What Are Lumens?

What Are Lumens? In general, lumens (lm) are a measure of how much visible light a specific light source is emitting. Therefore, the higher the lumens, the more light a source will emit. This measure is extremely important for several reasons, especially within the LED lighting industry.  Why Are They Important? The first and most important reason for understanding lumens is ensuring accurate and complete lighting of a certain space. For example, if a parking lot emits lower lumens than needed, you may sacrifice lighting in certain areas creating safety concerns. By working with Integra LED, we can help you choose the perfect lighting system for your space.  LEDs and Lumens A common way to measure the efficiency of a lighting option is dividing lumens by watts. The larger the number, the more efficient the lighting option will be. LED lights are currently the most efficient lighting option due to their low wattage requirements.  For example, a common HID will produce 15,049 lumens using 320W giving it a lm/W of 47. On the contrary, an LED high bay will produce the same number of lumens with only 122W giving it a lm/W of 123. Therefore, a common LED high bay is around 2.6x more efficient than a common HID high bay. Overall, when considering which lighting option to choose, LEDs are the best option because they offer the most light for energy used making them more efficient and cost-effective.

What Is Color Temperature?

LED Lighting has seen many advancements over the past couple of years leaving consumers with many options to customize their lighting. One of the most notable options is the ability to choose and or adjust the color temperature of your LED lights. In this blog, we will cover what exactly color temperature is and how to select the best color temperature for your facilities lighting. What Is Color Temperature? Color Temperature is a measure used to describe how “cool” or “warm” the light being emitted from a source appears. The spectrum ranges from 1,000K (Amber) up to 10000k (White) but most applications stay between 2,000K – 6,500K. Below is a simple chart we created to help visualize the differences in color temperature.  IntegraLED, NewYork, Latham, CustomEnergyServices, SmartControlSystems, LEDLighting, EVChargingStations, The exciting part about modern LED lighting is that you can customize your lighting based on your preferences.

Color Rendering Index (CRI)

Color Rendering Index or CRI is a measure commonly used in the LED lighting industry. In general terms, the Color Rendering Index measures the ability of a light source to accurately reveal the colors of objects in comparison to natural light. CRI is measured on a simple 0-100 scale, the higher the CRI, the better the light source will render color. Therefore, an ideal light source will have a high CRI preferably above 80.  Why is it important? Color Rendering Index is vital in applications where consumers are viewing or interacting with physical products. For example, a grocery store with inefficient and low CRI fluorescent fixtures will make produce look drab and unappealing. By switching these bulbs to efficient and high CRI LED Lighting Fixtures, the produce color will pop and attract consumers. A European supermarket utilized LED spotlighting and color LED uplighting to increase stopping power by 15% which lead to an overall sales increase of 6%. On top of this, LED lighting can greatly increase the energy efficiency of your location. Our customers have seen lighting cost reductions up to 70% Where Can I Find a Lights CRI? Most LED lighting manufacturers display the CRI on the front of the box or the back where they highlight different key measures including lumens, life hours and color temperature. The example below shows common packaging for an LED light and where you would find the CRI.  What Light Source Should I Use to Increase My CRI?  Natural light will always be the most ideal source to ensure the colors of your product are represented properly but unfortunately, many spaces do not have that luxury! LED lighting is a great option for any facility because it is more energy-efficient than other light sources and offers high CRI options. High CRI LED lighting can greatly increase the attractiveness of your products while saving you money at the same time! 

Do You Know What You Are Putting in Your Ceiling?

Over the past five years, the LED lighting industry has seen an explosion in growth. LED technology has become more affordable and efficient making it the best lighting option for any space. This growth has created intense competition within the industry putting pressure on businesses to find a way to stand out. The most common way is price, but many companies have begun sacrificing the quality of their products to do so and even lied about the components used in their lights. In this week’s blog, we discuss what you as a consumer should be looking for when purchasing LEDs and why cheap products can create a safety risk for you.  Counterfeit Drivers  In general terms, LED drivers are a power supply that provides proper voltage and protection. Depending on the application, drivers can be contained within an LED light or externally wired to the light. A bad driver can send too much power to a light causing it to overheat and fail. Furthermore, they can reduce performance and cause aggravating issues such as delay and flickering.  So how does one know if a driver is quality and can be trusted? The first step is checking for efficiency standard designations such as UL, DLC and more. The goal of these organizations is to ensure the safety, efficiency, and quality of lighting products for consumers. They perform various tests with strict criteria to find which products fit their standards. If they pass, the product can be stamped with their logo so customers can identify their listing and know the product can be trusted. We highly recommend visiting the DLC and UL websites and researching if the products you have previously installed are listed. Furthermore, there have been cases of LED products that place fraudulent efficiency standard designations on their products so doing your research is quite important. Check out this interesting article about a company that was fraudulently placing UL logos on their drivers. https://www.prnewswire.com/news-releases/ul-warns-of-counterfeit-ul-marks-on-led-driver-release-17pn-09-300474481.html As stated in the first paragraph, many LED lights internally contain their drivers. This is extremely convenient because it makes replacing an outdated light a one-step solution. The downside is that companies commonly promote their drivers as “high-quality” and use cheap drivers knowing the end-user will never actually see it. The best way to verify this is by checking if the product is listed or consulting with a company like Integra LED who can quickly assess product legitimacy and quality. Luckily, lighting consultants like Integra LED complete all this research for you and only install listed lighting products to ensure your LED lighting upgrade is safe, efficient and will last. Many facilities have numerous types of lights making the research process quite time-consuming.  Cheap Materials and Construction LED lights are comprised of several components that all play a factor in how long they will last. For example, LEDs perform better in cooler temperatures so quality heat sinks can greatly increase their performance and rated life. Budget or cheap LED lights commonly skip out or cut corners on these key design features to offer a more affordable product. The price tag might look attractive but when your lights start quickly burning out or even catching on fire, you may regret that $2 dollar difference.  Don’t believe us? Check out this tube that caught on fire which we found while completing an energy assessment for a potential customer. We won’t name names but is readily available and commonly purchased by businesses who complete “DIY” upgrades. The moral of the story is that if the price is suspiciously cheap, the product is either counterfeit or poor quality. We expect this issue to grow as LEDs begin to saturate the lighting market and become the most utilized source of artificial light. Protect your facility and work with a lighting consultant to upgrade your lights to LED. Our projects are backed by a minimum 5-year warranty and we only install listed quality lighting products to ensure your facility is safe and efficient.

LED Lighting Applications: Manufacturing

LED Lighting Applications: Manufacturing Integra LED has worked with numerous manufacturing facilities over the years offering quality lighting solutions. Over this time, Integra has gained insights on the best solutions for manufacturing facilities to help them receive high-quality lighting that significantly reduces lighting costs. In this week’s LED Lighting Application, we will discuss some of the best insights we’ve received while working with manufacturers!  Common Replacements  We commonly replace high-intensity discharge lamps also known as HIDS as well as fluorescent troffers. These two options are extremely outdated, they are up to 70% less efficient than modern LEDs and offer an inconsistent and unreliable source of light. When it comes to lighting for manufacturing spaces, we commonly replace the entire fixture with a one-piece LED solution. Below are two examples of upgrades we install for customers.  HID Lamp Upgrade LED high bays are a great solution for outdated HID lamps. As you can see in this example, the LED option will last around 3.8x longer than the HID lamp while using almost 70% less electricity. Furthermore, HID lamps have a long start time which can slow down employees whereas LED high bays turn on instantly saving your company time and potentially money!  Fluorescent Tube Upgrade  LED tubes are the most common upgrade we see here at Integra LED. They let the facility keep the original troffer they have because tube replacements only require new drivers and LED tubes. As you can see above, LED tubes are significantly more efficient than fluorescent tubes. In general terms, efficacy is a ratio comparing light output to energy consumption. Therefore, the higher the ratio, the more efficient the light source is.  Safer Employees  Considering the number of hazards in a manufacturing facility, safety is a priority for your employees. Put yourself in the shoes of an employee, you are handling dangerous machinery that cuts raw materials. It requires a high level of precision and needs you to move quickly to avoid bottlenecks in the manufacturing workflow. In situations like this, employees need an environment they can focus in and safely handle the dangerous machinery they are using. Lighting is a major factor in employees’ safety as well as productivity in situations like this. If an area is underlit or improperly represented due to a low color rendering index (learn more here), it can create risk for your employees due to poor vision or focus. Furthermore, fluorescent lighting is commonly linked to headaches and other cognitive issues that can affect an employee’s focus and overall health.  LED lighting is the most modern and efficient solution for manufacturing lighting systems. Integra LED has installed countless systems for manufacturing spaces and seen tremendous results. On average, our customers reduce their lighting costs by up to 70% and get up to 35% of their project cost covered by incentives.
