This is the light that I use in my utility closet turned darkroom. Works great!

I'm in the same boat as you were. 90% of my life is in my bedroom. I'm still living at home, so everything I own except for my tea and one laptop is in my bedroom. I have one lamp and one overhead light in my bedroom, the overhead is a regular 100watt bulb and the lamp uses this 25 watt red bulb. I only use it after dark and only for reading. Being 25 watts, it isn't too bright but allows me just enough light to see my way around if I have to find something.

There are ways to make developer rather cheaply. http://www.instructables.com/id/Caffenol-C-Coffee-Film-Developer/

And this would add to the DIY aspect of something like this.

And a Darkroom Bulb is $5
