<p>An adjustable light fitting, such as an angle-poise lamp, includes a support arm (2, 4) having two parallel members (30, 31) which slide longitudinally relative to each other during adjustment of the arm to change the position of a lamp holder (6). The two members, and hence the arm, are retained in the adjusted position due to an elongate magnet (38) fixed to one member and into contact with which the other member is urged by the magnetic attraction.</p> |
