I tried this in my dining hall.
1. I changed all 4 E27 sockets to LED bulb at the same time (all bulb has same luminance, will undergo same amount of switching on-off and usage time)
2. The 4 LED bulb that I used is - 1 midea, 1 philips, 1 osram, 1 mrDIY with the price range from 11+ to 28+
3. The color is not much differencecomparaing each other, if you are didn't pay very much attention to it.
4. After 6 months usage, all except one is stop functioning. The brand started with o.... (this i get a replacement as it still under warranty)
5. The rest of the LED bulbs still has the same amount of luminance/color comparing each others.
6. The test is still ongoing.

The test is limited by one random LED bulb which may not be representative of the whole product. I can only conclude that the cheaper brand is not worse than the more branded one.
