When screwed in for the first time, it is only half lit. The part closest to the nest is fully lit. But the part at the end is only partially lit. So there is very little light. Apparently only half will light properly because the temperature difference between the two ends is obvious. Tried on 3 different devices, same problem. And I have used other CF bulbs of the same general type and wattage and they give much more light. Don't buy a Sunlite. This problem occurs with both the original lamp that was sent to me and with a replacement lamp. Garbage.
