How does the Power & CCT selection feature work in our products? Adjustable CCT is achieved by incorporating a mix of 3000K and 5000K LED chips inside the light. To arrive at the specific CCT selected by the lighting professional, the light output of the different color LED chips is adjusted to 100%, 50%, or 0%. Fixtures with adjustable power capabilities have a switch or a dial that controls the strength of the current sent to all the LED chips, which affects their overall brightness. Together, these features allow precise control over the light output of the fixture, to achieve the exact level and color of light the customer requires for their facility.

Choosing Power & CCT selectable fixtures has significant benefits for both distributors and lighting professionals. For a distributor, it can be challenging to predict which power and CCT options will be in demand at any given time. It is possible that a light with a specific power and CCT configuration doesn’t sell well, and just ends up taking up shelf space. Stocking Power & CCT selectable fixtures ensures that one product can fulfill a wide range of project requirements, which means one Power & CCT selectable fixture can replace several fixed power and CCT fixtures on the shelf. This allows the distributor to keep track of fewer products, saving time, money, and labor. Stocking Power & CCT selectable lights also simplifies the work of the sales team, minimizing the range of product configurations they have to be familiar with.

For lighting professionals, selecting LED lighting for a project is a precise art, requiring that many different aspects of a setting be taken into consideration. However, even with the most careful planning, it can be difficult to predict how a specific light will work in an environment. It is much easier to choose the precise lighting for a space when the CCT and wattage can be tweaked on site, and much simpler to adjust the light output if the customer isn’t satisfied with the lighting after the completion of the project. Additionally, for extensive projects requiring different light outputs for different areas in a facility, it is much easier to keep track of one Power & CCT selectable fixture and adjust the CCT and wattage based on the light’s location, as opposed to having to remember the exact installation location for a number of fixtures with different fixed power and CCT.

We currently offer several products with adjustable Power & CCT controls and will be bringing more on board this year.

GKOLED Series GKOPL Power & CCT Tunable LED Panels feature a convenient switch on the fixture housing that allows the contractor to adjust the wattage and CCT during installation. Available in popular sizes of 2×2 and 2×4 and certified DLC Premium, these fixtures are ideal for commercial environments with recessed or suspended grid ceilings. Fixed wattage and CCT Emergency-Ready models are also available.

The new GKOLED Series GKOWPG14 Non-Cutoff Wall Pack features Power & CCT Adjustment Controls that are standard on every fixture and are safely located behind a threaded knockout in the housing. This premium quality wall pack is available with a glass or polycarbonate lens and is equipped with a quick mount bracket that eliminated the need to open the fixture during installation. Optional photocells, motion sensors, and emergency battery backups are available for this fixture.

Finally, our Series GKOHB05 Circular High Bay features a Wattage Adjustment Dial that allows the contractor to lower the wattage of the light from 340W to 300W or from 250W to 200W. This powerful, efficient high bay is ideal for illuminating large commercial spaces with tall ceilings, and is available with an optional integrated, center-mounted motion sensor.

The LED driver provides a LED fixture with the correct power supply needed to ensure optimal performance. Many premature LED failures are the result of a failed driver, so choosing a LED fixture with a high-quality driver goes a long way to ensure reliable operation.

A good indication that a LED fixture contains a quality LED driver is a DLC Standard or DLC Premium designation from the Design Lights Consortium, one of the major organizations that help set the standards for high quality in LED lighting. As part of the DLC certification process, the LED driver in a product undergoes rigorous testing to ensure it meets strict performance requirements. Almost all GKOLED products are DLC Standard or DLC Premium listed, which means that our LED drivers meet or exceed the high standards for quality designated by the Design Lights Consortium.

Another good way to determine the quality of a LED driver is to check its Power Factor (PF). Rated on a scale from 0 to 1, the Power Factor of a driver indicates its efficiency, with a PF of 1 providing perfect efficiency and lower numbers indicating a large amount of wasted electricity. For LED fixtures, a PF of 0.9 (or 90%) is considered excellent. If the LED driver has a low Power Factor, it can indicate that the manufacturer has tried to cut costs on a fixture by using a low quality driver.

Power Factor is an important consideration for a successful commercial LED lighting project. Most utility companies charge by the wattage used by the LED light and not by the actual amount of electricity delivered, however, the extra electricity wasted by inefficient LED drivers with a low Power Factor still has to be generated and provided by the power plant. Because of this, some utility companies will apply a penalty charge for low Power Factor energy use, which will eat into the savings the commercial customer hopes to obtain by switching to LED lighting in the first place.

Additionally, because the Power Factor of a LED driver affects the amount of current drawn by the driver, it determines the number of fixtures that can be accommodated by an electrical setup. The lower the Power Factor, the fewer the amount of fixtures that can be installed. This makes low Power Factor LED drivers problematic for bigger commercial LED lighting projects requiring a large number of LED lights.

All GKOLED LED fixtures feature a driver with a Power Factor of 90% or greater. We use high end proprietary LED drivers or source from respectable manufacturers such as Inventronics to ensure maximum efficiency and reliability in our LED products.
