COB LED Strip Light 512 pcs CRI90 24VDC Dimmable 8mm Dotless Lighting

What Is the ILED-COB-512 8MM COB LED Strip?

The ILED-COB-512 8MM is a white COB (Chip-on-Board) LED strip featuring 512 LED positions per metre on an 8 mm flexible printed circuit — the narrowest width available in the ILED COB lineup. The COB manufacturing process mounts individual LED chips directly onto the substrate and coats them with a uniform 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

8 mm Width — Narrowest Profile in the COB Range

The COB-512 8MM features an 8 mm PCB width — 2 mm narrower than the COB-512 10MM (13918). This additional narrowness makes it suitable for installations where space is limited: ultra-narrow cove profiles, tight corner joints, minute recessed channels, and applications where even a 10 mm strip would be visually dominant. The 8 mm width does not compromise brightness or LED density — it still delivers 512 LEDs/m at 1200 lm/m. The trade-off is slightly reduced flexibility on tight-radius curves compared to the 10 mm variant, but for most straight-line and moderate-curve installations the difference is negligible.

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 8MM is a superior replacement for traditional SMD tape lights and neon-style tube lighting.

Available IP Ratings

The COB-512 8MM 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 8MM is suited to environments where a narrow profile and uniform white illumination are both required — tight cove lighting, narrow under-cabinet channels, slim architectural reveals, and compact retail display edges. The 8 mm width allows installation in spaces where a 10 mm or wider strip would be visually obtrusive or physically impossible to fit. The 24VDC input provides stable performance over runs up to 5 metres. IP65/IP67/IP68 variants extend use to covered outdoor installations including soffit, fascia, and garden accent lighting.

Sibling Products

The COB-512 8MM shares the same LED density (512 LEDs/m) and electrical specs as the COB-512 10MM (13918), differing only in PCB width — 8 mm versus 10 mm. Choose the 8MM version when the narrowest possible profile is required; choose the 10MM version when slightly more flexibility on curves is desired. Both are also siblings of the COB-480 series (13923, 13942), the COB-608 DW (13921), and the COB-840 RGB (13929), all sharing the same dotless COB platform.

The COB-512 8MM delivers 512 COB LED positions per metre on an 8 mm flexible PCB — the narrowest profile in the ILED COB lineup. The 8 mm width fits installations where a 10 mm or wider strip would be visually dominant or physically impossible, without sacrificing brightness or LED density.

With 1200 lm/m at 12 W/m (100 lm/W) and CRI >90, the COB-512 8MM 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. The dotless COB process eliminates visible LED dots for a clean, uniform white line.

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 8 mm narrow profile is the key differentiator against the 10 mm sibling — choose this model when every millimetre of width matters.

How does the COB-512 8MM differ from the COB-512 10MM?
The COB-512 8MM and COB-512 10MM share identical LED density (512 LEDs/m) and brightness (1200 lm/m) but differ in PCB width: 8 mm versus 10 mm. The 8MM version fits tighter cove profiles and narrow channels where the 10MM strip would be visually dominant. The 10MM version offers slightly more flexibility on tight-radius curves. Both are 24VDC, CRI >90, with IP42/IP65/IP67/IP68 options.
How does the COB-512 8MM compare to the COB-480 DW (13921)?
The COB-480 DW is a dual-white (2-channel) COB strip at 608 LEDs/m with 10 W + 10 W per metre. The COB-512 8MM is single-white at 512 LEDs/m and 12 W/m. The DW model allows warm-to-cool white mixing; the 8MM delivers fixed neutral white. Both share the same dotless COB technology and 24VDC input.
Can I cut this strip myself?
Yes. The COB-512 8MM cuts at 62.5 mm intervals — always cut at the marked copper pads. Use sharp scissors or a precision cutter. Do not cut between marks; this severs the circuit and ruins that section. Each cut produces a usable segment with its own 15 cm cable or solder points.
What power supply do I need?
Each metre draws 12 W at 24VDC (0.5 A). For a 5 metre run, size the power supply at 60 W minimum with a 20% margin — 72 W recommended. Use a 24VDC DC-DC adapter or switching power supply rated for the total load. Do not exceed 5 metres per feed point to avoid voltage drop.
Is this suitable for outdoor use?
The IP42 version is indoor only. IP65, IP67, and IP68 variants are available for outdoor use — select the rating that matches your exposure at order time. The silicone coating and connector type differ between IP variants and cannot be retrofitted. Do not mix IP ratings on the same run.
What is the difference between COB and SMD strips?
COB (Chip-on-Board) mounts individual LED chips directly onto the PCB with a uniform phosphor layer, producing a continuous line of light with no visible dots. SMD (Surface-Mounted Device) strips mount individual LED packages at fixed intervals, creating visible brightness bands between LEDs. COB strips are preferred for direct-view installations where the strip itself is visible.

Ultra-narrow cove and ceiling lighting.
— The 8 mm profile is the narrowest option in the COB range, fitting into cove channels and recessed profiles where even a 10 mm strip would be visually dominant. The dotless 180° beam provides uniform white illumination with no visible LED points. The 24VDC input maintains colour consistency on runs up to 5 metres.

Narrow under-cabinet and task lighting.
— High CRI (>90) ensures accurate colour rendition for food preparation and workspace visibility. The 8 mm width fits behind slim cabinet edges and narrow trim where wider strips cannot. The dotless output prevents distracting point sources on work surfaces. IP42 for indoor kitchens; IP65 for steam-prone areas.

Compact retail display and merchandise lighting.
— The 1200 lm/m output and CRI >90 make this strip effective for illuminating product displays and shelf edges in tight display cases. The narrow 8 mm profile allows installation in display niches where a wider strip would be visually intrusive. Uniform white line draws attention without creating glare or hot spots.

Architectural accent in constrained spaces.
— The IP65, IP67, and IP68 variants extend use to sheltered outdoor installations including narrow soffit uplighting, tight fascia channels, and garden pathway lighting. The neutral white range (2700K–6000K) allows matching exterior lighting to architectural intent — warm white for residential character, neutral white for modern commercial facades.

8 mm width — narrowest in the COB range. — Uses an 8 mm flexible PCB, 2 mm narrower than the COB-512 10MM (13918). Fits ultra-tight cove profiles and narrow channels where wider strips cannot. Same brightness and LED density as the 10MM version (512 LEDs/m, 1200 lm/m). Choose this when width is the limiting factor.

24VDC only. — Not compatible with 12VDC. Always pair with a 24VDC power supply rated for total current draw (approx. 0.5A/m at 12 W/m) with a 20% margin.

CRI >90 on all channels. — Single white channel meets CRI >90 across 2700K–6000K. Suitable for colour-critical applications such as retail display, gallery lighting, and kitchen task areas.

Cuts at 62.5 mm intervals. — 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.
