Pulse Start vs. Probe Start Metal Halide LightingHigh-intensity discharge (HID) metal halide (MH) lamps are widely used in commercial lighting applications because they are about three times as efficient as incandescent lamps. For years, there has been one main...
Switching from a metal halide wall pack to an LED can seem daunting at first. The technologies are so different, that you may be worried about finding a solution that will give you the best results. With a wide range of LED wattages available, it can be hard to...
Some fixtures produce more light at the same input power than others. The energy used is measured in watts. The light output is measured in lumens. The wattage used is not directly related to the lumen output. Some fixtures have a higher efficacy. This means that the...
The Color Rendering Index (CRI) is a crucial concept in the lighting industry, indicating a light source’s ability to display colors in their truest forms accurately. It assesses how well a light source represents various shades, making it a significant factor...
If it is time to purchase new lighting such as LED high bay luminaires or LED wall packs, you likely have already seen how confusing it can be to navigate all of the style, wattage, and Kelvin options. This process is often made even more difficult given the array of...
When it comes to illuminating pathways, gardens, and pedestrian areas with precision and efficiency, LED bollard light fixtures stand out as a premier choice. The integration of advanced optics in these LED lamps enhances their functional appeal and demonstrates their...
Many first-time customers coming to Access Fixtures—even those new to the world of commercial lighting technology—know they want to upgrade to LED. The technology has become so efficient, cost-effective, versatile, and easy to maintain, it’s surpassing traditional...
As solid-state lighting technology advances and achieves traction in the lighting market, the way we measure light also changes. Scotopic conditions refer to low light levels where the human eye relies on rod cells to perceive surroundings. You may have encountered...
Knowing how to quickly calculate the annual light fixture electricity cost will help you decide which light fixture to select. For instance, an LED light fixture may use 50 watts of energy, while an equivalent metal halide version may use 112 watts of energy. Even if...

Footcandles (FC) are a unit of measurement used in lighting design to quantify the illuminance or the amount of light that falls onto a surface. Specifically, one footcandle is equivalent to one lumen per square foot. Footcandles play a crucial role in various...
Voltage refers to pressure from an electrical circuit’s power. Voltage is what pushes a current through a conducting loop, enabling it to illuminate a light. It is essential that managers of commercial facilities know the line voltage where fixtures are to be...
To achieve a specific color of light from a light source, it is essential to understand the Kelvin temperature – also known as the color temperature of a light source. A lamp’s color temperature signifies its warm, neutral, or cool color appearance. This...
Vandalism towards wall packs and property lighting is an ongoing issue. Varying “vandals” cause the lenses on wall packs to break such as people purposely damaging the fixture to cause the light to go out, sports balls hitting the lens, natural elements...
As LED wall packs gain market share, the most common designs for wall packs will most likely change (in fact, this is already happening). LED wall packs do not effectively use prismatic lenses like more traditional light sources. The optics of the fixture do not work...
