Energy-saving light bulbs

In the past few weeks, three eneregy-saving light bulbs in my house burnt out. These were products from mainland China. I estimate the avearge life-time is about 1 year.

I have used similar products from Philips which last for at least 3 years. I don't think energy-saving bulbs made in China can have a good quality.

If Philips light bulbs cost a few dollar more, it is worth to buy. After all, the product life-time is much longer. This in long term saves me much money.
