LED Bulb MR16 Base, Equivalent to 50W Halogen (5W) Color Temperature: 3000K, 450lm, 12V LED Spotlight, Set of 10 + Halogen Sockets and Connectors I planned to use these for DIY projects, but I'm selling them because I won't be using them. The connectors are no longer sold on Amazon, so I don't have detailed information, but they should fit the bulbs. Also, please note that there was some minor soiling from the time of purchase. I will ship them in simple packaging.
