 If your company is in need of a lighting retrofit, and you're not sure about whether to install LED or T5 technology, here's a rundown of their differences to help you make an informed decision. Although LED might be more appealing to the eye at first, T5 technology is likely going to be a better option for your facility, warehouse or other large commercial workspace.

Most of our commercial customers purchase T5 fluorescent lighting over LED fixtures because fluorescent technology provide a more cost effective solution for most companies. The upfront cost for purchasing LED lighting is substantial when compared to the upfront costs associated with fluorescent fixtures. In fact LED fixtures cost upwards of three times as much as fluorescent lighting fixtures, adding much more to the price of a lighting retrofit. In addition to the fixtures, LED lamps cost almost 24 times that of T5 bulbs, and LED fixtures also put out more heat than T5 bulbs, which can increase your facility's cooling costs substantially. When you're comparing costs between these technologies, you must consider each technology's source cost, that is, how much money it costs per 1,000 lm ( a measure of light intensity). According to a recent study performed by the Institute of Electrical Engineers, T5 bulbs performed at a source cost of about $3 per 1,000 lm, while a similar LED bulb cost more than $70 per 1,000 lm. But what about the quality of light between the two lighting sources?

There are numerous studies showing that when you provide better lighting quality in your company, worker productivity increases substantially. When you compare T5 lighting with LED, T5 does better in the coloring rendering index than LED. What's that mean?

T5 high bay lighting, for instance, produces a higher quality of light because it ranks high on the scale that measures how closely artificial light mimics natural light. The index examines a bulb's ability to reveal color variations on a scale from 0 to 100. On the index, T5 measures 85 and LED measures approximately 70 – meaning, the quality of light T5 lighting produces is significantly greater than LED.
