Robin,
I have installed a variety of lighting in my dome to suit various requirements.
1. I use a halogen desk light when I need lots of light for working.
2. I have a white and a red luxeon LED at the top of the dome that I can use to help visitors assimilate to their surroundings. I use these (white first, then red second) to point out basic stuff like where the EP and focuser are, and of course, what not to bump.
3. I bought three 12V wall-mounting white LED lights from Bunnings, and modified them by adding four red LEDs (alongside the existing four white LEDs) and a separate switch wire. The three of them are spaced around the observing floor walls about 600 mm above the floor. The three fittings are wired in parallel, and the red and white lights are separately dimmable. I typically start observing with just the red, and dim them further as my eyes adjust and I search for fainter objects.
4. Like Rally, I have also used a few short lengths of the surface-mount self adhesive red LED strips. One is under my wedge which throws some light on whatever is in the 'cubbyhole'. The other strips are under the handrail on the balustrade. These strips are also dimmable.
I also follow Greg's practice of keeping the floor clear so I can move around confidently. Occasionally I bump into the observing chair since it doesn't stay put.
