What is LED Lighting? An abbreviation for Light Emitting Diode, and still nobody knows what that means. From an engineer prospectus, it t is a semiconductor light source that emits light when current flows through it. Electrons in the semi conductor recombine with electron holes, releasing energy in the form of photons. Still unclear, well you're not alone, but please review the other questions to better understand the benefits of LED lights.
What are some of the benefits of LED light? A traditional light source like a fluorescent, metal halide or high pressure sodium requires an enormous amount of energy to produce light, however, LED requires very little energy. Also, the lifespan of a LED operating at a 40 hour work week, is calculated to last up to 24 years compared to only a few years using traditional lighting.
What is the maintenance savings? Frequent lamp replacements can be costly and maintenance savings is one of the primary drivers in the adoption of LED lights in markets such as street lighting and parking lots because of the long lifespan of LED’s compared to traditional lighting.
Why are lights so hot when I touch them? Traditional lights convert most of the energy into infrared radiation (IR) which radiates heat. LED do not emit IR, instead a heat sink removes the waste heat generated by the LED, which enhances the efficiency and performance of HVAC systems.
Are there any Emergency LED for homes? Most homes in Canada lack the most important emergency measure for protecting themselves, especially the children. When there is a fire and the home is filled with smoke, in most cases, the result is always fatal for the family. Our emergency lighting system is a stylist scone (located at our Online Interior LED) that gives you and your family 90 minutes of light when the power fails. You wake up to the sound of the smoke alarm, but your house is full of smoke and your disorientated, this one device will help you & your children find your way to safety and may be the importation survival device for your family to make it out alive.
What is Dynamic Human Centric Lighting? It is providing a specific light for a specific task in a specific space. Human Centric Optics, a Canadian company, produces dynamic human centric lighting. You, the user, at the push of a button, can control the LED lights to trigger a molecular reaction in your employees and customers to enhance their cognitive, concentration, motivation and alertness levels and also reduce anxiety, stress and other health problems at the workplace. It also resets a person’s body to its biological clock at the end of the day or shift to prepare for rest and regeneration at home. Widespread in Europe, there are only 3 manufacturers in North America, two from the USA and one in Canada.
What do they mean by Dark Skies Approved LED? Just like traditional lighting, LED is also guilty of light pollution. This pollution not only prevents us from star gazing, but disrupts insect and bird migration that is important to farmers, their crops and also maintaining an ecological equilibrium. So, a non profit organization was formed, called the International Dark Sky Association (IDA) which among other things, test and approve exterior LED lights that prevent light pollution.
So, when a Lighting company states their exterior lights are Dark Ski Complainant, it means it safe to use? That is a really good question, but unfortunately, that's not true. Many lighting manufacturers try to deceive you with spec sheets and brochures with terminology similar to what IDA uses. Don't be fooled with BUG optics, Dark Sky Compliant (DSC), Night-Time Friendly etc. If they do not have the Fixture Seal of Approval, then, they are not approved by IDA. .
Why do warehouses and office look so dark? Conventional lamps emit light in all directions, which can result in lower fixture efficiencies due to the light loss. Light emitted from an LED device is more unidirectional and controlled, meaning that fewer photons are trapped within the lighting fixture. LED sources can be easily targeted to illuminate parts of an object or area.
Are all LED fixtures made the same way? NO, many individuals are unaware of the proper certifications you need for your LED to operate safely and not cause any fire hazard. We have taken the steps to ensure you, the buyer, do not make the wrong choice by creating two categories on our online store for you to choose safely. 1. UL is the certification that is required for your LED to operate safely in North America. 2. CE is the certification that is require for your LED to operate safely in Europe and other international countries.
Are LED lights dimmable? LED luminaries can be designed with dimming controls and motion sensors to adjust brightness levels. LED can be dimmed more efficiently than fluorescent because the rapid and frequent on/off cycles do not affect its lifespan. These controls can reduce the operating hours of the LED system and lead to greater energy savings.
What is the durability of LED fixtures? LED sources produce light by passing a current through thin layers of a semi-conductive material. Inherent in this solid-state light production mechanism is the ability of the source to resist vibration, impact and adverse weather like humidity. That being said, when LED fixtures are not probably installed to allow air circulation or unknown power distribution in older buildings, it may negatively affect the lifespan of LED.
Will LED take a long time to turn on in cold temperatures? Good question, there is nothing worst than standing in the dark waiting for the light to turn on. A LED light will instantly turn on in any weather temperature and this is why an occupancy sensor paired with an LED is the best solution in lower your energy cost on your power bill. The LED performance inherently improves as operating temperatures drop. This gives LED outdoor lighting an advantage over other light sources as its efficacy increases when exposed to winter weather conditions.
Will a LED stop producing light if it fails? LED luminaries are made of multiple diodes and are less likely to fail simultaneously, which will in turn lead to less downtime. Users have reported fixtures with a certain amount of the diodes failing while the light is still producing full brightness.
Are LED lights safe? Yes, as mention earlier, there is not infrared radiation (IR) and all LED contain "no mercury" that require special handling for disposal. All LED luminaries are RoHS compliant. Most people are unaware that when one CFL or 4-ft fluorescent tube breaks, it is recommended that you shut off the furnace and call the local fire department for proper clean up because of the mercury that is released in the air. Most are unaware of the health risk regarding mercury because it can cause neurological disorders, emotional instability and other harmful conditions to humans, not to mention the mercury content in one 4-ft tube can pollute over 7,000 gallons of fresh water.
Why are some lights different colors and do they make a difference? Yes, they do make a difference. The rule of thumb is to ensure in residential homes, all LED lights should be 2700-3000 kelvin so that it provide a softer light for reading and allowing the body to release melatonin to promote healthy sleep rhythms. Business should be at 5,000 Kelvin to provide alertness and higher concentration. Exterior lighting should be at 5700 Kelvin on main roadways and business that need it for security cameras and to provide a level of safety to its clients. The higher K value will ensure the beam can cut through environment contaminants such as fog, rain, snow etc. It should be noted that business near residential areas and even residential roads should not have any exterior light above 3000 Kelvin. And, all exterior LED fixtures should have the IDA certification from Dark Skies. We do offer exterior LED lights that are IDA certified.
Is UVC light safe to use? NO, the FDA's position regarding UVC light, is the delivery method. In order for it to be effective, the light must shine directly on the surface and all individuals must leave the room and area before starting the disinfecting process. WARNING: No individual should be in direct contact with any UVC light during the disinfecting process, being behind a glass or solid partition is required as a safety prevention.
What makes a UVC light so dangerous? You do not want to be directly exposed to any UVC light because, when activated, the sterilization principle of a specific UVC ray will destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribose ribonucleic acid) in the cells of microorganisms, resulting in the death of growth cells or regenerative cells to achieve the effect of sterilization. WARNING: No individual should be in direct contact with any UVC light during the disinfecting process, be behind a partition or wear UVC safety goggles and apparel.
