Beghelli introduce to the market the innovative technology based on pure Sapphire filament.

Wide range of LED filament lamps entirely of glass with familiar design that provides a very high efficiency. With this new wide range of energy saving ZafiroLed bulbs, Beghelli offer the best of LED technology keeping the look of classic incandescent lamps with better performance.
Beghelli ZafiroLed lamps incorporate an evolutionary new lay of pure sapphire substrate instead of copper or glass commonly used for this kind of lamps. Sapphire filament has excellent thermal conductivity, it resists to high pressure and aggressive chemical impacts. The hardness of Sapphire is only after diamond in all crystal materials thus the strength is quite great. Sapphire filament has excellent thermal conductivity because it can even resist 2050 degree high temperature, whereas copper resist only 1083 degree, granting a longer life to the lamp. The combination of excellent thermal conductivity and high resistant to heat, together with the mixture of gas inside the bulb provide high performance and reliability.
