One of the main stays in Industrial and Commercial Lighting has been the Metal Halide Bulb. It is common in Indoor Fixtures, such as High Bays, Canopy Lights, Garage Lights and Low Bays. It is

So you have a Metal Halide (or even High Pressure Sodium) light, and you want to convert to LED. You’ve done your research, you’ve been inundated with marketing materials that tell you what is the most important thing to consider (coincidentally it probably is something they think is important). And now you are left to make a decision. New or retrofit? What new versus retrofit. We sell both. Our retrofits perform as well if not better than new fixtures, but not all retrofit kits can make that claim. However, if your fixtures are old, leak, and have seen their better days, then by all means replace them. It does not make sense to buy a new fixture that includes a retrofit kit inside of it like some vendors will try and sell you. The engineering of some of the new fixtures are fantastic. However, the real reason you would want to consider retrofitting is because you have a significant investment in fixtures. Why not keep that investment? Retrofitting is extremely cost effective, especially our Look for the DLC Premium Symbol, it’s different than the DLC Standard symbol. And that gives you the quick notification that the light you are looking at is the most efficient.

And why does that matter. It’s simple. It will save you a lot more money. Let me do three comparisons for you. First a retrofit kit designed at 97 lumens per watt to replace a 400W Metal Halide bulb, a second at 102 lumens per watt and ours at 155 lumens per watt. Lets keep everything else the same. Cost of electricity, hours of use. The only thing different you will notice is the watts consumed and the lumens produced. For the record, our retrofit kit uses the least amount of energy in this test BUT also produces the most amount of light. We will use 12 hours a day operating time and .12 kw.h electricity cost

Calculation 1: 97 lumens per watt retrofit head, 135 watts, 13164 lumens

Savings per fixture per year over 400 watt Metal Halide: $170.82

Calculation 2: 102 lumens per watt retrofit head, 143 watts, 14600 lumens

Savings per fixture per year over 400 watt Metal Halide: $166.62

OK, so between the competitor options, you are neck and neck, the difference is so minimal you can make your decision based on whose website you like more

Calculation 3: 155 lumens per watt retrofit head, 100 watts, 15,776 lumens (this is our LED Retrofit Kit)

Savings per fixture per year over 400 watt Metal Halide: $189.22

So there is clearly a $18.40 savings over the first LED retrofit option and a $22.60 savings per fixture over the second LED Retrofit option. And, we produce more light!

We have 3 mini LED Retrofit Kits, 30W, 45W and 60W designed to replace up to 250W Metal Halide. We have 3 standard sized retrofit kits, 75W, 100W and 120W designed to replace from 250 Watt to 400 Watt Metal Halide. We have 2 Large Retrofit Kits, 150W and 200W, designed to provide more light than a 400W Metal Halide up to 750W Metal Halide. And we have 3 Extra Large retrofit kits, 280W, 320W and 350W, designed to replace 1000W Metal Halide.

Energy efficiency starts in the home, but the policies and practices of your local municipality play a big role as well. The American Council for an Energy-Efficient Economy (ACEEE) recently compiled an efficiency ranking for 51 of the largest cities in the United States, looking at local government operations, community-wide initiatives, buildings, energy and water utilities, and transportation. The scorecard is mostly concerned with policy actions at the government operational level, but the criteria have an effect on consumers as well, through areas like building codes and efficiency incentives. Read on to find out where your city ranked.

Boston Takes the Crown

You don't have to be a master electrician to understand that saving energy means saving money. It also means less impact on the environment through fossil fuel-induced climate change. Therefore, top cities are being both fiscally sound and good members of the world community.

Boston is the top city for efficiency, followed by New York City and Washington, D.C. Washington was also one of the three most improved from a 2013 report, along with Los Angeles and Chicago. Bringing up the rear of the 51 cities ranked are Raleigh, Birmingham, and Oklahoma City.

“Our findings show that cities continue to be laboratories of innovation when it comes to energy efficiency, with many pushing the envelope for more energy savings in the last few years,” ACEEE research analyst David Ribeiro said in a press release. “Cities are also improving their approaches when it comes to tracking and communicating their efforts to save energy.”

Find Out Where You Rank

If you live in one of the ranked cities, you can check out how your community performed. If your municipality didn't make the cut, the organization encourages interested participants to fill out a self-scoring tool to help build up their data.

For each city that does show up in the rankings, you can drill into the information and see where they did well and where they came up short. For example, Philadelphia, slotted in 14th place, got credit for its government sustainability plan, its tracking of energy use for large buildings and its comprehensive public transit system. It scored lower in the community initiatives area, among other places.

What it Means for You

The building and community initiative sections are particularly relevant to homeowners. Building codes, of course, dictate what you can and can't do when constructing or adding on to a house. More stringent codes can mean more red tape, but they can also make buildings more efficient overall, which can save consumers money in the long run. Community initiatives, meanwhile, refer to programs that encourage, track or incentivize efficiency measures, which can take the form of elements like rain barrels and tree-planting programs.

You don't have to lobby your city government if you want to make an impact on energy efficiency in your own life. There are plenty of initiatives you can take to cut back on electricity use around the home and become an energy-saving master. Electricians will marvel at how low your bills are if you take just simple steps like using Energy Star-compliant appliances and unplugging your devices when they aren't in use. For even more ideas, have a master electrician conduct an energy audit on your home today. The expert electricians at you local Mister Sparky® are always here to help!

Every commercial space, whether it’s a hotel, restaurant, office, department store, small shop, school, or hospital, can benefit from switching to LED lighting. LEDs are energy-efficient alternatives to halogen, and Universal LED Bulb Finder to search by bulb type, or browse our site to see hundreds of lighting options.

There are many LED recessed lighting options for existing can lights, eyeball lights, or other recessed commercial applications. Traditionally, recessed fixtures contain either a PAR halogen bulb or a BR incandescent bulb. These bulbs are available in several different sizes, and each type has its own set of features. BR bulbs typically have wide flood beam patterns and allow for more of a gradual fade of light. LED replacement PAR and BR bulbs have those same features but with increased energy efficiency and longer life spans. Complete LED fixture replacements, such as downlights, are also an option.

When it comes to commercial lighting, one of the most popular fixtures is the fluorescent panel light with T8 tubes. These panels offer little in the way of quality lighting. Hot spots are visible even through their textured lenses, and the light that they emit has a yellow-green hue. CRI), which is the key to showing the true colors of objects and surroundings. They emit crisp, clear illumination with no visible hotspots, and you won’t have to worry about replacing them for a very long time.

It’s no secret that a well-lit sign will stand out more than one that is poorly lit. LED sign modules are available in many different intensities and colors to illuminate signs, light boxes, marquees, and channel letters. Because LED bulbs can last up to 25 times longer than incandescent or halogen alternatives or approximately five times longer than fluorescent tube lights, the need for replacements is few and far between.
