When choosing a loft light, take the size and height of your loft
into account. In general, a fluorescent strip at the apex of the roof will cast
fewer shadows than a single light bulb.
Electrical circuits for the
floor below should be readily accessible, so fitting a light should be fairly
straightforward. If in doubt, consult a professional. Either fit a conventional
light switch within easy reach of the loft opening, or fit a pull-cord switch
to the ceiling near the loft hatch so that it can be operated from the floor
below. A switch with a neon warning light will tell you if the light has been
left on when the trap door is closed.
