Inda-Gro How it Works!
The Inda-Gro Light is an Electromagnetic Fluorescent Discharge Light (EFDL). A good EFDL lamp is like a fluorescent lamp on steroids, with no electrodes to wear out quickly, based on Nicola Tesla's well-known principles, light can be generated via a gas discharge through electromagnetic induction.
This EFDL Lamp is a light source that combines the principle of electric-magnetic induction and gas discharging. Since there's no electrode and filament inside the lamp it is also known as the "Electrode-less" lamp.
The life time of Electromagnetic Induction Lamp can be up to 100,000 hours, which is 100 times of incandescent lamp, 5-15 times of HID (High Intensity Discharge) lamp and 5-10 times of CFL (Compact Fluorescent Lamp).
Electromagnetic transformers, which consists of rings with metal coils, create an electromagnetic field around a glass tube which contains a gas, using a high or low frequency that is generated by an electronic ballast. The discharge path, induced by the coils, forms a closed loop causing acceleration or avalanche of free electrons, which collide with a solid amalgam of mercury atoms which excite the electrons. As the excited electrons from these atoms fall back from this higher energy state to a lower stable level, a plasma state, as they emit ultraviolet radiation. The UV radiation is converted to visible light as it passes through a unique phosphor coating on the surface of the tube, which in this instance produces a strong full spectrum response. All but 2-3% of the UV is converted, the small remaining UV is beneficial to plant growth. The unusual shape of an induction lamp maximizes the efficiency of the fields that are generated. Inda-Gro use only rectangular tubes for a better coverage match for horitculture.
