Frequently Asked Questions

Common questions from importers, wholesalers, and project contractors about this product.

Which driver is required for this DC12/24V, 7W/M strip?

The strip is listed for DC12/24V at 7W/M. Fix one voltage version on the order and use a regulated constant-voltage driver that matches it. Size each branch from its connected meters and follow the driver manufacturer's loading and temperature-derating instructions.

Does the listed 5M/10M supply length equal the maximum powered run?

No. 5M/10M is the available supply or reel length. Maximum powered length depends on the exact model, voltage, watts per meter, feed direction, cable resistance, connectors and the accepted voltage drop. Confirm the feed-point plan separately.

How should CRI 90 and color consistency be approved for this model?

The sheet lists 3000K / 4000K / 6500K / BLUE and CRI 90. State the required CCT and color tolerance, then approve a powered sample in the intended profile and diffuser. For repeat orders, agree how batch matching will be checked.

Will standard connectors and profiles fit the 3mm PCB?

Do not assume so. Narrow PCB models need a connector, soldering method and profile with enough usable width and cable clearance. Approve the joint, strain relief and bend near the connection before volume production.

What should the approval sample prove for this 7W/M selected construction?

Record model COB-3MM-400LED (RA90) and check DC12/24V input and 7W/M power, 3000K / 4000K / 6500K / BLUE, 5M/10M, Confirm for selected construction, color matching. Add the production-intent driver or rectifier, connector, profile and packaging. The signed specification and retained sample should control later batch inspection.

How is the exact DC12/24V selected construction approved before production?

The quotation, specification sheet and approved sample should identify the same model, electrical rating, construction, reel length and packaging. Record measurable acceptance limits before production rather than relying on a family-level description.
