Practical advice on commercial lighting from LED retrofits to lighting design.

Dimming LEDs can be tricky for a variety of reasons, and it can sometimes be difficult to pinpoint the source of the particular issue you're facing, like flickering. In this post, we'll zero in on one particular issue: a lack of load resistance.

Conventional (TRIAC) dimmer switches –– the ones designed to work with incandescent and halogen light bulbs –– require a certain amount of "holding current," or wattage in non-electrical-engineer terms, in order to work properly. When paired with an incandescent, the bulb draws enough voltage for the dimmer to work with and reduce. The control cuts the voltage, sending less to the lamp, or bulb, resulting in reduced light output (dimmed lighting).

Linear fluorescent lighting has for decades been the workhorse light source for so many applications, thanks to its long life ratings and relatively efficient use of energy. But the emergence of linear LED technology over the last decade or so has really changed the landscape, making buying decisions for linear applications more complex.

We get questions all the time about linear lighting. Is it risky to invest in LED lighting products? Are more fluorescent phaseouts ahead? What linear lighting products does Regency suggest?

Summer is in full swing and I'm glad, because that means baseball is in full swing. And I love baseball.

But the game of baseball is a lot like a lighting project. And I don't love lighting projects.

What gives?

Well, I should back up here. I work for a lighting company. So saying I don't love lighting projects isn't the most rah-rah thing to say. 

Lighting is one of those things that can be easily taken for granted. It’s sort of like cell phone service or drinking water –– it’s not something most people pay attention to unless it’s off.

Just like cellular networks and purified drinking water, details matter in lighting. Ensuring a cell signal isn’t spotty or that the total dissolved soluble content of water is palatable is a science. And it’s pretty easy to mess up.

With lighting, mistakes rarely go unnoticed. And even the less-noticed ones can have a trickle-down effect on sales.

The job of the lighting designer is to help you avoid such oversights, ensuring your lighting is sharp, consistent, and right for your brand.

In that spirit, here are the most common mistakes our team sees in retail lighting design:

Lighting manufacturers speak different dialects of the same language: part numbers. The point of our part number series is to help you to better understand what all of those characters on your light bulb mean, so you can accurately and easily order replacement products.

Understanding part numbers is especially helpful when manufacturers begin to phase out and discontinue certain products, causing you to have to buy replacement products from another manufacturer. That's especially useful if you have compact fluorescent (CFL) bulbs, with so many manufacturers beginning to phase them out of production.

What products should you retrofit to LED first? 

Our lighting experts get that question all the time. Fortunately, there’s a pretty simple answer.

If you have any applications in your building that still have incandescent or halogen lighting, start there first. Why?

The retrofit from incandescent or halogen to LED gives you the biggest energy savings and almost always the fastest return on investment. We all want to make our money back quickly on investments, right? If you’re using linear or compact fluorescent lighting anywhere in your building, your lighting is already fairly efficient, especially when compared with incandescent or halogen lighting. 

It takes a lot of energy to keep an apartment building running. Unlike a commercial office or most retail stores, apartment buildings are open to residents 24 hours a day, 7 days a week, 365 days a year. That's a non-stop schedule of keeping the HVAC running and lighting on.

But if you're an engineer at one of these apartment buildings, here's the good news for you: if you haven't already switched to long-life, energy-efficient lighting, you may be sitting on a gold mine of savings by simply upgrading your lighting.

Interest in low voltage, or 12v, lighting has grown in our increasingly energy-conscious customers over the last several years, with the emergence and proliferation of long-life, energy-efficient lighting. 

But to properly understand the full benefits of low voltage lighting, we should start here: low voltage lighting is more of a tactical application than a budgetary or energy-saving one, though there may be moderate gains in these areas in certain instances.

This is the second in our series of articles meant to take the mystery out of savings and payback calculations for lighting. From designers to engineers to executives, lighting projects are more commonly cross-functional decisions.

This article focuses on one of the least-covered questions on savings calculations for lighting projects: How can a lighting retrofit save you money on HVAC costs?

We recently wrote about incandescent bulb part numbers, discussing the difficulties that come with translating a native language into a secondary language.

Some people say that there are certain languages that are easier to translate than others, because of how they are structured.
