LED strip SMD 3528 12V 4.8W/m blue 60LED/m IP20 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

A single-color mono LED strip emits blue light. It is a single-channel light source — all LEDs operate together, without independent color mixing. The mono LED strip family includes, among others, red, green, blue, violet, pink, amber, yellow, UV, and near-UV models.

The color of the emitted light depends on the spectral distribution of the LED radiation, characterized among other parameters by its dominant or peak wavelength. Red and amber belong to the long-wavelength region of the visible spectrum, yellow and green occupy its middle range, while blue and violet are located toward the short-wavelength, higher-frequency end. UV radiation lies outside the visible spectrum, whereas near-UV is located close to its boundary and may be perceived as deep violet while strongly exciting fluorescence in certain materials.

Red, green, and blue are the primary colors of the additive RGB color model. In multi-channel systems, mixing them makes it possible to produce secondary colors — for example, yellow from red and green, and magenta or pink from red and blue. This does not mean, however, that a single-color yellow, amber, or violet strip mixes RGB channels. In a mono strip, the specified color is produced directly by the LEDs used or by their specifically engineered spectral characteristics. Pink and magenta are non-spectral colors — they do not correspond to a single wavelength, but rather to a specific combination of spectral components. Spectral violet, on the other hand, can be produced directly in the short-wavelength region of visible light.

Perceived brightness depends not only on radiant power, but also on the sensitivity of human vision. Under photopic, or daylight, vision conditions, maximum sensitivity occurs near 555 nm. For this reason, yellow-green and green light may appear particularly intense at the same optical power. Under scotopic, or night-vision, conditions occurring at very low illumination levels, peak sensitivity shifts toward approximately 507 nm, in the blue-green region. Red and amber then become relatively less visible.

Blue light has a very distinctive appearance and is highly effective at attracting attention, particularly in large, simple shapes viewed from a greater distance. At low luminance, however, small blue elements may appear less sharp, slightly blurred, or surrounded by a visible halo. This results, among other factors, from the chromatic aberration of the human eye and reduced visual acuity in the short-wavelength region of the spectrum. For this reason, blue is not the best choice for small lettering, thin outlines, or complex symbols where maximum sharpness and detail legibility are critical. It performs very well, however, as a strong signaling and decorative accent.

For static operation, a mono LED strip does not require a controller — it only needs to be connected to a correctly selected power supply. Light intensity adjustment requires a compatible single-channel LED dimmer or controller, most commonly using PWM modulation. In the case of UV and near-UV strips, the model should be selected primarily according to its actual wavelength and intended application, because apparent brightness is not a reliable measure of radiant power.

LED strip - product overview

The strip operates at 12V and has a density of 60LED/m with an IP20 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.

Blue LED strip 300LED SMD 3528 — stable light for premium projects

Need a crisp blue accent that stays consistent? This blue LED strip 300LED SMD 3528 balances diode density and power draw. It works well in many indoor installations. The 3528 LEDs deliver a steady hue and a clean, modern look. Use it for shelves, alcoves, signage, and architectural highlights. For best results, mount it in an aluminum profile. The profile improves cooling and keeps the line of light tidy.

Why choose this blue LED strip 300LED SMD 3528

• 300 LEDs for an even, continuous glow.
• SMD 3528 technology for stable blue color.
• Universal use for accents, displays, and profiles.
• Easy installation with adhesive backing and cut points.

Applications for a blue LED strip for profiles

• Backlighting for furniture, shelves, and niches
• Architectural accents and soffits
• Advertising, exhibitions, and signage
• Ceiling lines and aluminum LED profiles

Power supply and safety

Choose a constant-voltage LED power supply matched to your total load. Add a 20–30% power reserve for reliability. Look for protections like OVP, OCP, SCP, and OTP. Models with active PFC can improve stability and operating culture. This approach supports premium, high-quality lighting results.

Voltage drop and power injection

Long runs may cause dimming at the end of the strip. Use power injection to keep brightness even. As a rule, feed power about every 5 m for 12V systems. For 24 V systems, feed about every 10 m. Use a star wiring layout when possible. Choose proper wire gauge for the current and length. Seal connections if moisture is present.

Installation and cutting

You can cut the strip only at marked cut points. Connect segments by soldering or quality connectors. Clean the surface before sticking the tape. An aluminum profile helps heat dissipation and extends lifespan. This keeps the blue effect sharp and consistent.

FAQ

Which power supply should I buy?
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 runs or when brightness must stay uniform. Feed every 5 m (12V) or 10 m (24 V).

Can I cut and reconnect the strip?
Yes, at the cut marks. Use correct soldering temperature and solid insulation.
