Nobody needs introduction and history of Philips, so straight to the thing. This thing is basically worth smoldering through money. I obtained a 18 watt CFL two years earlier for around 400 rupees(dont recall the right cost). CFL gives clear and unbelievable white light over a long partition. It is satisfactory to help up my 5m x 4m room nicely.It eats up less essentialness than my tube so I use this CFL for always. I have been using this for quite a while and it is working smoot, so its solid. It goes with a two year ensure also, that make you can breathe a sigh of relief. So I would suggest in case you ever consider acquiring CFL you can go for this one. It justifies smoldering through money to value a CLEAR and BRIGHT light.
