2.4.6 Replacement of fluorescent tubes by others with less diameter

2.4.6 Replacement of fluorescent tubes by others with less diameter

Description

The most commonly used fluorescent lamps today are the T8 (ø 26 mm). However, the T5, (ø 16 mm) which only work with auxiliary electronic equipment, have been developed. This, along with its minor diameter provides a high luminous efficiency, which can reach up to 104 lm/W.

Benefits

  • T5 tubes energy consumption about 35-45% less than T8

  • The start-up is almost instantaneous and without flicker

  • The standard average lifespan of T5 tube is three times more than traditional T8

  • T5 tubes have a lower content of mercury (4 times less)

  • Adapters do not require lamp change and the transformation is performed as if it were a simple tube change

Limitations

  • Cause Glare

Economic assessment

Installation cost: high. T5 tube is around 50-60% more expensive than traditional T8.

Payback: between 3-5 years.
