I will not compare these bulbs to the new curly bulbs as there is little to compare. These bulbs emit light at a satisfactory rate and even now cost less than other alternatives. They keep a satisfactory time and work well for our needs. If a cell burns out, it's very easy to take it out of its socket and throw it in the trash without worrying about EPA hitting me for not having a way to properly dispose of the alternative bulb. To be honest we have about 6 other bulbs out there in our use that the number of lumens they produce doesn't really matter to us and they last a long time. We don't have them at home and although we tried, we ran into some issues that prevented us from using them.
