Typical fixture sizes include 1x4 troffers, 2x2 troffers, and 2x4 troffers. This type of interior lighting is located in a range of building types and workplace usage, and commonly used to provide illumination for commercial lighting, industrial lighting, retail lighting, warehouse lighting, and classroom lighting applications.
Below are a few image examples of troffer lighting applications. The below photos are by no means representative of all the types of 1x4 troffer, 2x2 troffer, and 2x4 troffer applications, they are just a quick visual sample.
Most existing Recessed Troffer lighting applications utilize fluorescent lamps such as T12 bulbs, T8 bulbs, and on occasion T5 bulbs.
LED Recessed Lighting, such as 1x4 LED troffers, 2x2 LED Troffers, and 2x4 LED Troffers provide a range of benefits over conventional fluorescent recessed troffer lighting applications. As we mentioned in previous educational material, the way LEDs operate is very different than conventional lighting, and thus there are specific performance elements that operational advantages. The quality of a LED Troffer is very dependent on the manufacturer producing them. Commercial LED lighting, Industrial LED Lighting, LED warehouse lighting, LED Office lighting, and LED retail lighting can all result in significant benefits to end users.
2x4 LED Troffers, 2x2 LED Troffers, and 1x4 LED Troffers range in wattage from 22 watts to 50 watts, resulting in a 40% to 60% reduction in energy consumption over fluorescent light fixtures. The LED Light Fixture wattage range is so dramatic due to the need and ability to adapt to the many different applications that exist for conventional recessed troffer applications. By using a LED troffer 2x4, it is possible to save $81 per fixture, per year in electricity costs.
As we discussed earlier, the way LEDs generate light and progress through their functional life results in a much longer operating life compared to a conventional fluorescent light. LED troffer lifetimes range from 50,000 to 150,000 hours and can have up to a 10 year manufacturer warranty. Since LED Light Fixtures are not negatively affected by frequent on/off cycles, maintenance costs are reduced in those environments when the LED ceiling lights are used. For a typical warehouse lighting or commercial lighting space, end users can expect to realize up to $2,952 in maintenance cost savings over the course of 3 years.
Moving on to the way LEDs distribute light, we can see how LED troffer fixtures provide significant performance improvements over fluorescent light fixtures, including but not limited to a more even distribution of foot candles. LED troffers are available in a wide range of CCTs, which provides end users the ability to select a specific aesthetic look of a given space, and a high CRI (color rendering index) ensures that anyone working under the LED Lighting can clearly see what they are working on. Another benefit of LED troffers is the ability of the fixtures to dim. This development is a drastic change for end users, as they are now able to change the operating conditions after their LED retrofit and adapt to the usage needs of individual rooms or spaces quickly without compromising the functionality of the LED lights themselves.
