LED Advantages over Fluorescent Systems


 

Lifetime

  • Fluorescent Tube Sources last on an average of 15,000 hours in normal use conditions.
  • Our products last on an average of 70,000 hours in normal use conditions

Size

  • Fluorescent Fixtures are cumbersome. Because of inefficiencies and glare issues, fluorescent fixtures are equipped with secondary optics such as reflectors and louvers, which make the profile thicker, are heavier, harder to install and require more depth and ventilation in the ceiling cavity in recessed applications.
  • The low profile of the products allows for installation in tight ceiling cavities and allows for shallower ceiling depths.

Low Voltage Driving

  • Fluorescent Lighting uses high voltage (<2,000V) to generate UV light to excite a phosphor, which, in turn, emits light. Normal office systems will need to provide higher voltages (277V) than the rest of the office appliances for fluorescent lighting.
  • Our products are current driven products. They work on normal household voltages and require no special wiring to accommodate their performance requirements.

Better Color Rendering

  • Fluorescent fixtures have most of their spectral power energy in the green part of the spectrum. This creates unflattering and unnatural appearing light, especially in office environments
  • Our products produce full spectrum light, which is strongest in the blue end of the spectrum. This spectral power distribution allows for the only general lighting product which has been shown to have health benefits.

Health Benefits

  • The fluorescent light generates light through high frequency switching which has been shown to exacerbate the conditions associated with hyperactivity in children. The high amounts of ultraviolet radiation has also been shown when it is the only light source—such as in office lighting applications—to increase the feelings of depression and fatigue in workers.
  • Our’s blue-die based technology has been shown to be the most effective stimulator of the circadian system.  Light that stimulates circadian photo transduction has been shown to alleviate the symptoms of SAD, Alzheimer’s disease, helps to set the body’s “biological clock” in addition to increasing alertness.  It has been cited as a possible aid in reducing the incidence of cancer for women doing shift work and for people working in windowless office environments. 

Disposal

  • Fluorescent bulbs require frequent changing. Because of the presence of mercury in fluorescent lamps, stricter policies have been enacted regarding their disposal. In large office buildings special contractors must be hired to dispose of the bulbs and the bulbs must be taken to specially outfitted incinerators for disposal. This can add significantly to the cost of ownership.
  • Our products last on an average of over 20 years and require no special disposal.

 

Maintenance

  • Fluorescent fixtures because of their complex surface area must be cleaned periodically because of dirt and dust accumulation affecting lumen output. Bulbs break and suffer catastrophic failure regularly, which costs a great deal from a standpoint of regular maintenance.
  • Our products require no maintenance over the lifetime of the bulb.

Better Fixture Efficiency

  • Here is tracking of the energy use and efficiencies of a fluorescent system from bulb to fixture.
  • IN THE BULB: Over 40% of the energy put into fluorescent bulbs is wasted as dissipated heat.
  • The average Lumen output for this 2 by 2 bulb is roughly 2,000 lumens. You put two of these bulbs for a total of 4,000 lumens in the fixture. The average fixture efficiency is roughly 50% to give you a total of 2,000 lumens being emitted by the fixture. All along this supply chain there are inefficiencies: inefficiencies inside the bulb, inefficiencies inside the fixture. The end result is that despite fluorescent’s claims that they emit so many lumens per watt, when you place that bulb in a fixture, your efficiency drops down by 50% on average! In addition, traditional fluorescent fixtures are tube sources and there are additional wastes of 50% of the light directed up into the fixture, where reflectors are needed to try to get this wasted energy into the work plane.
  • We have fixture efficiencies over 90%. Installations using Our products have qualified for energy efficiency programs in the US, where there are some of the most exacting standards.

  • Although the fixtures emit roughly the same lumens, the coefficient of utilization for Our products is much better than fluorescent fixtures. What does that mean? It means that our fixtures are much better at delivering the light to the work plane than fluorescent fixtures.

Cost of light

Lumens and lumens per watt are poor metrics for deciding on a lighting system for office lighting. More important are energy requirements, the effectiveness or ability of the product to do light the task, and, perhaps the most important, the cost of light.

Cost of light is an economic analyzer, which takes into account many factors including: lumens, lamp cost, labor costs, lifetime, power requirements and energy costs. By this metric, Our products are less than half the cost of fluorescent lighting for office applications. That means rates of return that are two-three years and sophisticated lighting that pays for itself well before it needs replacement.
