This is a basic wall lamp, I created for an open request. I am not sure if it is the one ;)
Kinda late, maybe someone else will need this: just hit space and search for Remove Doubles it'll decrease polies substantialy
Just lower the subsurf modifier value and I think it will help you. You can find it in the Modifiers panel. The rest I really have no idea.
Ah this is totally perfect! (I am not the requester but am working on a 3d sci fi platformer) A problem is it is comprised of a large amount of faces (I am significantly amateur in modeling) is there a simple way or a link to a tutorial to lower the poly count, or to bake or something. I am following this and hope someone replies.
