I have had them for two years now. They are great! As my car is triple black, the standard bulbs barely lit the interior! I need light! They replaced the standard bulbs perfectly. The drivers side footwell bulb burned out within a year. I e-mailed the place where I bought them (can't remember where) and they sent me two new ones right away! When I removed the bulb, I noticed that the plastic lens was melted directly under the bulb. I was a little worried so I used a one inch hole cutter and drilled out the melted spot. Now I have more light on the floor and do not worry about the heat. I do have to say though that I usually keep the overhead lights off unless I have people in the car, so I don't know if those would have the same problem.
