How to Choose a COB LED Strip: Color, Width and Power

Start with the result you need

A shelf, a cove and a work surface can need different results. Record the illuminated area, viewing distance, mounting space and whether the strip will be visible directly or in a reflection. Test a sample in its intended position and keep the exact SKU with your notes.

Choose color before the controller

Fixed white provides one specified color temperature. Compare samples beside the materials and existing lighting. A lower Kelvin value describes a warmer white; it does not say how bright the strip is. Two strips with the same nominal CCT can still look different.

Tunable white adjusts white light within the model's range using compatible controls. RGB combines color channels; it does not establish the quality of white light. For a dedicated white channel, compare the exact RGBW or RGB+CCT model and its controller requirements.

Start with the COB strip category. The 3000K M-C-480 variant, M-C-640-CCT and M-C-840-RGB illustrate different choices. They do not necessarily share controllers or connectors.

Measure the complete connection

Record PCB width, contact-pad layout, coating and connector clearance. An 8mm connector is not automatically suitable for every 8mm strip. Confirm the exact COB board and contact arrangement. Compare the connector's outside dimensions with the channel opening, not just the bare PCB.

COB describes emitter construction. It does not guarantee lumen output, uniform appearance in every shallow channel or outdoor suitability. Test with the intended lens and mounting depth. The channel fit guide explains which dimensions and included parts to check.

Keep length and power units together

For a hypothetical strip rated 10W/m, 3m represents a nominal 30W load. This is a planning example, not a specification for the linked products. A 5m reel is a package length, not permission to connect further reels end to end. Check the exact model's maximum run and supply instructions.

Do not confuse lm/W, an efficacy measure, with lm/m or total lumens. Continue with the driver and dimming guide to check the supply and controls.

Confirm the assembly and order contents

Check the strip, driver, connectors and enclosure instructions for the actual location. A coating or aluminum channel alone does not establish rain, cleaning or immersion suitability. See the IP rating guide when comparing markings.

Record the strip SKU, length, supply, controller, channel, lens and connections. Confirm selling units and included accessories. Send the model list and mounting details for a comparison; branch availability and suitability are confirmed for the selected items.
