Dimmer Compatibility

Armacost Dimming LED Drivers are compatible with both forward phase 

(leading edge, triac, incandescent) and reverse phase (electronic low-

voltage, ELV, and trailing edge) AC dimmers, including higher end lighting 

controls, such as Lutron GRAFIK Eye

®

 systems. They are also compatible 

with low-voltage PWM dimmers and RGB color controllers.
Although virtually all dimmers will work with Armacost Dimmable LED 

Drivers, Armacost Lighting recommends dimmers that can be programmed 

or have an adjustment dial to set the low end dimming range, such as 

Lutron

®

 C•L and Leviton IllumaTech

®

 Universal Dimmers.

IMPORTANT: Armacost drivers do not need a minimum wattage load for 

proper operation, but some AC dimmers may have this requirement. Check 

the specifi cations of your dimmer to confi rm that your lighting exceeds 

this value, or choose a dimmer with little or no load requirement.

MOUNTING OPTIONS

To surface mount the LED tape light under a set of cabinets in one 

continuous run, you may need to drill a 1/2 in. hole through any 

cabinet side lip that may be present. Install LED tape light through 

the hole and surface mount as a continuous run.

For maximum light output and to focus light on the work surface, 

mount the tape light 1-2 inches behind the front cabinet lip. This 

mounting position works best with dull or matte fi nished countertops.

The LED tape has 

a wide beam angle

Mount on inside of cabinet 

lip to reduce refl ections

To eliminate bright spots from highly refl ective countertops, mount 

the tape light on the inside back of the cabinet lip frame facing 

towards your backsplash. Because of the wide beam angle of the tape 

light, this mounting position will still provide ample lighting. 

When mounting under a cabinet or a shelf with no lip to hide the LED 

tape light strip, create a visual barrier using a piece of quarter round 

molding or any angle trim to hide the LEDs. 

Creating above cabinet uplighting

Most cabinet tops have uneven surfaces. To create indirect uplighting 

over cabinets, simply mount the LED tape on any rigid strip (e.g., 

thin lattice or corner guard molding) and place on top of cabinets. 

Angle the strip position to achieve the desired illumination. 

For a seamless glow and to avoid bright light spots, move the LED 

tape light strip further from adjacent walls.

Mount LEDs 

farther from 

the wall to avoid 

bright spots

CEILING

CARE AND CLEANING

To clean the light, use a clean dry or slightly damp cloth.

Do not use cleaners with chemicals, solvents or harsh abrasives 

as damage to the light strip may occur.

TROUBLESHOOTING

The LED strip will not light.

The power supply does not have power. Make sure the plug is fully inserted 

into a live 120-volt outlet. Check connections and circuit breaker.

The power supply output cable is not properly secured. Make sure that the 

DC output cable is wired securely to the output of the power supply.

The polarity is incorrect. Check that the orientation of the input and 

output match the markings on the case.

Only part of the LED strip lights.

A connection point is faulty. Check for secure connections at the point 

that is not lit. Confi rm that polarity is the same between the lit and 

unlit segments.

The fuse blows or a circuit breaker trips when the light is turned on.

A wire is exposed. Discontinue use of the lamp. Unplug the unit from 

the wall. Contact a qualifi ed electrician.
