Cutting, connecting and wiring

RibbonFlex Pro is designed for custom lighting installations. Basic wiring skills

such as stripping and splicing wire connections are required.

Always maintain polarity when

connecting LED tape lighting and low

voltage power wires.

Be sure to connect positive wires to

positive (+ to +), and negative wires

to negative (– to –). Polarity is easily

identiﬁ ed with + and – marking on

LED tape as shown.

Cut with scissors

This tape light model can be cut every 3 LEDs, or about every 2”. Only cut

tape light in the center of the copper pad locations, “A,” as shown below. If

you cut at a soldered position, “B,” also shown, you may need to remove the

solder from the tape connection joint in order for an LED Snap Connector to

work properly. Solder joint positions are located every 19.7 inches (½ meter).

LED Snap Connectors make easy, secure solderless connections

Wire Lead Snap Connectors

Wire Lead Snap Connectors are used for going around corners or, when cut in

half, to create two power leads (“jumper” cables) for linking and extending

power wires to LED tape lighting in other areas.

IMPORTANT: Always use the + / – indicators printed on the tape light to

maintain polarity (+ to +, – to –).

To make longer

“jumper” cables

Cut in half to

create two wire lead

connectors that can

be spliced to longer

wires in order to get

power to LED tape

strips in other areas.

To get power from one LED strip to another, you can extend wire leads as shown

below. 22-18 AWG wire should be sufﬁ cient for extending wire leads up to 10 feet.

Shorter and/or thicker wires will mean less voltage drop and higher brightness. For

an online voltage drop calculator, visit armacostlighting.com/installation.

Wire splice connections: Maintain polarity when extending cables and be

sure all splice connections are secure. Splicing options include crimp

connectors, wire nuts, terminal blocks and soldering wires. Be sure to use

wire connectors that are sized for the wire gauge you are using.

Splice Snap Connectors

Splice Snap Connectors are for joining two strips to create a continuous run

of LED lighting.

ﬂ ip the tape and use the opposite

end for proper alignment.

How to use Snap Connectors

■

Pry open lid on the side you wish to connect an LED strip to.

■

Peel back about ¼ inch of the 3M adhesive backing on the bottom of the strip.

Conﬁ guration options

RibbonFlex Pro offers endless connection options to ﬁ t virtually any

installation imaginable. 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).

TYPICAL CONFIGURATIONS

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.

POWER

SUPPLY

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 conﬁ 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.

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.

Choosing a power supply

LED tape lighting power requirements are based on several factors, including

your conﬁ guration (chart above), voltage drop, and the length limitations of the

LED tape lighting. Refer to the charts below for the recommended maximum

lengths of LED tape lighting based on your conﬁ 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.

Maximum length of LED tape based on conﬁ guration type and power supply

Power Supply Straight Run Center Feed / Loop Back

6 Watt 3.3 ft (1.0m) Not recommended

15 Watt 10.5 ft (3.2m) 9.0 ft (2.75m)

30 Watt 24.0 ft (7.3m)* 20.0 ft (6.0m)

60 Watt 24.0 ft (7.3m)* 48.0 ft (14.6m)

*Length limitations indicated here are based on the inherent limitations of the LED tape due to voltage

drop in a straight run. Exceeding these lengths will cause LEDs farthest from the power supply to

appear dimmer. A higher wattage power supply will not reduce the impact of voltage drop. For more

consistent brightness consider a center feed or loop back conﬁ guration.

Array power supply calculation

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 parallel 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

the appropriate power supply.

Length of leg (LED tape light only) 1 to 5 feet 6 to 10 feet 11 to 15 feet

Watts used per foot 1.8 watts/ft 1.6 watts/ft 1.4 watts/ft

Calculate each leg’s wattage requirement separately, then add together for the total

watts needed for your array. Select a power supply that exceeds the total watts needed.
