Hi, Thanks for your reply. Why do you choose Philips downlight with Ballast? There is more hardware than downlight without ballast. The cost of the hardware (with and without ballast) is almost the same but the cost of the light tube without ballast is higher. I went to lightings.com.sg and the sales recommend Philips downlight without Ballast. They also show me that downlight without ballast is much energy saver compare to light with ballast. For long term, you pay lesser on electrical bill and the life span is longer than the light tube with ballast. However, my concern is some sales from other lighting shop told me that the tube without ballast blow off easily (regardless any brand of tube) as compare to tube required ballast. They explain that the heat generated from the tube (hinden) in the false ceiling is the main cause of the tube blow. Any comment?
