LED sign lighting provides years of illumination and low energy costs. sign modules that consume 50mA of power each. Required materials differ depending on sign size, module size, length of wire between modules, current draw, and lumen output.

Materials:

1. First, measure your sign. Although we recommend spacing module rows 3 inches apart, it’s ultimately up to you. If you want a brighter sign, place them closer together and vice versa for a dimmer sign. With the recommended 3-inch spacing, a 4-foot square sign would need 150 modules (15 rows of 10). Again, the quantity of modules needed  is based on many factors and can differ.

These LED sign modules are available in custom lengths of up to 20 modules per strand. Order 60 feet (4 feet x 15 rows) of stranded modules, and cut the strand after every 10 modules. Each strand can be cut to make two rows.

2. Next you’ll need to order a power supply that’s rated for the combined wattage of all sign modules. To ensure that you don’t overwork the power supply, confirm that the total wattage of your modules is at least 20 percent less than the power supply’s rated wattage.

An easy way to calculate this is to multiply the total wattage of your combined lighting by 1.2. In the 4-foot sign diagram, there are 150 modules with a current draw of 50 milliamps (mA) each. Since current draw is given in milliamps, multiply that number by voltage and move the decimal 3 places to the left to get wattage. This module consumes 50 mA and has 12 VDC operation, so it consumes 0.6 watts (50 x 12 = 600). Next, multiply 0.6 by 150 to get a combined wattage of 90 and multiply that number by 1.2 (90 x 1.2 = 108) to determine which power supply you’ll need. Since the result was 108, you will need at least a 120-watt power supply.

3. Next on the list is wire to connect all your sign module stands to the power supply. For a 4-foot sign, you’ll need 4 feet of 18-gauge two-conductor wire to serve as your main line plus enough to cover the distance between your power supply and where it will be wired into an electrical system. You’ll also need dual-channel T-tap wire splice connectors for an easy connection to your main line.

Before you begin working on your sign, turn off power to the area.

4. If there isn’t one already, drill a hole in the back of your sign as an exit point for your wire.

5. Use a tape measure or ruler to plot your row spacing. Leave space on one side of the sign for your module-to-main-line connections. Mount the sign modules using their double-sided adhesive and/or screw holes.

6. Insert the end wires of each sign module row into the T-tap splice connector, and clamp the other end of the connector onto the main line. The splice connectors eliminate the need to strip wire insulation.

7. Use double-sided foam tape to secure each T-tap splice connector to the inside of your sign.

8. Reattach your sign’s front cover.

9. Connect the main line to your power supply, wire the supply into your electrical system, and restore power to the area.

There’s something exciting about making a large purchase: the rush of buying, the nagging fear that you can’t afford it, the anticipation of it making your life better or easier.  This feeling is especially true when it comes to a new appliance; it’s an investment in saving you time and effort. What if the investment you just made turns out to be a dud because of overlooking the impact it would have on your electrical system?

A lot of the work of an appliance happens within the machine, we tend to not think about the fact that an appliance is really a very complicated electrical machine. In addition, we ignore that they require a lot of electricity to operate. They can really strain your electrical system. This is especially true of modern appliances; it seems like they’ve found a way to computerize everything, and that only makes the power needs of an appliance grow even when they are “Energy Star” rated. Installation of these complex modern appliances seem as easy; some almost seem like they only need to be plugged in and forgotten. This approach neglects the fact that there are important things to keep in mind with regards to appliance installations that can cause serious problems for you down the line.

Obviously, you don’t always need to call an electrician whenever you install an appliance. With that being said, there’s nothing wrong with doing so if you’re not sure what you’re doing. The Best Dallas Electrician you can hire can help you avoid a lot of potential hazards and costs down the line. If you’re still planning on installing your new appliance yourself, keep in mind the following electrical safety do’s and don’ts:
