BERIXDEEP COB LED Strip 20m with 480 LEDs/m, 24V, 3000K – Warm White, Dimmable

What it is

The BERIXDEEP COB LED Strip is a long, dense LED tape designed for interior lighting projects. It uses COB (Chip on Board) LEDs with a beam spread that aims to minimise visible dots and deliver a continuous light strip. The specified density is 480 LEDs per metre across a 20 metre reel, with a 24V power requirement and a warm 3000K colour temperature. It is dimmable, rated at about 9W per metre, and claims a higher Colour Rendering Index (CRI) around 92, which can help colours appear more natural in living spaces or display areas. The kit does not include a power supply, so you’ll need to source a suitable 24V driver separately.

How it performs

On paper, the COB approach can offer smoother illumination with better thermal management than some SMD-based tapes. The high LED density is intended to balance continuous, even light output with efficient power use. The 180° beam design aims to reduce dark spots and create more uniform lighting along coves, under cabinets or backlighting in rooms. The warm white colour is typically suited to living rooms, bedrooms and hospitality spaces where a relaxed ambience is preferred. The 92 CRI suggests decent colour fidelity for everyday scenes and decor. Real-world results will depend on installation, heat, and the chosen driver.

Key features

• 20 m roll with 480 LEDs per metre for a dense, dotless appearance
• 24V operation and dimmable performance
• 3000K warm white colour temperature, suited for living spaces
• CRI around 92 for faithful colour rendering
• 8 mm wide strip, designed for flexible installation on various surfaces
• High thermal efficiency with copper PCB and robust adhesion

Technical details

• Power: approximately 9 W per metre
• Colour temperature: 3000K (warm white)
• Beam angle: 180° (to minimise dark spots across the strip)
• LED density: 480 LEDs/m on 20 m length
• LED technology: COB (Chip on Board)
• Input: 24V DC (power supply not included, match to your setup)
• Characteristic: dimmable, copper double-sided PCB for improved heat management

What stands out

For those installing lighting where continuous, smooth light is valued, the COB approach and high LED density can reduce the typical dotted appearance seen with lower-density tapes. The respectable CRI score and warm tone can help replicate natural ambience in living areas and display setups. It’s also aimed at DIY projects, where flexibility and ease of cutting or shaping the strip can simplify installation in tight spaces like cupboards or behind furniture.

Practical usage tips

• Plan your run and driver capacity ahead: for 20 m at 9 W/m, ensure the chosen 24V supply can handle total demand with headroom for dimming.
• If you’re mounting behind translucent surfaces or under cabinets, ensure a clean, flat surface and remove the protective film only after you’re ready to mount to avoid trapping dust.
• Consider heat buildup: COB strips rely on effective heat dissipation, avoid enclosing in tight, non-ventilated pockets.
• Use compatible dimming hardware to maintain smooth dimming behaviour across the entire length.
• A test section before committing long runs can help confirm brightness and colour consistency across the reel.

Who it’s for

This strip suits DIY home projects, living room accents, cabinet lighting, wardrobes, mirrors and display cabinets where a warm, softly diffused light is desired. It’s particularly relevant if you value higher CRI for more natural colours in decor and you’re prepared to source a 24V driver separately.

Who it isn’t ideal for

If you need an extremely bright display or a cool white tone, or you want a ready-to-run kit with included driver, this option may not be the best fit. It also requires acquiring a power supply and potentially a mounting surface that supports heat dissipation, so it’s not plug-and-play out of the box.

When it makes sense to buy

• You’re planning a long, continuous lighting run on a 24V system and want a warm white ambience.
• You prioritise high CRI and even illumination with a compact, dot-free appearance.
• You’re comfortable sourcing a separate power supply and ensuring correct wiring for dimming.

When to reconsider

• If you need a quick setup with included power supply and controller.
• If your space demands a significantly brighter or cooler light output.
• If you’re unsure about heat management and surface compatibility for long runs.

What to check before purchasing

• Ensure your 24V driver can handle the total wattage (9 W per metre × 20 m = roughly 180 W, plan for dimming headroom).
• Confirm surface suitability and mounting method, the strip uses strong adhesive plus a durable PCB but proper surface prep helps longevity.
• Verify dimmer compatibility to avoid flicker or inconsistent brightness.
• Check the included protective film removal timing to avoid adhesion issues.

Comparison at a glance

If you’ve used lower-density SMD strips before, you might notice a more uniform, less spotted light with this COB approach. It represents a mid-to-high density option that trades off the need for a power supply in a fixed voltage system with a requirement to source a driver separately. In contexts where you want a soft, warm glow and faithful colour, this design can be preferable to harsher cool whites or more speckled outputs.

Final verdict

Should you buy it? It makes sense if you’re planning a longer, continuous warm-white installation and are prepared to handle a separate driver. It isn’t the simplest plug-and-play solution, but for ambience-focused interiors and display lighting, its combination of high density, dimmability, and high CRI offers a tangible upgrade over more basic tapes. Consider alternatives if you need an included power supply or a brighter, cooler option, or if you want a simple, all-in-one kit.

FAQ

• Does it come with a power supply? No, a DC24V driver is required separately.
• What’s the expected brightness? About 90 lm/w wattage efficiency is advertised, actual brightness depends on length, dimming level and installation.
• Is it suitable for kitchens? Yes, the warm white tone and high CRI can be pleasant for living areas and kitchens where a cosy ambience is desired.
• Can I cut the strip? The description implies standard COB tape practices, but you should follow manufacturer guidance for cutting and connection points.
