All of my lamps are made using a 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 100,000 hour life span and uses less than 1 watt of power (sixty of these lamps use less power than one 60 watt bulb). ~The combination of the crushed glass crystal coating and the specular LED light source produce an unearthly sparkling glow that illuminates the bottle intensely. ~ This lamp will cost pennies a year to operate and if left on 24/7 will last over 11 years. ~ Bottle is permanently bonded to the base that compliments the bottle. This is the 750 ml size bottle, height is12 inches
