Led light are low EMF and low Dirty electricity solution. They are not clean from EMF like incandescent light bulbs but they are much better than CFLs. They do create less heat and consume less electricity than incandescent light bulbs.
These Led light are made in china so not all will work well, but if you are lucky enough to get a good bulk they will work well for years. Up to now (11-2013) I bought 7 of these light bulbs and 5 are working very well for over a year now.
