We all know or at least heard that converting from Metal Halide (High Intensity Discharge) to LED will save you money.

But how much? Are there any other reasons or difference you should know about?

In this article, we break down all the factors that you should be aware of before making a decision to convert from Metal Halide to LED. Here are the 9 reasons we think LED wins over Metal Halide.

Let’s take a look at the information on a typical 400 watt metal halide bulb. While specifications may vary, a visit to a popular online website that sells Metal Halide bulbs shows that a brand new bulb has the following specifications:

We have just as many customers wanting to convert to LED because of maintenance savings as they do for energy savings. Think about what we discussed, over the life of the LED retrofit kit, a customer would have to do 5-6 Metal Halide replacements. The higher the installation height, the higher the cost of replacement. And if you have a facility loaded with lights, this becomes a significant budget amount every year that you must take into consideration. Now, we know that reduced maintenance time on lights does not translate into dollars saved because it is highly unlikely that people will lose their jobs over the fact there is much less work to do. However, these people will have time to now work on things that matter, like fixing the machines that make the company money instead on replacing lights that cost the company money.

When you take a measurement of light with a light meter, it reads lumens. And this measurement of all the lights that contribute to the light at that location creates a measurement called foot candles. But let’s think about that light that is being measured. Metal Halide creates all sorts of light, in all spectrum’s, visible or otherwise. This includes UV and IR spectrum’s, visible to the measuring device but not visible to the human eye. LED, on the other hand, does not produce UV and IR. Therefore, its readings using the same light meter is only picking up visible spectrum’s.

So there is a fun little test you can do. Have 2 light sources, LED and Metal Halide. And first ask, which one is brighter? And if the right LED source was selected, they should say LED. And then use a light meter, and the light meter may say the Metal Halide area is producing more foot candles. And so now you know part of the reason, but wait, there’s 2 other pieces of information you need to know.

Conclusion

Across Nokesville and the rest of Virginia, parents and their kids anxiously await the arrival of Spring Break. The school year can be particularly stressful for everyone, both parents and kids, so we hope that you and your family are able to take full advantage of your downtime to relax. If you’re planning a getaway for your family, don’t forget to safeguard your home against potential threats. Getting adequate rest during this time is crucial for finishing out the school year strong. The last thing we want is for you to have to cut your vacation short because something went wrong at home. To get the most of your Spring Break holiday, follow these tips on keeping your home safe!

Whether you’re going to be gone for a few nights or the entire week, ask a trusted friend or neighbor to check on your home once or twice a day. Perhaps your neighbor can even keep a car parked there for the time being. You will also want to have your newspaper and mail picked up, as nothing says “I’m not home” like a driveway full of newspapers and a stuffed mailbox.

If you’re leaving pets behind, it’s especially crucial to have someone look after them. It’s always difficult determining just how much food and water your furry friend is going to need. For the safety of your pet – and for your peace of mind – make sure they’re properly taken care of!

Homeowners often make the mistake of leaving certain lights on at all times. While this may seem like an effective deterrent, it actually does quite the opposite. Wouldn’t you find it strange, too, if the same hallway and front room lights in a home were left on for several consecutive days? The goal is to make it appear as if someone is always home, so you want to follow a normal light pattern. You can do this by installing timers so that you can program your lights to turn on and off at designated times.

In addition to gaining control over your lights, by installing smart controls throughout your home, you can check to see if you remembered to lock the front door, close the garage, or turn the heat off. Even if you do have a friend or neighbor watching over your home, you might feel even better knowing that you can check on it too, even while hundreds of miles away.

If you live in an area where power outages are, unfortunately, quite common, you know just what an annoyance they can be. Sometimes, homeowners have portable generators they can plug a few appliances into so that they can stay at home. But for some longer outages, families have to leave their homes.

An automatic standby generator can power your whole house automatically! We recommend this to anyone who’s ever had to put up with a days-long outage, or for those who worry they one day will.

Portable generators can be useful during a power outage, but not for long. Fuel capacity is limited and depends on how much you can store at your home. The number of lights and appliances a generator can power is very limited, especially for larger homes and households.

Automatic standby generators use a transfer switch to detect a loss of current flow and automatically restore power to your entire home. You won’t have to do a thing!

Yes, a generator can cost a lot of money upfront. But the good news is that you’ll have it in your home for many, many years. It pays for itself if you save on losing refrigerated items, spending money on fuel and battery-powered appliances, or even hotel costs from moving out of the home for a day or even weeks.

Your home is a lot safer when you have a whole-house generator to protect it from flooding, burst pipes, and other issues. Keep the heat on to protect your pipes, continue operating your sump pump, and know that your home is safe.

In many cases, being without power for too long can actually lead to major safety hazards. Going without lights can be dangerous, particularly if you have kids or elderly family members. And many people with health issues can’t get by for long without heating or air conditioning—or without lifesaving medical equipment.

We often find there is a lot of confusion between Lumens and Foot Candles and Lux. And even more confusing is how some represent conversion from traditional light sources like Metal Halide and High Pressure Sodium in terms of watts, and not lumens. So why all the confusion. Well, it may be because those who represent this conversion are trying to avoid letting you know about the efficiency of the LED lights, so they claim you can replace X watts of Metal Halide with X watts of LED. What they should really say is that you can replace a 400W Metal Halide with X lumens, and their lights only need Y watts to produce these lumens. We’ll dive into this a little later, but lets first talk about lumens vs foot candles vs lux.

What is a lumen? A lumen is a measurement of light related to (1) fixture or bulb. So when we talk about lumens, we say that a fixture or bulb creates (X) lumens. These lumens are determined by sophisticated measurement equipment.

What is a foot candle? A foot candle is a unit of measurement at a specific location in a room or outdoor location that is created by 1 to many lights. It is a cumulative reading of 1 to many light sources at a specific location. It is both real and calculated. Real in the sense that you can take a light meter and walk to any location in a room or outdoor location and take a reading that represents the amount of light recorded from all contributing lights or fixtures. Calculated in the sense that you can use software to predict the foot candles of a space based on the placement of lights within the simulation.

What is lux? Lux is identical to foot candles. It is a measurement of real or calculated light, but it is done on a different scale. As a rough estimate, 1 foot candle = 10 lux.

So, simply stated, lights produces lumens, and the cumulative lumens of all lights are then determine the foot candle or lux measurement of light at a specific point in an indoor or outdoor space.
