A lot of time we are asked what is the equivalent LED product to convert from Metal Halide, High Pressure Sodium or Mercury Vapor. And a lot of time, we have a product in mind that works based on past experience. But how did we come up with that product, and how did we make the original decision on what was the proper replacement?

There’s a lot of science that goes into light, color, quality, and each light had it’s own characteristics. For example, it takes less LED to replace High Pressure Sodium than it takes to replace Metal Halide. And we are talking a lot more than just lumens. We are talking about color temperature, quality of light and something called photopic / scotopic lumens.

In the world of lighting, we measure foot candles with a light meter, this is called a photopic measurement. The light meter picks up everything, including spectrum’s that are invisible to us. Now, we humans see things to, and this is called scotopic lumens. Our rods and cones read and interpret light. And it does so differently than what a light meter does. So it is not uncommon when we demo a LED Light against a HPS light or Metal Halide, we first ask “Which is brighter” before we show the light meter reading. It leaves a few people scratching their heads. Well, that’s the science of of it all, and fortunately there is some handy tables called SP ratios that allow us to take the lumens of a particular light (photopic lumens) and multiply it by the S/P ratio to get the scotopic lumens equivalent.

For example, the S/P ratio for High Pressure Sodium is 0.40. The S/P ratio for LED at 5000K is 1.8. So if you take 40,000 lumens of HPS and multiply it 0.4, the effective scotopic lumens is 16,000. To get the same amount of lumens from LED, take the 16,000 and divide it by the S/P ratio and you get 8888 lumens. So the 8888 lumens of LED is the photopic measurement, the 16,000 LED lumens is the scotopic lumens measurement. So in an nutshell, you need 8,888 lumens of LED to replace 40,000 lumens of HPS from a scotopic point of view.

Here is a handy chart of common lights and ratios for you to use.

We’re proud to announce the arrival of new high-CRI architectural retrofit LED downlights. The LED lights are available in a variety of sizes and wattages for applications ranging from retail, commercial, grocery store, hospital, and auditorium lighting to bathroom, basement, and kitchen lighting. Can light replacements have integral junction boxes with round and square knockouts, and architectural downlights are equipped with driver enclosure boxes. These energy-efficient LED lights can be easily wired to code and are IC rated for safe contact with insulation.

Flush or Semi Flush?

Flush mount and semi-flush mount lighting fixtures are integral components in lighting design, adding interest and depth while providing ambient illumination and decorative lighting effects to hallways, bedrooms and bathrooms.

The difference between a flush and semi-flush light fixture is that a flush fixture fits snugly to the ceiling, while a semi-flush fixture is suspended, leaving a small gap between the ceiling and fixture.  Opting for a flush or semi-flush light fixture is based upon taste and proportional considerations, but a few standard rules apply:

♦ Semi-flush—Somewhere in between the chandelier and standard ceiling fixture, the semi-flush fixture shines with distinction.  Taking up just the right amount of space with the power to attract desired attention, the latest semi-flush light fixtures provide superb illumination with artistic excellence.

♦  Semi-flush fixtures provide an added benefit: the small gap allows for double the illumination with indirect uplight rebounding off the ceiling and downlight emitted directly from the fixture.

♦  Flush fixtures—Most often employed in homes with standard 7-foot ceilings to provide general illumination for bedrooms, bathrooms, foyers and hallways.

Novel compositions and unique finishes are available at a variety of price points and are being featured from top lighting vendors around the world, making it easier than ever to find ceiling light fixtures in keeping with your budget and style requirements.

You have probably heard a lot about green living lately. The term is pretty broad, but basically, it means learning to be more reliant on renewable energy sources and protecting the environment and in many cases, saving a few dollars. Green homes are one way you can fulfill all three of these things.

Green Home

What is a green home? It isn’t a house painted green! It is a home that relies on a renewable power source, like the sun. Solar-powered homes use to be very rare. However, in today’s tough economic times and the rise in electric costs, they are quickly become a viable option. An electrician in Burbank can help answer any questions you may have about solar power and what it can do for you. The experts at The Electric Connection are here to talk with you about your options and explain to you how it all works.

Solar Power

Solar power isn’t what it used to be. Nowadays, the panels are relatively small, but just as effective as their predecessors. Many homes rely solely on solar power combined with backup generators. However, if you are not willing to completely give up your connection to the power grid, you don’t have to, but you can still use solar power for the majority of your power needs. This is something you will want to talk about with your electrician. Burbank residents know the value of saving a dollar and with solar power; you will certainly save more than a mere dollar.

There is an initial investment cost to installing a solar power system with panels. However, this investment is well worth it. Imagine what it would be like to cut your electric bill in half every month? If you are interested in learning more about solar power, please call us at The Electric Connection. We would be happy to provide you with the specifics needed and your options.
