I've looked at 100's of pics of viv's and so many of them have these track looking light things, that i assume you can possibly position in the direction you'd like.......i guess i'm not quite sure what to search for b/c I can't find single things like that to screw into the wood in the viv (ceiling). I currently have a dome but i would rather just have the light.....also can anyone assist with how to install glass sliding doors??? or send me to some link that can? Thank you!
