Everything you want to know about LED lighting
Welcome to our LED FAQ section. Here are some answers to your most popular questions.
LEDs bring several advantages to the lighting industry, including high efficacy and durability, and with superior life over other bulbs, their required maintenance is greatly reduced. This translates into energy savings, maintenance savings and environmental sustainability. There is also the potential for greater optical control, dimming, instant on & off and reduced rate of lumen depreciation (potential for long application life).
Studies show that natural sunlight has a positive impact on our body and mind by strengthening the immune system, metabolism, blood pressure and blood sugar levels. Everyone will confirm that they can see and read better in sunlight than in traditional artificial light. Under full spectrum light, colours are rendered true to the original and the contrast is very sharp. The full spectrum not only provides optimal color reproduction and good contrast, even more it provides positive influence on your mood especially during the dark winter season.
Full-spectrum light contains – unlike conventional light sources – almost all light colors and proportions, as they are known and enjoyed from sunlight. The true color reproduction and high contrast resolution (5500K with CRI> 90) in conjunction with a full, harmonious, natural daylight color spectrum ensures optimal support at work, unparalleled reading comfort and creates a climate of well-being in every room.
LEDs are dimmable. Please refer to individual product descriptions where it will confirm if they are dimmable.
LEDs do not contain mercury, as with all electronic appliances, they should be recycled at an approved facility.
Our LEDs’ are brighter than the light bulbs you are looking to replace. The Spectrum, color temperature and colour rendering of our full spectrum light bulbs is close to that of natural daylight at noon.
All of our products that have an EnergyStar category are EnergyStar approved.
LEDs’ work in a completely different way to traditional lighting as they typically use 75% less energy while producing the same amount of light.
An LED does not burn out like a standard lamp, so individual diodes do not need to be replaced. Instead, the diodes gradually produce lower output levels over a very long period of time. If one LED fails, it does not produce a complete fixture outage.
No. Unlike incandescent and fluorescent lighting which will fail sooner when switched on and off more often, LED lighting is unaffected by how often it is switched on and off.
LED fixtures must be designed with junction temperature thermal management as a key component and use the correct LEDs. These products will then be robust enough to operate in most ambient temperature applications. Unlike fluorescent sources, cold temperatures do not impact the performance of LEDs.
Based on how long a fixture is illuminated per day, here’s what 100,000 works out to:

Gorgeous lighting from LEDs? It’s true – an innovation that illuminates people and surroundings in color-rich light. Experience all the benefits of incandescent lighting, without high energy costs or environmental impact.
Colors Fully Revealed
It’s not your imagination – it’s science. Our LED lights do look more natural than CFLs. LED lights have a higher color rendering, so everything under them looks more vibrant and lifelike. Choose warm or cool lighting. Warm lighting gives a traditional and luxurious feeling that homeowners have come to expect. Cool lighting creates an effective work environment or brings a contemporary look to a home.
Hotspots, No Glare
LED lights from diGIO Lighting Solutions are designed to blend seamlessly with any architecture. The proprietary diffusing lens and reflector system deliver an optimal light distribution that softly washes walls and sufficiently illuminates work surfaces. LEDs are not visible, so you won’t be distracted by hotspots or glare. The only thing you’ll experience is life under beautiful, glowing light.
Useful life has been defined as the number of hours an LED device can operate until it emits only a certain percentage of its original lumen output. For general illumination applications, vision research suggests that 70 percent of original lumen output is the level where end users begin to notice a drop in light levels. This metric is indicated as L70. The Illuminating Engineering Society of North America (IESNA) published LM-80-08, IES Approved Method for Measuring Lumen Maintenance of LED Light Sources. Our LED lamps have been tested for long-term lumen maintenance consistent with LM-80 methods to demonstrate L70 life after more than 6000 hours of testing and got the number 50,000 hours under normal operating conditions. Also the performance of all of our products is verified by accredited independent 3rd party laboratories. Please note, any initial condition or parameter change will affect the useful life of LEDs in different ways.
Light-emitting diodes (LEDs) are solid-state lighting components. Each LED consists of a semiconductor diode that emits light when a voltage is applied to it. They have no moving, fragile parts and can last for decades. LEDs can be many times more energy-efficient than light bulbs, depending on the application. LED lighting can save up to 85 percent of the electricity used by incandescent bulbs and up to 50 percent of electricity used by fluorescents.
The electronics industry has used LED technology for several decades as indicator lights for various electronic devices. In more recent years, LED technology has progressed to the point where it is viable for general lighting applications.
Most of the energy emitted from incandescent bulbs is converted to heat instead of light. That’s why you’ll burn yourself if you try to touch an incandescent bulb once it’s turned on. Since LEDs consume significantly less energy, they don’t emit as much heat. That’s why you typically won’t burn yourself if you try to touch an LED light once it’s turned on. LED lights are also designed to last about 50 times longer, which means less ladder-climbing maintenance and less waste.
Color Rendering Index (CRI) is defined as a light sources ability to render color. The higher the CRI, the better the light source renders every color in the visible spectrum. To have what is generally considered good color rendering, a source must be >90 CRI.
Junction temperature is the temperature at the point where an individual diode connects to its base. Maintaining a low junction temperature increases output and slows LED lumen depreciation. Junction temperature is a key metric for evaluating an LED product’s quality and ability to deliver long life.
The three things affecting junction temperature are: drive current, thermal path, and ambient temperature. In general, the higher the drive current, the greater the heat generated at the die. Heat must be moved away from the die in order to maintain expected light output, life, and color. The amount of heat that can be removed depends upon the ambient temperature and the design of the thermal path from the die to the surroundings.
Heat management and an awareness of the operating environment are critical considerations to the design and application of LED luminaires for general illumination. Successful products will use superior heat sink designs to dissipate heat, and minimize junction temperature. Keeping the junction temperature as low as possible and within manufacturer specifications is necessary in order to maximize the performance potential of LEDs.
LEDs are environmentally friendly on many fronts. First, unlike HID (High Intensity Discharge) lamps, LEDs contain NO mercury. In addition, some LED luminaires are RoHS (Restriction of Hazardous Substances) compliant and have been designed to provide more than a decade of near maintenance-free service. That means no re-lamping which means no waste.
Assuming an HID fixture is re-lamped every two years, that’s five re-lamping cycles over a 10 year period. Just imagine the benefits of choosing LED:
- No concern over proper disposal (hopefully not simply thrown in a landfill) of old HID lamps containing harmful mercury.
- No fuel used and the accompanying pollution to service those fixtures.
- Greatly reduced potential for lane closures and other productivity and inconvenience-related costs associated with maintaining an HID system.
- No natural resources lost to produce the replacement lamps that contain mercury.
- No fuel used to move old-technology lamps from the factory (most likely overseas), to the distributor, to the contractor, to the job site.
It’s important to keep in mind all the positive and powerful ripple effects that using LED technology can have on the environment.
The life span of an LED is vastly longer than that of incandescent, fluorescent or HID lamp sources, generally lasting 50,000 hours or longer. Although the LED never really burns out, product life span is measured by lumen depreciation.
The Illuminating Engineering Society’s (IES) current standard for calculating the life of an LED as the point at which the LED reaches 30 percent lumen depreciation.
Remember, a 100,000-hour rating is not equivalent to lamp life rating. LED life is rated where it has reached 30 percent lumen depreciation. At 100,000 hours an LED would still be operating, but at a decreased lumen output.
Yes. LEDs are very similar to consumer electronics and quality really matters. In order for an LED to function properly and provide an acceptable light output, all of the components must be built to last. It’s always a good idea to buy from a manufacturer and retailer that you’re confident will stand behind the product.
