A bit of mathematics at the end of the week. The

The first table shows three different installations. The old one is equipped with T8 fluorescent lamps that are at the end of their lifetime and dirty. That is why the luminous flux is so low for the 60W tube. In this situation, the need for a replacement is present. The choice is between a fluorescent tube, a LED tube or a completely new installation with controls. Controls reduce the average power consumption to 1/3 and less of the original load. We can estimate the new fixtures will consume 12W only when connected to controls that detect presence in the hall and reduce the lighting level in areas that are not in use. Each light point will be replaced. It is (often) possible to reduce the number of fixtures with a new installation. The example is concentrating on a one-by-one replacement to make it easier to understand.

The table above shows the sum of all costs for running and maintaining the installation each year and in total. The Retrofit Solution reaches an ROI after 2 years already. The New Installation with controls is going to turn back the high investment after 10 years. Both LED solutions do better than the conventional one, save energy and CO2 emissions. Let’s go green with LED light sources!

5-pin SPDT (single pole, double throw) automotive relay.

Relays are essentially two parts in one package. The first part is an inductive coil (pins 85 and 86). This coil is the “trigger” function of the relay. By applying both a positive (+) and ground (-) to the contacts, current passes through the coil. When current passes through the coil, a magnetic field is generated and moves the switch (the arrow in the diagram). This is where the second part of the relay comes into play.

The second part of the relay is the “switch.” The switch has three interface contacts—common, normally closed, and normally open. “Normally” refers to the state of the relay not being energized.

While relays can be used for virtually any task, there are some very useful, simple applications for adding LED lighting to a vehicle. Please note that this wiring only pertains to the relay—not the wires in the vehicle. Before interfacing with a wire in a vehicle, always ensure you test the wire with a digital multimeter first to confirm circuit function.

Positive Switching

Positive switching is used for applications where the “trigger” for your switch or circuit is positive. This could be an ignition, brake, or reverse light wire for example.  This could be used for applications such as off-road light bars, work lights, additional brake lights, and other exterior lighting.

Negative Switching

Negative switching is used for applications where the “trigger” for your switch or circuit is negative. Negative triggers are often found in door, hatch, and trunk triggers as well as many interior switches. This could be used for applications such as footwell lighting, truck bed lighting, under-hood lighting, and other interior lighting.

Switch Activated With Ignition Override

This is useful for applications where you want to turn your light on or off with a switch but only want the light to remain on when the car is running or key is in the “ignition” position. The main advantage to this is—even if the switch is left on—the light (or output circuit) will shut off when the key is turned off so that the battery will not be run down.

Strips with more LEDs per foot will consume more power.

In short, if maximum energy efficiency is what’s most important to you, choose a light strip with smaller LEDs and fewer LEDs.

In order to ensure your LED power supply doesn’t overheat and fail prematurely, we use this general rule of thumb:

Make sure the total wattage of your LED strip lighting is at least 20 percent less than the power supply’s rated wattage.

For example, if you have an LED strip light that requires 80 watts of power to run, you’ll need a power supply that’s rated for at least 96 watts.

The vast majority of our strips include wattage per foot right on their product pages.

power supplies range from six watts to 1,500 watts for compatibility with a wide variety of LED strip lights.

Let’s take a look at an example:

It’s important to verify that the voltage of the power supply you choose is compatible with the voltage of your LED strip lighting. Also, be sure that the power supply’s input voltage matches that of the location it will be installed in. If you have an LED strip with 12-volt DC operation that you wish to use in a 120-volt AC home wiring system, you’ll need a power supply that includes 120 volts in its input range and has 12-volt DC output.

Another factor to take into account for longer runs is voltage drop. A significant voltage drop is present after a certain distance of LED strip. After this distance, there will not be enough voltage present to light the next length of strip. This varies depending on the type of strip and length being used. Usually, a single-density strip (nine or less LEDs per foot) will need to run back to a power source every 32 13/16 feet (10 meters). A high-density strip (18 or more LEDs per foot) will need to run back to a power source every 16 3/8 feet (5 meters). Please refer to “Max Run” in the specifications table of the strip light to determine how many can be run continuously without a parallel run back to power.

power supply calculator on the product pages of all of our LED strip lights!

There are a few steps involved:

Step 1: Select your strip and the length you need.

Step 3: Click the green “Power Supply Calculator” tab, and select your product by choosing it from the list OR by pasting the exact part number in the search bar.

Step 4: Enter the number of strips at the desired length you’ve selected and voila! You’ll see a list of all compatible power supplies with the best match at the top of the list!

When dealing with electronics, safety is paramount, and you want everything to work like it’s supposed to. So if you’re still not sure which power supply to use for your LED strip lighting project, just reach out to our technical support team or customer service department at 866-590-3533.

Have you discovered your electric car is not saving you quite as much money on fuel as you had hoped due to the inability to get the car fully charged? Many electric car owners are discovering the typical 120-volt charging station isn’t enough to keep their car charged throughout their busy day. If you work somewhere there is a charging station and can get your car on the charger, you are set. But, if you are constantly on the go throughout the day or don’t have a charging station available to you, you need a better option.

Your electrician in Burbank can help you appease your car’s electrical needs by installing the necessary outlets needed to use one of the faster car charging stations. Unlike the more common 120-volt stations that you can plug into almost any outlet, the 240-volt chargers need something a little bigger. The Electric Connection can get you set up with the necessary outlet. Just give us a call.

If you are unsure what a 240-volt outlet is, think of your dryer or air conditioner. An electrician will need to inspect your electric panel first to determine whether or not your current panel has the capability of supporting the additional breaker needed. Typically, most newer houses do. The electrician will go about creating the proper outlet needed for you charging station.

If there isn’t enough room in the panel, you will need an electric panel upgrade. This is something you can discuss with your electrician. Burbank electric car owners can also count on The Electric Connection to install an outlet for the 120-volt chargers as well. Any charger should be on its own dedicated outlet to prevent overloading. If you need an additional outlet in your garage or carport, please give us a call today and we would be happy to schedule an appointment.
