Q: How do I determine the number of lights that I can have on a transformer?
A: When you buy a Kerr Lighting Kit, the transformer included in the package is sized to accommodate the included lights. Should you decide to add lights to the Kit, or when planning a project with individual lights, the wattage of the transformer must exceed the total wattage of the lights on the line. For example, if your project includes 10 lights on a line, each with a 7 watt bulb, the transformer must have at least 70 watts of power (10 lights x 7 watts each).
Q: Can I use a stronger bulb in my light than the one that it came with?
A: Yes you can, provided the total wattage of the lights on the line does not exceed the total wattage of the
transformer.
Q: Can I use my Kerr lights with an existing low voltage system?
A: Absolutely. As with all low voltage systems, make sure the transformer can accommodate the total wattage of the lights connected to it.
Q: Can I drive over my Paver lights?
A: Paver Lights are made from high-strength polymer plastics and are engineered to withstand the weight and pressure of light vehicular (cars and light trucks) loads.
Q: The lights at the end of the line seem to be dimmer than those at the front. What’s happening?
A: Lights closest to the transformer will receive more power than those further down the line. If a cable run is too long or if too many lights are being powered by a single transformer, noticeable voltage drop may occur. Voltage drop causes the lights farthest from the transformer to become dim. Voltage drop can be minimized by: using a heavier gauge cable (Kerr Lighting recommends a maximum power cable length of 100 feet on 16/2 cable and 300 feet for 12/2 cable), using a transformer with greater wattage, using multiple transformers, shortening cable lengths, or reducing the total number of fixtures on a run.
Q: Can I retrofit Paver Lights into an existing hardscape installation?
A: If you have concrete or clay brick pavers that are not set in mortar, it’s easy to install Paver Lights. Most times it’s simply a matter picking up the border pavers, installing the power cable underneath, and then reinstating the pavers and lights.
Q: Where can I find replacement bulbs for my Kerr lights?
A: Low voltage bulbs are readily available at most retail home centers, hardware stores and other retail locations.
Q: Do you make a solar-powered Paver Light?
A: We do not make a solar powered light. Solar Lights need lots of direct sunlight to power them, and most areas of the country do not receive enough consistent sun to keep them burning bright and illuminated long enough. The lights themselves also need to be in direct sunlight to charge the batteries. Since they require low voltage power, Kerr lights require little electricity and can be placed anywhere, even in completely shaded areas.
Q: I’ve read a lot about LED lights. How do Kerr Lights compare?
A: LED lights are more expensive than low voltage lights. They also emit a relatively low amount of light at a relatively small angle range, while low voltage light bulbs illuminate in all directions and give out much more brightness of light. LED’s are also very sensitive to extreme temperatures (both hot and cold) and may not operate properly in these conditions.
Q: How will my Paver lights perform in snow and ice?
A: When installing Paver lights in areas where there may be snow, make sure that the fixtures do not protrude above the surface so they don’t get caught by the edge of a shovel or plow. The lights themselves give off enough heat to melt any snow or ice that may accumulate.
Q: Can I run a plate compactor over my Paver lights?
A: When using Kerr Paver Lights in a new installation, light lenses can be scratched by plate compactors if not protected. Please cover the lens with cardboard or a similar protective material to ensure that it does not become damaged during compaction.
Q: How should I handle my Paver lights when cleaning and sealing my pavement?
A: Do not apply Paver cleaners or sealers to the light lens to prevent discoloration.
Q: Does my power supply cable have to be installed in a hard conduit?
A: No. The low voltage cable can be buried directly in soil, sand, or stone.
Q: What are the white “L” shaped clips that came with my 4 x 8 Paver Lights?
A: The clips are inserted into the holes in the bottom of the Paver Light so that the pavers on either side will hold it in place.
Q: Can I install Paver Lights in a concrete patio, walkway, or driveway?
A: Yes you can, but we recommend using the 4 x 8 brick shape only. You’ll have to notch the concrete to accommodate the fixture. Make sure there is free-draining stone under the light or drill holes in any concrete that may remain.
