Size the right driver for your run. Applies the 80% safety rule and recommends matching ENKORA power supplies.
Inputs
The recommendation builds in 20% headroom per the standard 80% loading rule for LED drivers.
Minimum recommended PSU
60W24V
Length
20.0 ft
Watts / ft
1.5 W
Total load
30.0 W
20.0 ft × 1.5 W/ft = 30.0 W total load
30.0 W ÷ 0.80 = 37.5 W minimum → rounded up to 60 W
Voltage-drop caution
At 20 ft this exceeds the published single-feed run for this strip (9.8 ft). The far end will dim and shift cooler. Solve by powering from both ends, injecting power mid-run, splitting into shorter segments, or moving to 24V if you're on 12V.
Estimate only. Final electrical specification — including breaker, conductor sizing and code compliance — should be reviewed by a licensed electrician.
