LED strip SMD 5050 12V 7.2W/m red 30LED/m IP20 5m

LED Strip - Construction

The strip uses SMD technology with LEDs in a 5050 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 red 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.

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.

Red LED strip 150LED SMD 5050 – subtle accents, premium stability

Need a clean, vivid red glow without excessive power use? This red LED strip 150LED SMD 5050 uses a lower LED density for gentle accents. It still delivers a stable, consistent red color thanks to 5050 SMD technology. It is a practical choice for profiles, furniture lighting, and signage. Use it where you want clear red highlights and reliable performance.

Why choose this red LED strip 150LED SMD 5050

• 150 LEDs for softer, more controlled light lines
• SMD 5050 for stable color and dependable output
• Lower power draw than denser strips in many setups
• Easy installation in aluminum profiles for better cooling

How SMD 5050 works in simple terms

SMD 5050 LEDs are larger diodes designed to emit strong, even light. In this version, the spacing is wider. That helps create subtle accents and reduces total power demand. The red tone stays consistent along the strip when you power it correctly.

LED strip for aluminum profiles and accent lighting

This red LED strip 150LED SMD 5050 fits well in aluminum profiles. Profiles improve heat dissipation and make the installation look premium. Use it for shelves, niches, ceilings, under-cabinet accents, and decorative lines. It also works great for advertising and display lighting.

Where it works best

• Furniture, shelves, and recess lighting
• Architectural accents and soffits
• Signage, displays, and promotional installations
• Ceilings and linear profile lighting

Power supply selection (constant voltage)

Choose a constant-voltage power supply matched to your strip’s total wattage. Add a 20–30% safety margin for stable work. Look for protections like OVP, OCP, SCP, and OTP. Models with active PFC can improve operating stability.

Power injection to keep brightness even

Long runs can cause voltage drop. Use power injection to keep the red tone uniform. For 12V systems, feed power about every 5 m. For 24V systems, feed about every 10 m. Use a star wiring layout and proper cable gauge.

Cutting, joining, and installation

You can cut the strip only at marked cut points. Connect using soldering or quality connectors. Clean the surface before mounting. For the best premium finish, install inside an aluminum profile and protect connections from moisture.

FAQ

Which power supply should I buy?
Calculate total wattage of all sections and add 20–30% headroom. Choose a unit with OVP/OCP/SCP/OTP protections.

When do I need power injection?
Use it for longer runs or when you notice dimming at the end. Feed every 5 m (12V) or 10 m (24V).

Can I cut and reconnect the strip?
Yes, at the cut marks. Use proper soldering temperature and grounded tools.
