Bright lights and straightforward design, the Aries floor lamp provides the equivalent of 300 watts of incandescent illumination in a single package. The black pole body holds a white acrylic bowl that diffuses the light from two 150 Watt incandescent or equivalent CFL bulbs. Use incandescent bulbs up to 150W or dimmable led bulbs (DO NOT USE: 3-way bulbs or CFL's). We recommend using incandescent bulbs for best results achieving both settings of 50% brightness and 100% brightness with no flicker. When using LED bulbs, it is common to see some flicker on the low setting (high setting will always have no flicker). A dimmable LED will minimize the low setting flicker, but may still occur.
