Choosing the Right LED Light Tube
Linear LEDs are lighting fixtures that are designed to be set up in a linear fashion. Because of this, linear lights can be used in a variety of areas including offices, restaurants, retail stores, lobbies, schools, hospitals, production lighting, traffic zones and corridors, grocery stores, industry lighting, and other general uses. While the applications for an LED T8 light tube is limitless, it is important to know exactly what type of light you need based on these factors.
With new light bulbs, 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, LEDs (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 asses 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.
The standard LED light tube fixture comes in 2 ft. and 4 ft. (and on occasion, longer) options, providing a number of different choices for sizing. The size of the linear light you would need is determined by the area in which you are working in. Make sure to measure the workspace accurately so that you can buy the accordingly sized light.
When a fixture is 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.
