Very flexible. Gooseneck stays exactly where you place it. The head lets you either extend the bulb or retract it into the head.

These lights are great, but the 150W bulbs that were recommended are like outside flood lights and are not suitable for highlighting art. We plan to get a smaller 60W bulb instead.

This halogen line voltage flexible light fixture was purchased for a very specific application and works well with a PAR-16 spot lamp (60 watts). DO NOT purchase the recommended PAR-38 flood lamp because it is too heavy for the 4' fixture (and probably also too heavy for the 2' fixture). The PAR-38 is also 5" in diameter and totally inappropriate looks-wise for the fixture's design. The PAR-16 spot lamps (45w - 65w) that are only 2" in diameter can fit entirely within the fixture for a more dramatic effect. The locking slide mechanism enables this ability. The lamps shown in the catalog photo are NOT the "recommended" PAR-38s and are obviously smaller and look to be about 3" in diameter. An email has been sent to WAC Lighting with my complaint about this lamp discrepancy. Unless you know your lamps precisely, it is better to purchase the fixtures without lamps and to then buy them later.

The fixtures were much nicer than I had expected and their flexibility gave me wide latitude in illumnating a challenging piece of art.
