It’s What Plants Reach For!



Inda-Gro Induction Grow Lights provide your plants the best horticultural lighting for explosive growth and high yields from a single lamp source that is used for the entire vegetative through flowering cycle while saving between 60-70% of the energy consumed by traditional lamp technologies.

How does EFDL benefit Plant Growth?

Inda-Gro Induction lamps are a type of High Output Fluorescent lamp that are known as Electrode less Fluorescent Discharge Lamps or EFDL for short. Unlike conventional lamps which require screw in sockets or pins to power up the lamps, the EFDL induction lamp does not rely on a socket or pin connection to power the lamp. Instead EFDL efficiencies derive from being powered by a high frequency electromagnetic field. Without the use of pins, sockets or ballasts to operate the lamp, more energy is converted into usable plant light and not wasted due to the high temperatures and escaping gas inefficiencies that is inherent of lamps requiring electrodes.

First introduced and patented in 1891 by Nikola Tesla, induction lamps, while expensive, were always prized for their; High Lumens per watt, Low Operating Temperatures, Crisp Color, Long Lamp Life and Low Lumen Depreciation over their entire life. Inda-Gro’s EFDL Bi-Spectrum lamps have affordably combined the proven benefits of this technology with the unique spectral requirements so essential for robust plant development.

Inda-Gro’s custom horticultural phosphor blends are designed to be used as a primary grow light from vegetative on through flowering and budding stages. Moreover our fixtures replace the need for higher wattage fixtures and the lamp changes normally associated with different growth periods.

When comparing other types of energy efficient grow lamps, such as LED, your investment in an Inda-Gro fixture will prove to be the longest lasting, most energy efficient, zero stress, zero maintenance grow lamp you will ever own.

Let There be Light!

We can all thank Thomas Edison, who in 1879 patented the incandescent lamp which provided the world with the first mass production light bulb that would eventually replace the use of kerosene oil lamps.

The Edison lamps created light by use of internal electrodes, or wires, that burn a filament inside the glass bulb enclosure and lasted only an average of 1,200 hours before requiring replacement. This worked out to a lamp replacement every 4 months if burned just 10 hours a night. Edison lamps while not long lasting or energy efficient propelled Edison’s lamp business to become a huge commercial success. Early Edison investors, such as Vanderbilt and J.P. Morgan, realized extraordinary continuous profits from supplying the world with the purchase and resupply of Edison lamps.

While today’s internal electrode type lamps have improved from the original Edison lamp, most (up to 90%) of the energy consumed continues to be wasted as heat and escaping gas from the lamp. These inefficiencies are attributable to lamp depreciation through lowered lumen output and shortened lamp life with lamp replacement being the only accepted remedy. Lamp replacement sales continue to drive enormous industry profits.

What Tesla knew then, Growers know now

Beginning with the proven efficiencies of low wattage and high output EFDL technology, Inda-Gro lamps combine a blend of rare earth phosphors to supply the proper spectrums of our plants overall lighting needs.
