Collection: Single Color LED Strip Lights

What Are Single Color LED Strip Lights?

Single color LED strip lights produce one fixed light output across the entire strip length — no controller, no color-mixing circuit, no mode switching. Each strip is wired to a single constant-voltage driver and can be dimmed with a compatible PWM dimmer when brightness control is needed.

The category covers two main output groups: white LED strip lights in a range of color temperatures, and fixed-color LED strips in red, blue, green, amber, pink, purple and other saturated hues. Both use the same two-wire constant-voltage connection and are compatible with standard 12V or 24V LED drivers and dimmers.

White LED Strip Lights

White LED light strips are available in color temperatures from 2200K ultra-warm to 6500K daylight. The right CCT depends on the application:

• 2200K–2700K warm white — soft, amber-tinted light for bedrooms, living rooms, restaurants, hotels and hospitality interiors where a relaxed, comfortable atmosphere is the goal.
• 3000K–3500K natural white — balanced, neutral illumination suited to kitchens, bathrooms, retail displays and general residential spaces.
• 4000K–5000K cool white / bright white — clean, high-contrast light for offices, workspaces, garages, task lighting and commercial environments.
• 5000K–6500K daylight white — crisp, blue-shifted output used in workshops, photography, inspection lighting and display cases that want a bright, cool-white appearance. Note that CCT describes how the white light looks, not how accurately it renders color — that is determined by CRI, not color temperature.

Warm white and soft white LED strip lights are the most common choice for under-cabinet and accent lighting. Cool and bright white LED light strips are frequently specified for retail shelving, display cases and task lighting where higher CCT improves visual clarity.

For projects that require adjustable white light between two color temperatures, see Tunable White LED Strip Lights.

Fixed-Color LED Strip Lights

Red, blue, green, amber, pink, purple and ice blue LED strip lights are used where a specific, saturated hue is required without a color controller. Because the strip outputs only one color, it connects directly to a two-wire constant-voltage driver and can be dimmed with a standard single-color PWM dimmer.

Common applications for fixed-color LED strips include:

• Red LED strip lights — photography darkrooms, horticulture and plant grow lighting, vehicle and marine courtesy lighting, themed bars and entertainment spaces, and emergency exit identification.
• Blue LED strip lights — aquarium and tank lighting, pool and spa perimeter lighting, entertainment and gaming room accents, ceiling and cove details in hospitality interiors, and UV-adjacent decorative applications.
• Green, amber, pink and purple — retail signage, themed architectural lighting, stage and event production, food display lighting where specific color rendition affects product appearance, and decorative commercial interiors.

How to Choose a Single Color LED Strip

Color or CCT

Match the color temperature or hue to the space, merchandise or brand environment. Warm CCTs read as comfortable and relaxed; cool CCTs read as clean, bright and precise. For color-sensitive environments — food, beauty, artwork, apparel — prioritize high CRI alongside the correct CCT.

Brightness (Lumens per Meter, Not LED Count)

Compare luminous output in lumens per meter or per foot. LED count and chip model number alone do not determine brightness. Two strips with the same chip and density may differ significantly in lumen output and efficiency depending on driver current and bin selection. Review the listed lm/m figure alongside wattage and efficacy.

CRI (Color Rendering Index)

For retail merchandise, food display, beauty, artwork and hospitality spaces, choose strips rated CRI 90 or higher. CRI 80 is suitable for general utility lighting where color accuracy is not critical. Note that the headline CRI Ra figure averages eight low-saturation samples and includes no saturated red — where red rendition matters (meat, produce, wood tones, cosmetics, skin), ask for the R9 value or the TM-30 Rf/Rg figures as well.

Voltage: 12V or 24V

12V strips suit short runs, cabinet lighting, vehicle and marine applications and any system already wired for 12V DC. 24V strips draw roughly half the current at the same wattage: voltage drop scales with current (V = I × R) so the drop along the run is halved, while copper heating scales with the square of current (P = I²R) and falls to about a quarter. That extends the usable run length before visible dimming occurs, making 24V the standard choice for whole-room, commercial and long architectural runs. See the individual product page for maximum recommended run length.

Strip Width and Channel Compatibility

Widths range from 2.6mm ultra-narrow to 20mm wide. Confirm the PCB width fits the aluminum channel, sign groove or mounting surface before ordering. Slim profiles of 4–6mm fit micro-channels; standard 8–10mm strips are compatible with the widest range of extrusion profiles.

IP Rating

IP20 non-waterproof strips are suitable for dry indoor locations. IP65 or IP67 rated strips are required for damp areas such as bathrooms, kitchen splashback zones, outdoor soffits and any location exposed to moisture or condensation. For fully outdoor installations, check the specific product page for rated ingress protection.

LED Chip Type

Single color LED tape is available in SMD 2835, SMD 2025, SMD 1515, SMD 5050, SMD 3528 and other packages. The chip number describes the physical package dimensions — not the total output or quality. Evaluate strips by their published lm/m, W/m, CRI and density together. For a smooth, continuous appearance without visible individual LED dots, consider COB LED Strip Lights.

Single Color LED Strip Specialty Configurations

Beyond standard single-row strips, the catalog includes several specialized constructions for specific applications:

Single-LED Cuttable LED Strip Lights

These strips have a cut point between every individual LED, allowing trimming to the exact millimeter. Standard strips typically cut every 3, 6 or more LEDs. Single-LED cuttable designs are particularly useful for short cabinet runs, display cases and any application where standard cut intervals leave excess strip that cannot be concealed.

Ultra-Narrow LED Strip Lights

PCB widths of 2.6mm, 3mm, 4mm and 5mm for installations where a standard 8–10mm board will not fit. Compatible with micro-channel extrusions, slim sign letters, furniture edge details and display frame profiles.

High-Density LED Strip Lights

280–360 LEDs per meter for uniform, hotspot-free illumination in museum display, high-end retail, hospitality back-bar and architectural cove applications where standard-density strips show visible spacing between LEDs.

Bendable LED Strip Lights

Flexible PCB construction that bends horizontally around curves, corners and irregular surfaces without requiring connectors or kinking the board. Suited to shaped coves, curved signage and contoured architectural features.

Dual-Row LED Strip Lights

Two parallel rows of LEDs on a 10mm PCB, delivering approximately double the lumen output of a single-row strip in the same footprint. Used when maximum brightness is required without switching to a wider channel.

Installation and Dimming

Cut strips only at the marked cut points. The cut interval varies by model — single-LED cuttable strips cut between every LED; standard strips cut every 3, 6 or more LEDs as marked on the PCB.

Mount on a clean, flat surface. Aluminum LED channel profiles provide a finished appearance, physical protection and passive heat dissipation that extends operating life, particularly for high-density and high-output strips. Use the adhesive backing for temporary positioning; secure with clips or channel mounting for permanent installations.

Match the power supply output voltage to the strip voltage (12V or 24V). Do not mix voltages. Size the driver for the total connected wattage with at least 20% reserve capacity. For long runs, add additional feed points at regular intervals to maintain consistent brightness.

Dimmable single color LED strips require a PWM dimmer rated for the strip voltage and total wattage. Never wire a low-voltage strip directly to a mains phase-cut dimmer — the wall dimmer belongs on the AC side of the driver. Phase-cut (TRIAC) dimming is possible in this category, but only through a driver explicitly specified as TRIAC-dimmable.

Applications

Single color LED strip lights are used across residential, commercial and specialty applications including:

• Under-cabinet and under-counter lighting in kitchens, workspaces and retail
• Wardrobe, shelf and furniture accent lighting
• Cove lighting, toe-kick details, stair accents and architectural perimeter lighting
• Display cases, retail fixtures, jewellery showcases and museum vitrines
• Back-bar and hospitality interior lighting
• Signage illumination, channel letters and illuminated display frames
• Office and commercial task and ambient lighting
• Vehicle, marine and RV interior and courtesy lighting
• Aquarium, horticulture and specialty lighting using fixed-color red or blue strips

Contractors and trade buyers should verify maximum run length, cut interval, wire gauge, driver capacity and the safety certifications listed on each product page (UL Listed, CE, RoHS, UKCA, PSE and ErP).

Frequently Asked Questions

What is the difference between single color and tunable white LED strips?

Single color LED strip lights output one fixed CCT or color. The output cannot be adjusted between warm and cool white without replacing the strip. Tunable white (dual-white) LED strips contain two sets of LEDs — typically warm white and cool white — wired to a two-channel driver, allowing the color temperature to be adjusted between the two endpoints. If adjustable white light is a requirement, see Tunable White LED Strip Lights.

Which white color temperature should I choose?

2200K–2700K for warm, relaxed ambient light in bedrooms, living rooms, restaurants and hospitality. 3000K–3500K for balanced everyday illumination in kitchens, bathrooms and retail. 4000K–5000K for clean, high-contrast task lighting in offices, garages and commercial spaces. 5000K–6500K for crisp daylight output in workshops, photography and display applications. Check the listed CCT and product images — screen calibration affects how CCT appears on a monitor.

Should I use 12V or 24V single color LED strip lights?

12V is practical for short runs (typically under 5m from a single feed point), cabinet lighting, vehicle and marine systems. 24V draws half the current at the same wattage, which holds brightness more consistently over longer runs and is generally the better choice for whole-room, commercial and architectural linear lighting. Both voltages are available across most strip types; check the product page for the maximum recommended run length at each voltage.

Can single color LED strip lights be dimmed?

Most constant-voltage single color strips are compatible with PWM dimming when used with a suitable single-color PWM dimmer. Verify that the dimmer is rated for the correct voltage (12V or 24V), the total connected wattage, and the PWM frequency supported by the strip. A mains wall dimmer must never be wired directly between the driver and the strip — it belongs on the AC side. If you want to control the strip from a standard wall dimmer, use a driver explicitly rated as TRIAC-dimmable or 0-10V dimmable, matched to the dimmer type.

How far can I run a single color LED strip from one power supply?

Maximum run length before visible voltage drop depends on the strip wattage per meter, PCB copper weight, and driver output voltage. As a general guide, a standard 5W/m strip can run approximately 5m from a 12V supply and 10m from a 24V supply from a single feed point before dimming at the far end becomes noticeable. High-density and high-output strips have lower maximum run lengths due to higher wattage per meter. Check the individual product page for the specified maximum run length, and add injection points for longer runs.

What is the difference between SMD 2835, SMD 2025 and SMD 1515 chips?

The number describes the physical package size in tenths of a millimeter: SMD 2835 is 2.8 × 3.5mm, SMD 2025 is 2.0 × 2.5mm, and SMD 1515 is 1.5 × 1.5mm. Smaller packages allow higher LED density on a narrow PCB, which is why ultra-narrow and high-density strips often use SMD 2025 or SMD 1515 chips. Output, efficiency and color quality depend on the specific LED bin used, not the package size alone.
