COB LED Strip Light 512 pcs CRI90 24VDC Dimmable 10mm Dotless Lighting

What Is the ILED-COB-512 COB LED Strip?

The ILED-COB-512 is a white COB (Chip-on-Board) LED strip featuring 512 LED positions per metre on a 10 mm flexible printed circuit. The COB manufacturing process mounts individual LED chips directly onto the substrate and coats them with a phosphor layer, eliminating the gaps between discrete SMD LEDs that cause visible dot patterns. The result is a continuous, uniform white light line with no hot spots — suitable for direct-view installations where the strip itself is part of the design.

Key Specifications

COB Technology vs Standard SMD Strips

Standard SMD LED strips mount individual LED packages (e.g. 2835 or 5050 chips) onto a flexible PCB at fixed intervals. Even with close spacing, the gaps between packages create visible brightness bands when viewed up close. The COB process eliminates these gaps by packaging multiple LED chips directly on the board and covering them with a uniform phosphor layer. This produces a continuous line of light with no visible LED dots — even at close mounting distances. The COB-512 is a superior replacement for traditional SMD tape lights and neon-style tube lighting.

Available IP Ratings

The COB-512 is offered in four IP variants: IP42 for dry indoor use, IP65 for splash-proof outdoor coverage, IP67 for temporary submersion, and IP68 for continuous underwater use. Select the rating that matches your installation environment at order time — the silicone coating and connector type differ between variants and cannot be changed after manufacture. Do not mix IP ratings on the same run.

Applications

The COB-512 is suited to environments where uniform white illumination and clean aesthetics matter — residential cove lighting, under-cabinet kitchen work surfaces, commercial retail display, hospitality interior accent, and architectural façade uplighting. The 10 mm narrow profile fits tight cove profiles and recessed channels. The 24VDC input provides stable performance over runs up to 5 metres without visible voltage drop. IP65/IP67/IP68 variants extend use to covered outdoor installations including soffit, fascia, and garden accent lighting.

Sibling Products

The COB-512 shares the same 10 mm dotless COB platform as the ILED-COB-480 series (13923, 13942) and the ILED-COB-608 DW (13921). Compared with the COB-480 (480 LEDs/m, 9-10 W/m), the COB-512 has a higher LED density (512 vs 480) and slightly higher output (1200 lm/m vs ~900-1000 lm/m). Compared with the COB-608 DW (608 LEDs/m, 20 W/m dual-channel), the COB-512 offers simpler single-channel control and lower power draw — suitable for shorter runs and lower-brightness applications where the 608 model would be over-specced.

The COB-512 delivers 512 COB LED positions per metre on a 10 mm PCB — higher density than the COB-480 (480 LEDs/m) — producing a brighter, more uniform white line with no visible LED dots. The COB manufacturing process eliminates the gaps between discrete SMD packages that cause banding and hot spots on standard strips.

With 1200 lm/m at 12 W/m (100 lm/W) and CRI >90, the COB-512 provides energy-efficient, high-quality white light suitable for colour-critical environments such as retail display, gallery lighting, and kitchen task areas. The 180° beam angle ensures even illumination across the target surface.

Four IP ratings (IP42, IP65, IP67, IP68) cover indoor and outdoor use. The 50,000-hour rated lifetime and 24VDC low-voltage input make it a safe, long-lasting solution for both residential and commercial projects. The 10 mm narrow profile fits tight cove profiles where wider strips cannot.

How does the COB-512 differ from the COB-480?
The COB-512 has 512 LEDs/m at 12 W/m delivering 1200 lm/m, while the COB-480 (13923/13942) has 480 LEDs/m at 9-10 W/m delivering approximately 900-1000 lm/m. Both share the same 10 mm width and dotless COB technology. The COB-512 offers slightly higher brightness and LED density at a moderate power increase — choose the COB-512 for brighter runs and the COB-480 for lower-power or shorter installations.

How does the COB-512 compare to the COB-608 DW?
The COB-608 DW (13921) has 608 LEDs/m, runs at 20 W/m, and features two independent white channels (3000K + 6000K) requiring a dual-channel controller. The COB-512 has 512 LEDs/m, runs at 12 W/m, and uses a single white channel. The COB-608 DW is brighter but draws more power and needs a more complex controller. Choose the COB-512 for simpler installations and lower-power applications.

How does the COB-512 differ from the COB-840 RGB?
The COB-840 RGB (13929) produces RGB colour (red, green, blue) for dynamic colour effects; the COB-512 produces only neutral white light (2700K-6000K). They share the same 10 mm COB platform but serve different purposes. If you need colour-changing effects, choose the RGB model. If you need uniform white illumination, choose the COB-512.

Which IP rating should I choose?
IP42 for dry indoor installations (ceiling coves, under-cabinet). IP65 for covered outdoor use (soffits, sheltered eaves). IP67 for outdoor areas exposed to rain. IP68 for wet environments or submersion. Do not mix IP ratings on the same run — each variant has a different silicone coating.

Can the COB-512 be cut to custom lengths?
Yes. The COB-512 cuts at 62.5 mm intervals — this is the cut length for this specific variant. Always cut at the marked PCB points; cutting between marks breaks the circuit. The COB-480 (13942) cuts at 50 mm; the COB-480 (13923) offers both 25 mm and 50 mm; the COB-840 RGB (13929) cuts at 25 mm.

Residential cove and ceiling lighting.
— The dotless 180° beam provides uniform white illumination in ceiling coves, cornices, and recessed channels with no visible LED points. The 10 mm narrow profile fits tight cove profiles and the flexible PCB follows curves. The 24VDC input minimises voltage drop on longer runs, maintaining colour consistency.

Kitchen under-cabinet and task lighting.
— High CRI (>90) ensures accurate colour rendition for food preparation and workspace visibility. The dotless output prevents distracting point sources on work surfaces. The IP42 variant is suitable for indoor kitchen use; IP65 is recommended for kitchen areas exposed to steam or splashes.

Retail display and merchandise lighting.
— The 1200 lm/m output and CRI >90 make this strip effective for illuminating product displays, shelf edges, and feature walls. The uniform white line draws attention to displayed items without creating glare or hot spots. Suitable for clothing, jewellery, and food retail environments.

Architectural accent and façade lighting.
— The IP65, IP67, and IP68 variants extend use to covered outdoor installations including soffit uplighting, fascia accent, and garden pathway lighting. The tunable neutral white range (2700K-6000K) allows matching exterior lighting to architectural intent — warm white for residential character, neutral white for modern commercial facades.

24VDC only. — Not compatible with 12VDC systems. Always pair with a 24VDC power supply rated for total current draw (approx. 0.5A/m at 12 W/m) with a 20% margin. Undersized power supplies cause dimming and shortened LED lifetime.

CRI >90 on all channels. — The COB-512’s single white channel meets CRI >90 across the 2700K-6000K range. This makes it suitable for colour-critical applications such as retail display, gallery lighting, and kitchen task areas where accurate colour rendering matters.

Cuts at 62.5 mm intervals. — This is the only cut length on the COB-512; always cut at marked PCB points. The COB-480 DW (13921) cuts at 50 mm; the COB-480 (13923) offers both 25 mm and 50 mm; the COB-840 RGB (13929) cuts at 25 mm. Never cut between marks — this breaks the circuit.

Standard roll length is 5 metres. — Custom lengths available on request. The 3M adhesive backing is standard in yellow; red backing is an option. The 15 cm input cable is standard — custom cable lengths can be specified at order time.
