How to Determine Correct COB LED Strip Specifications

While standardized component dimensions like strip widths and lengths pose fewer barriers, each installation environment and lighting purpose requires strategic evaluation choosing COB strips with technical aspects like power, brightness, color temperature, and optics optimally aligned with goals.

Prime Technical Factors

Voltage – 12 or 24 Volt DC working voltage dictated by supporting driver/transformer electrical output.

Wattage Rating – Impacts maximum permissible strip length serviced before overloading.

Lumens – Brightness specification set by room use cases & mounting height.

CRI Rating – Color Rendering Index quantifying light color quality and accuracy.

Beam Angle – Preferred spot or flood orientation shaping output spread.

Reviewing intended visibility and room needs against COB specifications jointly determines ideal selections. Consider adding secondary optics for further manipulation.

Critical Wiring Considerations for COB LED Projects

The specialized electrical requirements powering high density COB LED make planning infrastructure capabilities supporting deployed lengths crucially important before installations.

Electrical Load Calculations

Tabulate total wattages of planned strip sections and specify a sufficient wattage AC to DC driver avoiding potential overheating or failures from underpowered circuits.

Wire Gauge Ratings

Size conductor wires between COB lights and drivers correctly sustaining expected amperages to distances without voltage drops dimming output. Generally 12-10 AWG suits most small spaces.

Electrical Polarity

COB strips only activate when properly aligned positive and negative cable polarity matches markings. So trace wiring carefully without reversing.

Maximum Run Lengths

Compare COB strip cut points against circuit load capacities as lengths increase because exceeding maximum runs risks dangerous overheating and shorts without built-in protection.

While extra capacity poses no functional faults, planning electrical loads for COB elements at the core better guarantees smooth operation.

LED Strip Light Mounting Considerations

Properly mounting COB LED strips during planning stages makes installations easier while optimizing lighting positioning for uniform visibility and heat management.

Material Choices – Select mounting surfaces like aluminum sheets that dissipate heat, avoiding flammable materials contacting hot strips.

Adhesive Options – Use heavy duty self-adhesive, channel extrusions, or mounting clips based on surface types.

Visibility Goals – Mount strips centrally when spotlighting stages, or conceal above sight lines for indirect cove lighting.

Accessibility – Ensure ability to reach strips for maintenance avoiding permanent construction barriers inhibiting serviceability.

Once preliminary mounting decisions localize strips benefiting spaces, focus shifts to connecting provisioned electrical components granting operational life.

Wiring Step-by-Step Guide: Connecting COB LED Strips
