Will trade my 7 month old 8 x 39 wifi powermodule for your 6 x 39 or 4 x 39 wifi powermodule. If you have a 6 x 39 i will trade straight up. I ship mine to you and you ship yours to me. If you have a 4 x 39 I will need $75 boot money. I am only interested in factory wifi powermodules. I am not interested in any other fixture.
