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.

Weather is so unpredictable, even trained weather people struggle to accurately predict storms and the strengths of those storms. It just makes sense to prepare for anything in order to keep your life as normal as possible.

A Pasadena electrician can help you protect your appliances, computers and televisions with the installation of a whole home surge protector. If you have never heard of one of these devices, give The Electric Connection a call to discover how they can save you hundreds of dollars by preventing damage to your electronics.

Every single day, there are power fluctuations in your home. This may be caused by large appliances like a refrigerator or air conditioner kicking off and on or things that are happening around the area. These minor power surges are not always noticeable, but they are damaging the sensitive electrical components in each of your devices. This can shrink the life expectancy of certain high-dollar appliances like your refrigerator, well pump, freezer and even the stove. More sensitive devices like computers, smart TVs, and gaming systems are easily damaged by these minor power surges.

Large surges can wipe out a computer board in an instant. Every electrical device has a board. When this happens, the appliance or gadget is ruined and will likely cost hundreds of dollars to repair. All of this can be avoided with a surge protector installed at the electric panel by an electrician. Pasadena homeowners can purchase a whole home surge protector for a couple hundred dollars.

Anytime you find yourself wanting an electrical safety inspection, it’s important to know what kinds of questions you need to ask. A lot of the time people are stuck with hidden fees or things that they are unaware of due to the lack of curiosity. Even if it seems so simple, it’s always best to ask the right questions to an electrician especially when it comes down to your home’s safety and your family’s well-being. When you see the lights start to flicker or your outdated electrical system giving you trouble, it’s time to call for a repair or maintenance check. Having an electrical safety inspection by a professional contractor will help flag any warning signs that might arise in the future. So here are some questions that can prepare you so you know what to ask when it’s time to conduct an electrical safety inspection.

Usually, when we want to hire somebody we always like to know that who we’re hiring has had an education within that field. However, when it comes to hiring an electrician to conduct an electrical safety inspection, experience and how much of it is especially important. Experienced professionals not only have seen a lot and can provide effective solutions, but they also recognize the importance of high-quality performance and customer service. By asking about their experience, you’ll be able to determine how qualified that contractor is to handle your electrical safety inspection.

When it comes time for an electrical safety inspection, you want to make sure hire an electrician that has a valid electrical contractor’s license. This will make you feel more comfortable knowing that the person you’re hiring is educated and trained to perform a high-quality electrical safety inspection since they are being held to a high standard as a licensed professional.

During an electrical safety inspection, things may come up where the electrician might either want to fix or restore a certain business. So, asking about an estimate and whether additional work is covered is always a great question to ask.

When you’re looking for an electrician, look for someone with whom you can form a long-term relationship. It’s going to save you a lot of time and money if you can find someone whom you trust to get the job right the first time and give you the right price.

Find Recommended Companies

You can get recommendations for electricians from friends and neighbors. You can also search on-line for electrician Beverly Hills CA, and so on. If you add the word reviews to your search, you can look through company reviews.

Another approach is to search websites that feature reviews. Reviews appear on many websites including Google Places, Yelp.com, AngiesList.com, and CitySearch.com. AngiesList.com is an excellent source of recommendations for contractors but requires a small annual membership fee. On Angie’s List, you can see how customers rated their contractors, including electricians, and details of how their jobs went.

When looking at customer reviews, take a look at the big picture. Is there one bad review among the many good ones? Is it just a grumpy customer? Is there a company reply that clears things up or says that it has corrected its employee?

Once you have three or so recommended electricians, take a look at their websites.

Check the Electrical Company Website

* Is it presentable and well-maintained?

* Easy to find what you’re looking for?

* Friendly, helpful, and not cluttered with hard-sell advertising?

* How many good testimonials?

If the website checks out, it’s time to interview the electrician.

Interview

When you talk with the Beverly Hills electrician, pay attention to how comfortable you are, including your trust level. I’ve listed questions that you can ask. If you’ve already gotten glowing recommendations or it’s a small repair job like fixing a broken light switch, you probably wouldn’t want to ask them all. But if you aren’t talking with a recommended electrician and you’re planning a remodel, ask away.

Experience with your type of work

Years in business. Most companies which have stayed in business a long time have managed to keep their customers satisfied. They’ve also gathered a lot of useful experience and competence.

* Contractor’s License Number

* Liability Insurance and Workers Comp Insurance. It’s desirable that the company carry at least $1 million in liability insurance to protect your home should their work create property damage. Workers Comp provides for medical care for the electricians should they be injured on your job. Again, this protects you from liability.

* Guarantees. Some companies offer a lifetime guarantee on their work. This wouldn’t generally include the electrical parts that they install – that’s covered by the manufacturer’s guarantee. However, the electrician should give you at least a several-year guarantee on labor. A guarantee up to the life of your home is best.

* Better Business Bureau (BBB) rating. Ask for the exact company name that you should look and in which city. Sometimes, the BBB will use a slightly different name, possibly the formal legal name of the company.

* Pricing

* Website address if you don’t already have it

* Names and contact info for five clients

Take notes on all this, particularly the License Number. If you decide to go ahead, you may wish to check some of what the electrician has said. If you decide not to go ahead, no need to proceed any further with this electrician in Beverly Hills CA. But save the notes so that you can remind yourself later of which companies you’ve already ruled out. The Electric Connection, a licensed Beverly Hills electrician, is a top choice for a dependable electrical contracting company.
