The Column Floor Lamp can illuminate any room with even lighting. A beautiful frosted glass shade diffuses bright ambient light. A patented 300-watt double socket construction allows for two crisscrossed sockets, each holding on/off 150-watt incandescent or LED bulbs which provides approximately 3 times more light than a typical floor lamp. The metallic finish is complemented with accents on a chunky pole that gives the lamp a bold presence in a room. A simple high/low rotary switch is located on the pole to adjust the brightness. This lamp has a cord and is smart outlet compatible. Use incandescent bulbs up to 150 watts or dimmable LED bulbs (DO NOT USE: 3-way bulbs or CFLs). 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 (the high setting will always have no flicker). A dimmable LED will minimize the low-setting flicker, but may still occur. Bulbs are not included.
