Philips is known for its quality lighting. The Philips PL-S CFL bulb therefore has the same high quality that you would expect from Philips. Due to the use of the, by Philips invented, bridge technology, the light efficiency is much higher compared to light bulbs with curved technology. The PL-S CFL bulbs are available in multiple colour temperatures and the 4-pin PL-S bulbs are even dimmable. The PL-S is, due to the 2-pin and 4-pin base, very easy to plug-in. Are you looking for a more durable version of the PL-S CFL bulb? There are also PL-S LED CFL bulbs available!
