Pros:
Very bright compared to standard lamps. Good shine to the sides and reflectors are used. Temperature is about 6000K. Few shines blue, but not critical.
Cons:
After one year of using half of the leds went out. Now it shines on the level of standard bulbs. I think leds has stopped because of overheating, these lamps have a plastic housing and the leds are not cooled properly.
Other:
As an idea for DIY it's necessary to disassemble these lamps and to solder ballast resistors with more resistance to reduce the LED current. It would be shine only slightly worse, but the heating should be reduced substantially.
Bottomline:
Good lamps, but with an aluminum heat sink it would have been much better!
