Some do, er the rise and fall type of fitting over a dining table where when you're er, er having dinner you'd have erm it down to about what not more than twelve inches above the table er so that it lit the table but didn't shine in your eyes, erm some people leave it like that all the time, other people having had a meal lift er it up, erm I think the main thing about the, er adjustable fly and fall is that erm, it's there for, as you want it, if you're trying to find a meal you've lost on the floor well then you pull it down to floor level really.
