Do not buy them. The base is irregularly shaped and does not fit into the outlet. It sucks to buy these Chinese non-brands and that's a failure. I bought a similar brand last year that worked fine but they were no longer available.
Pros
EXCELLENT AND SAFE LIGHT OUTPUT: High quality eco-halogen. Wide beam angle of 360°. 2700K warm/soft white (yellowish), CRI 100, mercury-free. Immediate activation.
