Extra Long COB LED Strip 48V, COB Strip 12V 24V 48V

Best applications for 48V single-color COB strips

48V COB strips are ideal for long linear runs like commercial cove lighting, retail fascias, and architectural outlines where minimal voltage drop and fewer feed points are desired.

How to calculate maximum run length for 12V vs 24V vs 48V single-color COB strips before voltage drop occurs

Higher supply voltage lets you run longer lengths — 12V runs are usually limited to a few metres per feed, 24V can double that, and 48V often supports still longer continuous runs — but exact limits depend on watts per metre and acceptable voltage drop, so calculate per-case using strip current and conductor resistance.

Recommended drivers for 48V COB strips

Use a regulated constant-voltage 48V LED driver sized at or above the strip’s total wattage (with ~20% headroom) and featuring protection (short-circuit, thermal) suitable for continuous operation.

How to prevent voltage drop on long 48V COB runs

Use 48V to reduce current, run heavier-gauge supply cables, and inject power at multiple points or run parallel feeds from the driver to maintain even brightness.

Cutting and joining single-color COB strips safely at 12V, 24V and 48V

Always cut only at the manufacturer-marked cut points, use correct-voltage-rated connectors or soldered joints, and fully insulate/seal connections to prevent shorts and preserve the strip’s electrical rating.

How to calculate power supply amperage for a 5 m, 24 W/m single-color COB strip at different voltages

Total power = 24 W/m × 5 m = 120 W; amperage = watts ÷ voltage, so expect ~10 A at 12V, ~5 A at 24V, and ~2.5 A at 48V, then add ~20% headroom when choosing the PSU.

Does higher voltage like 48V reduce wiring thickness needs for commercial COB projects?

Higher voltage lowers current for the same power, which often lets you use thinner wiring or longer cable runs for the same voltage drop target, but mechanical and local-code requirements still dictate minimum conductor sizes.

Can I mix 12V and 24V single-color COB strips in the same aluminum channel setup?

Physically you can mount different-voltage strips in the same channel, but they must be powered and controlled separately — never connect different voltages to the same feed or driver.

What dimmers or controllers work with 48V single-color COB strips for tunable white?

Use constant-voltage 48V PWM dimmers or purpose-built 48V tunable-white controllers that match the strip’s voltage and total current rating.

Why do 48V COB strips maintain brighter output over distance compared to 12V versions?

Because the higher voltage results in lower current for the same power, reduced I²R losses mean less voltage drop and therefore more consistent brightness along longer runs.

Are IP65 single-color COB strips at 24V suitable for waterproof gardening in humid climates?

IP65 protects against splashes and rain but not full immersion, so IP65/67 strips can work for humid outdoor environments if connections are sealed and mounting prevents standing water; use higher IP ratings for harsher conditions.

How to calculate power supply size for 12V, 24V and 48V COB strips

Sum each strip’s watts (W/m × length), then choose a power supply for each voltage rated at least 20% higher than the total watts to allow safe continuous operation.

Best wiring method to minimize voltage drop on long 48V runs

Run multiple parallel feeds from the driver, use appropriately sized conductors, and minimize run length of the highest-current segments to keep voltage drop within acceptable limits.

How to choose between constant-voltage and constant-current COB strips

Choose constant-voltage (12/24/48V) strips for simple, flexible installations with standard controllers, and constant-current solutions when precise current regulation per LED is required for very high-power or specialty lighting.

Recommended LED drivers for high-wattage 24V COB strips

Select a high-quality 24V constant-voltage driver rated above the combined wattage with protections (overload, short-circuit, thermal) and good efficiency; for very long or segmented runs consider multiple smaller drivers to reduce voltage drop.

How to inject power along long COB strips for even brightness

Inject power from the supply at intervals (e.g., both ends and midpoints) or run parallel trunk cables that feed the strip at multiple positions to equalize voltage and color consistency.
