Our fixtures require low voltage (24VDC) and must be connected to an LED driver. If connected directly to line voltage (120–277VAC), the integral LEDs will be permanently damaged. As a result, the fixture may be completely unlit - or it may emit only a low level of light, flicker, or display uneven illumination.

If connected directly to line voltage, the integral LEDs will need to be replaced. Please email info@lukelampco.com for rope replacement details and pricing.

Using a voltmeter, measure the voltage where the rope is connected to power:

a. If you confirm 24VDC at this location, reconnect the rope with the polarity of the wires reversed (e.g. red-to-black and black-to-red vs. red-to-red and black-to-black). This will not damage the fixture, and may resolve the issue.

b. If no voltage is detected at this location, refer to Step 3 below (driver output voltage).

c. If less than 15VDC is detected at this location, refer to Step 4 below (controller compatibility and wiring).

d. If greater than 24VDC is detected at this location, the fixture may be connected to line voltage (120-277VAC). Please refer to Step 1 above for contact information and replacement details.

If you measure 24VDC output from the red and black wires at the driver (but not at the fixture), check every wire connection between the driver and the fixture until you find the broken connection.

If no voltage is detected at the driver output location, disconnect the low voltage wires connecting the driver to the fixture and measure again:

a. If you measure 24VDC output from the driver with the fixture disconnected, there may be too many fixtures connected to a single driver or there may be another issue with your wiring (such as a short circuit). Confirm the wattage of each fixture and inspect the wiring.

b. If no driver output voltage is detected even with the fixture disconnected, proceed to Step 4 (controller compatibility and wiring).

NOTE: The following steps should only be performed by a licensed electrician.

Disconnect the dimmer or control system. Then, connect the driver to line voltage (120-277VAC) without a switch:

a. If you measure 24VDC, there may be an issue with the wiring, compatibility, or settings on the dimmer or controller you are using. Please see our Driver Specification Guide for more information about dimmer compatibility.

b. If you do not measure 24VDC, please call (914) 294-2024 ext. 2 or email info@lukelampco.com so that we can send you a new driver.

All drivers generate heat during operation. If they do not have sufficient airflow, they may temporarily shut off as a safety measure to prevent overheating.

Please refer to our Driver Specification Guide for the installation requirements specific to your driver.

The combined wattage of all fixtures connected to a single driver must not exceed the driver’s rated wattage. If the load is higher than the driver’s rating, it may operate temporarily, but will shut off once the driver’s temperature limit is exceeded.

The LEDs inside each rope have a front and a back side. If your fixture contains multiple ropes, or if you have multiple fixtures, the LEDs may be facing different directions inside the rope.

To correct this, loosen any set screws holding the ropes in place and gently twist the rope until the brighter sides are facing the same direction.
