Description : I have an energy-saving light bulb and every time I turn it on, it lasts for about 4 seconds. It is normal? Or is it damaged?
Last Answer : 4 s to full power? It's not long. To save money, of course (some start up to 15-20 s). ;-) Anyway - if it starts up, it's not damaged. If you need a faster reaction, "go back" to ... one somewhere where there is no need for a fast start-up and where it lights up longer ("flashing" does not help).
