What are the advantages to using LED luminaires?
LEDs bring several advantages to the lighting industry, including high efficacy and durability, and, with superior life over other lamp sources, 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 (more controllable source), dimming, instant on/off, and reduced rate of lumen depreciation (potential for long application life).
Are LED lights ultra-efficient?
Compared to conventional technologies, LED Light products can deliver the same amount of light using as little as 10 to 30% of the power. This huge reduction in energy consumption can enable consumers to save hundreds of dollars over the life of each light.
The Value of Opus LED Lighting
An Opus LED Light fixture can replace 128 watts 4 lamp T8 light fixture while using only 40 watts. In its 50,000 hour lifetime it will consume about 2000 kilowatt-hours, costing about $240.
During that time, it will never need to be replaced.
The Cost of Fluorescent Lamps
A typical 32 watt T8 fluorescent tube lasts for 15,000 hours before replacement. To match the light output and longevity of a Opus LED panel light, traditional 4 lamp T8 light fixture would consume 5,760 kilowatt-hours, and need to be replaced about 3 times, costing over $691.
It’s a simple story…saving over $600 in electric and re-lamping costs, for every light fixture you replace.
Are your products EnergyStar or DLC certified?
All of our products that require DLC or EnergyStar certification have been certified.
Can LED lights make my life easier?
LED Lighting products are designed to last as long as 50,000 hours. Incredible longevity means that you might never change another light again. 50,000 hours means 50 times the life of a typical incandescent bulb and 4 times the lifetime of an average fluorescent lamp. In fact, if you ran one Opus LED fixture 8 hours per day every day, it would last for almost 20 years. That is enough time for office remodeling.
Reduce Maintenance and Labor
If you are in an office with a fluorescent light system, you probably noticed a colleague, or yourself, not getting enough light in the work space because one fluorescent tube has gone bad; or that the annoyance you get when the technician comes in the replace the lamp. With LED fixtures, you would not experience that annoyance for 50,000 hours. That means no re-lamp expense, labor, or recycles cost for 50,000.
Can your products be used in damp/wet locations such as showers, soffits, etc?
Opus is Ingress Protected IP56; that means it is protected against dust, and temporary flooding. It will work fine in a damp location.
What is efficacy?
Efficacy is a term normally used in cases where the input and output units differ. In lighting, we are concerned with the amount of light (in lumens) produced by a certain amount of electricity (in watts). Efficacy = Lumens Per Watt
Do I have to replace LEDs?
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.
Do you have .ies files for your products?
All .ies files of our products can be found at our information support center of our website. You can also find .ies files in the product page.
Does turning LED lighting on and off reduce lifetime?
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.
How do you evaluate LED products?
Lumen output is only part of the story and can be misleading. To fully evaluate an LED product one needs to review the overall system efficiency, optical control, thermal management of the LEDs, and know at what point in time the fixture will reach 30 percent lumen depreciation.
Products with good optical efficiency and thermal management will be able to deliver more lumens, on average, than traditional HID products.
As the Department of Energy concluded in its Solid-State Lighting Commercial Product Testing Program: “Until the field of SSL technologies and supporting knowledge matures, any claims regarding performance of SSL luminaires should be based on overall luminaire efficacy (i.e., from testing of the entire luminaire, including LEDs, drivers, heat sinks, optical lenses and housing), to avoid misleading buyers and causing long-term damage to the SSL market.”

What does “Lifetime 50,000 hours” mean?
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. Cree tested our LED lamps 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.
What is an LED?
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.

What is CRI, and why is it important?
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.
Why are LEDs considered a GREEN technology?
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.
Why is the life span of an LED measured as lumen depreciation?
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.
Do they come with a warranty?
Yes, The LED panels come with a 5 year warranty with no physical damage, while the T5HO ballast comes with a 2 year warranty. In addition, we warranty their arrival to you in working condition and not damaged.
How do I wire and mount these?
It is always recommended for these to be installed by a licensed and experienced electrician. The LED panels and Fluorescent highbays come with a hanging chain for suspension mount, while the LED’s can also be surface or recessed mounted.
How does the warranty work?
We have very few problems, but in the event of an issue we troubleshoot the problem over the phone so that we can get the problem corrected the first time. In the event of a faulty ballast or LED light fixture, we ship a new one to you and pay for the defect to be returned. Completely hassle free!
Where are these high bay linear fluorescent light fixtures typically installed?
These high bay lights are installed in a variety of locations. Manufacturing environments, warehouses, indoor baseball batting cage and training facilities, gymnasiums, pole barns, metal buildings, woodworking shops, and any other area where you need alot of light.
Will these lights work in cold environments?
The ballasts in these high bay linear fluorescent lights are rated to zero degrees. We are located in Canada and have some pretty cold winters and have not experienced any issues with these lights in any of our unheated/heated warehouses.
What are the key features of the T5HO?
Quick Ballast Access: The ballast can easily be accessed via the Access panel in the back.
Dual Ballast: To help increase efficiency by reducing the load on each ballast
Side Rails: The reflectors are protected by steel side rails, which help protect the critical dimensions of the optics during shipping and installation.
Tube protection: Wire guards or lenses are available for factory or field installation.
Can I get wire guards factory-installed on the T5HO?
Yes, wireguards now can be factory-installed onto any of the T5HO fixtures. The wire guards will be installed directly to the side rails unless the T5HO is lensed – in which case the wireguard will be mounted directly to the lens doorframe.
What reflector options will I have?
There are 2 reflector options:
1. Miro4: produced with specular 95% reflective aluminum with 3-5% uplight typical.
2. 320G: produced with specular 85% reflective aluminum with 3-5% uplight typical.
