What is the true length of a 48" T5

[Coletrickle]

I know they are not 48", so what is the length? I'm wanting to build a housing, but I don't have a bulb yet. What is the length of bulb NOT including the pins.

I need to know how far to space the lamp ends/socket.

Thank you

The length of the bulb end to end without the pins is 45 3/16".
