T8 LED tubes, also known as TL-D light tubes, are replacers for the often used T8 fluorescent tube. LED tubes are instant fit replacers that have serval advantages compared to conventional lighting. T8 LED tubes have a longer life with a warranty, which ensures you to have lower maintenance costs. LED in general uses way less energy than any other light source, so your energy costs may drop up to 70% when switching to LED. T8 LED tubes have a more logical way of using their energy. Fluorescent tubes emit light in a 360º beam angle and light up unnecessary places like the ceiling. LED tube lighting have a beam angle around 180º, emitting light only downwards, where it is needed.
