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.

If chosen wisely, kitchen island lights take center stage and bring star quality to this multipurpose “heart-of-the-home” station.

From classic and traditional to clean and contemporary, island lighting makes a world of difference, enhancing the appeal and function of your kitchen space.  Over the breakfast bar or full service cooking station, island light fixtures and lighting controls should create balance and deliver a blend of general/ambient, task and accent illumination.

1.  Opt for energy-efficient task light with CFL (compact fluorescent) or LED (light emitting diode) pendant lamps centered over the island workstation.  Updated CFL and LED lamps are dimmable and available with improved color-rendering and color temperature.  Look for bulbs with a CRI (color rendering index) of at least 80 (100 is perfect color rendition) and CCT (Correlated color temperature) between 2700K and 3500K.

2.  Look for shielded, but focused illumination. Light sources should be non-glaring to provide even, shadow-free illumination.

Household appliances are expensive investments, so it's an alarming moment when the hot water heater sputters to a stop or the washing machine starts spewing suds all over the laundry room. If you're lucky, the problem is something that can be inexpensively repaired. However, sometimes your appliance is telling you it's time for a brand-new model. In fact, depending on how old your current model is, you could actually save money and come out ahead by purchasing a new, energy-efficient unit. How do you know when it's time to call the repairman, or time to pull the plug? Carefully consider your options when a machine is on the fritz: 

Do It Yourself

The first step is to read your repair manual and search online for people who have had similar problems. It could be that the issue is something simple that you can fix yourself. Things like clogged drains or filters should be an easy repair. 

Are You Under Warranty?

Lucky you. If your appliance is still under warranty, you may be eligible for free parts, a free repair or even a whole new unit, depending on the terms of your contract. Make sure to save all the paperwork when you make a major purchase, and read it over carefully before putting out any money for a repair. 

Call a Professional

If your appliance is only a few years old, it's probably worth the money to have a reliable professional come look at it and give you an estimate on what a repair should cost. Fixes like installing new motors or belts probably won't break the bank. If it's less than half the price of buying a new machine, it's probably worth it to fix instead of buy. Ask how many more years you can expect the appliance to last after a repair.

Time to Go Shopping

If your appliance is more than 6 or 7 years old, or if it's broken down numerous times in the past, it's time to start looking for a new model. If you are still coaxing an ancient, decades-old device into health, you might be shocked at how much you can save with an upgrade.

If you decide it's time to buy a new unit, do your research before you buy. The federal Energy Star program maintains a directory of products that meet strict efficiency guidelines, so you can be sure that whatever you buy will help tamp down your utility bills. Do some math to figure out how long your expected energy savings will take to cover the cost of the appliance. Also, don't forget to factor in any delivery or installation charges, plus the removal bill for the old unit.

Take Care of Your Appliances 

Finally, don't forget to read and follow all manufacturer instructions and keep up with any routine maintenance for your household appliances to extend their life and prevent breakdowns in the first place. A few minutes of work per year can save you hundreds or even thousands of dollars.

If the lights in your business are on their way out, making a change to your ballasts or bulbs may offer you tremendous opportunity. There’s a lot to consider when selecting the right ballast and bulb combination, however, and the decision you make today will affect your business for years to come.

The right lighting can result in substantial savings on your monthly energy costs, of which lighting accounts for nearly 35 percent. The right lighting can also reduce maintenance needs, improve productivity, and reduce your carbon footprint.

Watts measure the amount of energy required to light a bulb. Today, however, bulbs are measured in lumens, or the amount of visible light produced. Why? It all boils down to efficiency. Opting for ballast and bulb combinations that are more efficient than yesterday’s incandescents offer a superior return on investment.

There’s more to upgrading your lighting than simple bulb and ballast replacement, however. According to the SBA (Small Business Association), technology plus effective design equals performance and energy savings. Screwing in more efficient bulbs are a great start, but not enough if you want the whole package. Ballast selection and lighting design are essential to getting the most bang for your lighting buck. For this, you’ll need the help of a Mr. Electric® lighting professional to coordinate:
