~ I coat the inside of my bottles with tiny glass crystals that make it sparkle and glow when the LED shines on it. Bottles without the glass crystals do not have a sparkle or glow and they look terrible.This San Pellegrino 750ml Spring Water Bottle Lamp is the large 24oz bottle, height is 12 inches. ~This is no ordinary bottle lamp! All of my lamps are made using a painstaking,time consuming process that has tiny "diamond like" glass crystals applied to the inside surface of the bottle and uses new wide angle LED technology (to spread light throughout the bottle without using "string lights"). ~The green LED light produces almost no heat, has over a 50,000 hour life span and uses less than 1 watt of power ~The combination of the crushed glass crystal coating and the specular LED light source produce an unearthly sparkling glow that illuminates the bottle intensely.
