The Sylvania Lynx-SE energy saving bulbs are energy-efficient and can all be dimmed with a suitable ballast. The CFL bulbs by Sylvania consist of a good color rendering (Ra = 85) with a choice of very warm white (827), warm white (830) and cool white (840) light colours. The discrete energy saving light bulbs have an average lifespan of 10.000 burning hours. Because the lifespan is so long, the Sylvania Lynx-SE CFL bulbs do not have to be replaced as often.
