- Replacement Lighting
The older style T12 fluorescent lighting systems are obsolete but they are still widely used. However, if you are still using the T12 bulbs you will be looking for replacement lighting soon. In 2009 the Department of Energy instituted rules that would eliminate most of the T12 lamps by July 14, 2012. That date has now come and gone and now it’s time to find some replacement lighting so let’s go over some of your options.
T8 lamps have a number of benefits over the older, T12 lamps. One of the biggest benefits is that they are far more energy efficient and you can save as much as 50% in energy and operating costs with T8 lamps compared to T12 lamps. In addition to being more energy efficient, T8 lamps also have a longer lifespan and may last as much as 10,000 hours longer than T12 lamps. So in addition to better energy efficiency you will also have reduced maintenance costs because you won’t have to pay someone to spend time changing light bulbs.
T8 lamps even provide a better quality of light than T12 lamps. Light quality is measured on the “color rendering index” which measures the quality of light on a scale from 0 to 100. T8 lamps are rated at 82 or higher in most cases and T12 lamps are normally in the 60 to 70 CRI range.
T5 lamps are smaller in diameter than T8 lamps. The “T” refers to the shape of the lamps which is tubular and the number following the T refers to the diameter measured in 8ths of an inch. A T8 bulb is 8/8 inch or one inch in diameter. A T5 bulb has a diameter of 5/8 inch.
T5 lamps put out very bright light, brighter than that of T12 and T8 lamps. They may be too bright for small areas where the light source is directly visible but they may be ideal for fixtures that are compact and provide indirect light. T8 and T5 lamps both produce very good quality light and both have very low lumen degridation (the loss of light output as a bulb ages) but T5 lamps have a shorter lifespan than T8 lamps by about 15%.
Replacement lighting is something you may need to think about sooner or later.
