    GU24 Pin Standard Size

    Hello,

    I work for an LED lighting company and am currently designing a lamp module for use in a GU24 socket, like those used by CFLs. I was wondering if anyone knew if there was a standard spec for the dimensions of GU24 pins and the shelf that they come out of; the relevant CSA/UL standard just gives the 24mm spacing, and all I could find online was the 5mm large / 3.4mm small diameters of the pins. Any help would be greatly appreciated!

    See the following documents - there does not appear to be an ANSI of other standard, yet.

    Thanks Kelly!

    These are helpful, but I was hoping to find something with those height dimensions and the shelf that's on the lamp itself. I'll grab a couple existing GU24 lamps and take measurements, then post a quick drawing on here with the ranges.
