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.

We all want the best for our children, and one of the most important ways we can help the next generation is by ensuring that they are receiving the highest quality education they can. But what if I told you there is an element to education that most people overlook when discussing ways to change education, even though it has been proven to improve behavior and focus, reduce disruptions and increase reading speed and learning capacity?

Though often overlooked, Research has shown that full-spectrum, cool white light is best for encouraging concentration in a classroom, so swapping out outdated fixtures for newer technology could be a great start to better classroom lighting.

Although fluorescent fixtures are popular in schools, the way they flicker (often imperceptibly) especially if a child has a visual impairment that necessitates a brighter environment. Try to position the lights (or the students) so that the task lighting is on the opposite side of their dominant (writing) side. This ensures that their writing arm won’t block the light, and distracting shadows won’t affect their work.

Teachers should try to avoid standing in front of lights or windows when talking, because these can easily distract or bother students. Though it can be difficult, students will focus and learn better when the teacher eliminates as many distractions as possible. And who among us hasn’t caught themselves drifting in a daydream out a window, whether interested in the topic at hand or not?

There are many programs and initiatives for better classroom lighting in place, though many are local to specific regions. Have you heard of any neat programs geared towards smart classroom lighting? Let us know in the comments!

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.

3) the 4) if you want your strip to be dimmable

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. Our teams are available from 8:30 a.m. to 8 p.m. CDT Monday-Thursday and 8:30 a.m. to 4 p.m. CDT on Friday.

Living in a small space may be challenging, but we like to take on challenges and make the best of what we have to bring out the beauty in our homes. From a studio apartment in Hoboken to a single-family home with a narrow eat-in kitchen in Palm Beach Gardens, we can help inspire you to make your home exactly what you want.

Maximizing storage and arranging furniture can dramatically enhance the space you have, and learning to use color effectively will also brilliantly expand the dimension of your room. Keep clutter to a minimum, add a few decorative statement pieces, and finish off the room with perfectly placed lighting.

Top Tips for Illuminating and Expanding your Decorative Interiors to Make Every Inch Count

Hang several sets of drapes along a wall to give your small room personality. This can work instead of paint and wallpaper. You will give the illusion that there are windows hidden behind the drapes, rather than just a wall or tiny window. You can also hang the drapes higher than the window sill to create a taller looking room.
