Not so long ago led grow lights arrived on the market, low yields and small fruits were the cry from the general growing community but nowadays the humble led grow light has started a growing renaissance with large yields and large fruits easily achievable.
The new led grow lights on the market now offer comparable results to High Pressure Sodium lighting but at a fraction of the running costs of Sodium , so how has led grow light technology evolved to now provide a led grow light to rival Hps in both terms of yield and fruit size. The development of high power led diodes and advanced heat dissipation systems now allow the led diodes to run at higher voltages than ever before, the newest led grow lights now come fitted with either double optical lens or triple optical lens which both intensify the light and also provide the perfect light dispersion pattern suitable for explosive growth in both vegetative and bloom cycles of plant growth.
These new led grow lights now have the power to rival the light output of Hps however the introduction of specialised wavelengths and ratios combined with the high power led diodes are what makes the new led grow lights so effective. The first grow lights came with a limited spectrum namely Blue, Red and occasionally Orange, the new wavelengths and ratios available now cover the entire spectrum and include Ultra Violet, Blue, Red, Green,Yellow,Orange, Infra Red, 2700K-7000K white.
These range of wavelengths can now be tuned into very specific ratios to provide increased yields and large fruits, the ability to tailor the individual wavelengths in the ratios allow complete control over the grow lights performance which enables the new led grow lights to be tailored exactly to the growers requirements such as higher yield or increased flavour etc.
These two important areas of the led grow light have transformed the led grow light industry, further improvements in led diode wavelength tuning and optical lens technology will provide very fine tolerances in the led wavelengths. The led diodes used in high quality led grow lights are typically tuned to within 5nm(nanometres) and whilst these provide exceptional results in the future it will be possible to tune the led diodes to the plants exact light reactive points requirements. Lens technology is still in its infancy however already there are double and triple lens available, this area of technology can only improve as time passes however the improvements to be gained are potentially huge.
The humble led grow light is now here to stay and with the further advancements in led technology due over the next few years the future for led grow lights is very bright indeed, High Pressure Sodium lighting has dominated the grow light market for many years however the crown is now slipping and led grow lights might just find the crown is a perfect fit.
