MR11 and MR16 lamp housing standards

[erkkimerkki]

Hello!

Does anyone know, what are the specifications for those two standards? I am planning to do diy-housings, but I try to make them so close to MR16 specs I can.... If I just find the specs. that is :tinfoil:

MR11 is around 35mm dia & MR16 is around 50mm dia.
