This project was the first time that we have used the new T8 LED lighting tubes. We have been skeptical of these in the past, based on their price and relatively minor improvements over high efficiency T8 fluorescent lights. However, in this situation the lights in question were over 45 feet in the air and the only way to get to the lights was by building an expensive scaffolding. The T8 light tubes that we purchased were rated at 60,000 hours, which is significantly longer than even the T8 extra long life bulbs.
Below is the picture of the lights before any retrofit was done. The height of the lights made maintenance very difficult. Maintenance on the bulbs had not been done in several years due to the cost of the scaffolding build.
Even though the LED tubes were significantly more expensive than just a simple T12 to T8 lighting retrofit, we felt that in this case the extra cost of the LED tubes was justified.

These lights were at a location that was simply not accessable by use of a scissor lift. The only way to get to the lights was through scaffolding build, at a cost of thousands of dollars, and a large disruption to clients.
Before the lighting retrofit there were no lighting controls on these lights and they ran 24/7. We have now added a lighting control that turns off the lights in evenings and weekends. This will significantly cutdown the overall run time of the lights.
With the LED tube lights and the addition of the time clock controlling the lighting hours we believe it will be several years before the scaffolding build needs to be done again.
