4.8W/m 4000K 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.

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 4000K. 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.

LED strip 300 LEDs 4000K IP20 — clean, neutral light

Choose a balanced solution for everyday interior projects. The LED strip 300 LEDs 4000K IP20 combines solid LED density with sensible power use. It delivers a comfortable neutral white 4000K tone.

Why choose an LED strip 300 LEDs 4000K IP20?

• Neutral white 4000K for natural, non-tiring lighting.
• IP20 for indoor, dry rooms and enclosed profiles.
• Cuttable at marked points for precise lengths.
• Great for aluminum profiles and clean architectural lines.
• Premium build focused on stable, reliable operation.

Applications for LED strip 300 LEDs 4000K IP20

• cabinet, shelf, and niche lighting
• accent lines in ceilings and walls
• shop displays, signage, and showcases
• under-cabinet task lighting in kitchens

Neutral white LED strip 4000K — power supply and voltage drops

Use a constant-voltage LED power supply matched to total wattage. Add a 20–30% safety margin for long life and stable brightness. Look for protections like OVP, OCP, SCP, and OTP. Models with active PFC can improve efficiency and work culture.

For longer runs, voltage drop may reduce brightness at the end. Apply power injection to keep light even. As a rule, feed every 5 m for 12V or every 10 m for 24V. Use a star wiring layout and proper cable gauge.

LED strip IP20 installation tips

Mount on a clean, degreased surface. The adhesive backing helps, but an aluminum profile improves heat dissipation and durability. Connect using soldering or quality connectors. Keep joints protected and strain-free for best results.

FAQ

Which power supply should I choose?
Calculate total strip power and add 20–30% headroom. Pick a unit with OVP/OCP/SCP/OTP protections.

When do I need power injection?
When runs are long or brightness must stay perfectly uniform. Extra feeds stabilize the output.

Can I cut and reconnect the strip?
Yes, cut only at marked points. Soldering gives the most reliable connection.
