Using the Pablo Bel Occhio Table Lamp is easy. First, find a stable surface to place the lamp if you're using it as a table lamp. If you prefer the pendant style, install it in a proper location. To adjust the light direction, simply touch the lamp and make 360 - degree adjustments as you like. Use the included dimmer to change the brightness according to your mood and needs. When it comes to bulbs, the lamp uses a 75W 120V E26 medium - base white BT15 halogen lamp. If the bulb burns out, replace it with the same type. For maintenance, gently wipe the acrylic sphere and base with a soft, dry cloth. Avoid using abrasive cleaners as they may scratch the surface. Keep the fabric cord away from sharp objects to prevent damage. This lamp is covered by a 30 - day return policy, so if you have any issues, you can return it within this period.
