Preparing Installation (continued)

Con guration options
□ LED tape strips can be installed in series (strips connected or wired end-to-end) or in parallel (multiple legs of LED strips
or series of strips wired directly to a single power supply).
□ LED tape lighting power requirements are based on several factors, including your con guration (Straight Run, Center
Feed/Loop Back or Array), voltage drop, and the length limitations of the LED tape light.
Straight Run
Only one end of the LED strip is powered.
Multiple strips can be connected in a
series for a continuous run. LEDs farther
away from the power supply may appear
dimmer due to voltage drop, especially if
longer wires are used in between to
connect strips.

Choosing a power supply
Refer to the charts below for the recommended maximum lengths of LED tape lighting based on your con guration and choose a power
□
supply rated greater than your needs - you cannot overpower LED tape lighting. The LED power requirements shown below are based
on 100% full power brightness levels and do not represent every possible installation scenario.
NOTE: Do not use a standard 120V AC wall dimmer with your power supply unless the power supply clearly
states that it is dimmable with AC dimmers.
□ Due to voltage drop, longer lengths of LED tape will use fewer watts per foot than shorter lengths. The total watts used in an array
layout depend on the wattage requirement of each leg and overall voltage drop within your connection wires. A leg can be a single
LED strip or series of strips connected end-to-end. Various legs are wired in paralled directly to the power supply.
Calculate the wattage for each leg by multiplying watts per foot by the length of LED lighting in the leg. Include only the lengths of
LED tape in your calculation, not the connecting wires. Add each leg's wattage requirement together to determine the total watts
needed to power your array and select a power supply that exceeds the total watts needed.

TYPICAL CONFIGURATIONS
Center Feed / Loop Back
Either power two equal legs of tape lighting from the
center or loop back and power both ends of the LED
tape. These con gurations will produce more
consistent brightness and color over the length of the
strip. A loop back is excellent for room perimeter tray
ceiling or cove lighting.

*Due to voltage drop, exceeding 24-foot lengths will cause LEDs farthest from the power supply to appear dimmer. It is okay
to use a higher wattage power supply, however, it will not reduce the impact of voltage drop.

Array
An array uses two or more legs of
various lengths wired to a power supply
in a parallel connection. You will need to
calculate total wattage used in an array
to guard against overloading the power
supply.
