There is only one light that can be installed on the ceiling, but it is too long to be suitable.

Overall I would like more lighting options. 

Agreed, more lighting options would be great and would solve this issue. 

I agree. More lights. I'm still waiting on half hight stairs even more though. 

I agree, having a whole "2" staircase options is just plain unacceptable. Why are there no other options for those, like ones that use clay and pebbles, or stems and clay, or adobe style, mushroom brick, or ash cement options?

Half stairs, and a set of mushroom stairs that are L shaped but are half stairs at each turn (to compliment the leaf strait stair and acorn 180* curved stair).
