Replacement lamp for Samsung DLP Projection TV Model HL-R4266W. May fit other models in the same family (the 42 is because the TV was 42"), but I can't guarantee it - make sure this fits your TV before bidding.
This was purchased as a replacement for my original lamp, and didn't get a lot of use before I got a new TV. Hours are low, but I don't know exactly how many have been put on the light. It was working and bright before I took it out of the TV. Lamp is being sold as-is and no returns are accepted.
