Installing a 5 ft post light in my yard. Want mercury vapor but most fixtures are ugly. So I took a incadesent fixture and a hubbell mercury vapor. Switched out ceramic lamp holder in light. Now need to add the transformer. Will it be any problem if I install this in the base of the post? So like adding 5 ft #12 wire between transformer and bulb. The type of post flares out at the bottom so there is plenty room. And do I need to ground the transformer? Post comes in two parts was just going to hang the transformer down into the base with a small piece of cable.
Thanks for any input
