COB LED strips use Chip-on-Board technology to place hundreds of tiny diodes in a continuous line, producing a smooth, dotless beam of light. Unlike traditional SMD strips, COB tape eliminates the visible "dots" you see through diffusers, making it ideal for cove lighting, under-cabinet accents, and any application where a seamless glow is desired. These flexible strips can be cut to length and installed in tight or curved spaces.
Types and Options
COB tape comes in several formats to suit different projects. Width is a key differentiator: narrow 3mm and 5mm tapes fit slim channels and tight corners, while 8mm versions offer higher chip density and brightness. Many options ship on 5-metre reels with chip counts such as 504 or 320 chips per metre. Higher-end variants feature CRI90+ for accurate, true-to-life colour rendering. Color temperatures are commonly available in 3000K (warm), 4000K (neutral), and 5000K (cool), and some products arrive pre-wired for faster connection.
Where to Use Them
In residential settings, COB strips shine in kitchens, under cabinets, along staircases, behind headboards, and in crown moulding for ambient cove lighting. In commercial and architectural projects, they create clean linear accents in retail displays, hospitality lobbies, signage, and display cases where a uniform line of light enhances the overall design.
How to Choose
Start with voltage — common options run on 24V, which allows longer runs with less voltage drop. Match your color temperature to the mood: warmer tones for cozy living spaces, cooler tones for task areas. Check the IP rating; an IP20 tape suits dry indoor locations, while damp areas need higher protection. Consider CRI if accurate colour matters, and confirm the strip width fits your aluminum channel. Finally, calculate your total wattage to select an appropriately sized driver.
FAQ
Can I cut COB LED strips? Yes, COB tape can be cut at the marked intervals along the strip to fit your installation.
Do COB strips need an aluminum channel? A channel is recommended for heat dissipation, protection, and a finished look, though it is not always required.
Are COB strips brighter than SMD? They offer a more uniform, dotless output; brightness depends on chip density and wattage per metre.
