I recently purchased various LED's from Ebay (via China). I tried to match up the brightness ratings (lumens) to my current incandescent bulbs. Two problems:
1. The LED's SMDs (surface mounted devices) worked in all of the sockets, however, in many of the light fixtures, they would get excessively hot (even for an LED bulb). Two of them became so hot, they began to smoke from the heat generated! I took them out and shortly thereafter replaced them all with the original incandescent bulbs. Many of the non-smokers were brown and probably on the verge of smoking. I realize they may get hot, but something was wrong if they get so hot they smoke. I'm not sure if they were defective or this would have been expected with the high lumen ratings. Buyer beware.
2. After putting LED's in all my fixtures, I felt that the light seemed very "unnatural" - almost too white, and a creepy "washed-out" feeling to the color of objects under the LED lights.
Too each their own, but beware of the Chinese made LED's.
