This Dark Oak Illuminous 27" Double Bath Vanity Topmount vessel is a most unique creation. It features a Translucent Yellow Honey Onyx Countertop with LED light for the perfect mood every time. LEDs (Light Emitting Diodes) are used to create a mood lighted honey onyx stone. As the light from the LEDs pass through the translucent stone vanity counter top, they illuminates the honey onyx creating a stunning visual effect. As the light moves out to the surrounding room, it retains many of the colors found within the stone. This creates a gentle, calming and romantic mood lighting effect. LEDs are a low voltage energy efficient way of lighting this piece. The attributes to LED lighting are low energy consumption with no UV radiation, using little heat and the lights are very durable. They feature no filament that could be damaged due to shock or vibration and gives you over 20,000 hours of use prior to replacing.
