MR16 6500K 5.5W 360-Lumen 30x5050 SMD LED White Light Bulb (12V)

Pros: A good kind of cool white, not irritatingly blue as some other lights.
Good price per lumen.

Cons: DC only (no rectifier inside). Very dim and/or flickering on AC.
Glass body (potentially brittle).

Other: Use it if you have DC power supply in your system, or fit a rectifier after the transformer. The bulb is polarized - if it doesn't work, plug it the other way.

Pros: The MR16 LED White Light Bulb 12v has a good intensity of light, perfect consumption with it's 5,5 KW and fits perfectly in my dinner room.

Cons: Unfortunately the bulb blinks excessively, I leave it on for hours and the blinking didn't dissapear. Bad white color for home, excessive blue color on the light.

Other: For home I try another bulb from DX soon with less blinking (I hope) and another color more calid.
