Bulb Type
Many modern wave lamps / projectors list “LED Light Source / LED bulb” explicitly., LED bulbs use less power, produce less heat, are energy-efficient, and support features like multiple colours, remote-controlled colour modes, dimming or colour-changing — which are common in wave lamps., Since wave lamps often project colourful light patterns (blues, greens, RGB, etc.), LED gives better control and variety than traditional incandescent bulbs.
