And these aren’t just marginal improvements. In a study conducted by Philips, improved lighting for facilities in the metal industry led to a 52% reduction in accidents when increasing light levels from ~30 to 185 foot candles.

Lighting plays a critical role in commercial and industrial businesses. It impacts safety, productivity, mood, ambiance, product merchandising, and even profitability. This is why achieving the right amount of light for the activities happening in the space is so important.

With photometric software, design teams can determine the best optics to effectively distribute the light produced, allowing the fixture to both cover more ground and consume energy in the most efficient in the most way (reducing the amount of energy that needs to be consumed to achieve the light levels needed). Industrial facilities with dated technologies like HPS or CFL have the opportunity to both reduce their fixture counts (often by as much as 50%+) while 10x’ing the life expectancy!

At PEC, we refer to this as “try before you buy.” With the benefit of highly accurate and dependable measurements, photometric design plans allow businesses that are considering a lighting investment to confidently determine ROI and project payback periods.

Interpreting light starts by understanding its attributes: quality, color, direction, and luminosity. Of these factors, light direction distinguishes the overall theme of an image, as shadows and highlights cast onto the subject based on the light’s direction can either emphasize or reduce imperfections.

Remember that as long as the reflector is pointing at your subjects, it’s going to be extremely bright and hard to look at. Give your subjects good breaks in between shots otherwise they’re probably going to walk away very damaged eyes and a new tan.

But how do we achieve the “right” amount of light? Underlit areas, as one can imagine, creates a long list of problems ranging from safety hazards to poor customer experiences. The same can be said with overlit areas, which can lead to glares, excessive energy use, poor lighting consistency, and harsh lighting for customers.

‘Cast’ is defined by the way light and shadows are hitting a surface. Seasons and physical location are the primary determinants of what type of light direction you will be able to use. As long as the sun is giving us a direction of light, it’s very easy to work with; the problem occurs when the sun is directly overhead, casting dark shadows and strong highlights. Therefore, the worse the light direction the more modification we generally need.

One common concern for shooting indoors involves mixed lighting, or blending natural and ambient light, as ambient light sources usually cast a different light temperature than daylight (3200K vs. 5500K for natural light). We normally try to avoid mixed lighting. However, it is okay to mix natural and ambient light if the ambient light doesn’t affect the main or natural light that is falling on the subject. In fact, mixed lighting can be used to benefit images in some scenarios when it separates the subjects from the background.

Beyond safety, optimal lighting in industrial facilities has also led to big gains in productivity. The same study by Philips tied better light levels to improvements in task performance, garnering an 8% increase in productivity, as well as seeing reduced product waste that stemmed from poor visibility.

Consistency can be a big issue particularly for industrial facilities like manufacturing plants or distribution centers that have long, ongoing operating hours (i.g. 24/5 – 24/7). This is because burned out bulbs can be expensive and taxing to replace when factoring in the the costs with halting production, sourcing the correct equipment, and getting over the top of machines to replace the bulb. As a result, it’s common for these types of facilities to carry on operations with the burned out bulbs — creating “hot spots” over time that subtly diminishes lighting quality and visibility.

Photometric design plans are key to maximizing the energy efficiency of your lighting system. Lighting designers can first determine the optimal IES recommended light levels for a given space, then incorporate fixtures and lumen packages that achieve this light level using the least amount of energy.

The secret to finding that perfect balance is done through photometrics, which is the science behind how lighting behaves in a particular environment. In this piece, we’ll cover some of the key benefits of photometrics, and why all C&I properties should consider photometric design plans for their future lighting investments.

You can use objects around you, like dirt, grass, or white walls to reflect light. Search for surfaces that reflect more neutral tones to serve as natural reflective surfaces that you can use as fill.

As a result of a brighter and evenly distributed light levels, your workforce is better positioned to reduce mistakes, be more alert, quickly detect hazards, and avoid accidents.

After this process, the design plan options, ROI calculations, and cash flow reports will be presented to you so you can confidently determine if a retrofit is the right investment for your business.

A different study conducted by the CDC also demonstrated that improved lighting in mining environments led to huge improvements to worker safety, including:

As mentioned before, maintenance demands can be especially heavy for industrial facilities with long operating hours. One major advantage of photometric plans is that it allows design teams to achieve consistent, optimized light levels in the most efficient way — commonly leading to both a reduction in fixture count, as well as increases in fixture life expectancies.

Generally, when we’re shooting with direct lighting, we want to wait for the ‘Golden Hours’ (sunrise & sunset) during the day when the sun is at it’s lowest point on the horizon, creating a giant softbox that’s reflecting onto your subject. However, if mid-day sun is all you have, here are three different types of modifications you can try with a reflector:

Design plans that don’t incorporate photometrics are susceptible to either overlighting spaces, or integrating optics that don’t achieve the light in the most efficient manner, which leads to excessive energy consumption and greenhouse gas emissions.

Light direction still exists even when the sun is blocked by trees or clouds. While placing your subjects in the shade does help you avoid harsh direct lighting, there is still a direction that favors the brightest light source. Keep in mind that light from the sky acts as a fill, reflecting off surfaces to add light into the shadows.

Just as outdoor lighting presents a number of challenges for capturing picture perfect images, indoor lighting also demands adaptability and creativity from photographers. For instance, there are basic scenarios that photographers will regularly find themselves in while shooting indoors, such as near windows, inside hotel rooms, or under overhangs, that call for a mastery of using directional light.

Simply turn and study the direction of light wherever you are and to see how it falls onto your hand. Although you may look like a crazy person for a couple of seconds, it is a useful trick to avoid shifting your subjects or letting them bake in the sun for too long.

Harsh mid-day lighting causes the strongest cast of shadows, but that doesn’t necessarily mean it is not flattering with the help of modification. Facing your subjects directly into the sun fills the face with light and creates strong shadows around the eyes but no dimension on the contours of the face.

Lighting designers that leverage photometrics are able to quantifiably measure how much light is optimal for a particular activity happening in a facility. The Illuminating Engineering Society (or IES) publishes standards that determine the optimal amount of light for a particular environment or activity. These light level standards, which are measured in units of foot candles, can be incorporated into photometric software that allows lighting designers to learn which fixtures and optics will best achieve that recommended amount of light.

In addition to achieving the correct light levels, photometrics also enable lighting designers to achieve an optimal lighting consistency throughout the facility. Shadows and big fluctuations in light levels from space to space, known as lighting “hot spots”, creates visibility challenges as the eyes have to adjust.
