LED Troffer light fixtures are affordable fixtures designed to substitute for T12 and T8 linear fluorescent troffers and deliver lighting for recessed-ceiling applications in schools, offices and hospitals. The LED technology used in these fixtures ensures reliable color consistency. Lighter weight fixture allows for safe, easy installation while long-life LEDs, coupled with high-efficiency drivers, provide extended service life.
Shopping by lumens is more important than shopping by watts when choosing which energy-efficient bulb to purchase. While wattage measures the amount of energy required to light products, lumens measure the amount of light produced. This means that the more lumens the product has, the brighter the light source is. Instead of buying products based on how much energy they consume (watts), consumers should consider how much light they give us (lumens).
Wattage is the measure of the bulb's energy consumption - not how much light it puts out. Energy-efficient bulbs use fewer watts to give off the same amount of brightness (lumens). Because of this, LED fixtures (which have typically low wattages when compared with lumens) not only help reduce energy usage but also lower electric bills.
Color temperature refers to the color appearance of the light that comes from a light source. It's an important performance characteristic to assess when evaluating bulbs because the color temperature creates the mood of the space you are lighting and can thus influence buying behavior or work performance. The apparent color of a light source is measured in Kelvin. The higher the Kelvin temperature, the whiter the light.
When LED troffer light fixtures are DLC Listed (stands for Design Light Consortium) it may qualify for energy rebates by your local utility which can significantly reduce the cost of ownership. The qualified products list is a resource for program administrators, to help them decide which solid state lighting products to include in their energy efficiency promotions.
