Intelligent, Value-Based Research & Development
A Grow Light's Efficacy (ability to achieve a desired result) is a culmination of how well all the parts work together as a whole. At Hydro Grow we prioritize our R&D on aspects that have the greatest impact on results, such as absorbable light wavelengths and optimized spectral ratios.
All secondary contributors to performance such as driver type, driver brand, driver efficiency, LED package, LED chip size, LED Brand and LED Bins are chosen based on a cost to performance ratio. A component must offer a comparable increase in performance to it's cost to be used in our LED Grow Lights. This ensures you the highest performance per watt per dollar spent.
Developing the Penetrator XB Series
A New Decade of Horticultural Dominance
In a 2019 online survey we asked growers what they wanted from a LED Grow Light. The overwhelming response was simple:
-
Low Cost (Under $2/watt)
-
At Least 2.5 µmol/Joule Efficiency
-
External Drivers that can Operate Outside Your Room
-
A Square Panel for Square Dispersion
-
Evenly Spread PPFD over Target Coverage Area
-
A Dimmable Driver Option
Penetrator XB was developed specifically to answer these requests with the highest quality and performance.


Step 1: Choosing the Right LEDs
There are many factors that contribute to the overall output and efficiency of a LED:
-
LED Package (SMD, High Power, COB)
-
Optical Lens
-
LED Chip Size
-
LED Chip Positioning
-
LED BINs (Voltage, Brightness)
-
LED Brand
-
Drive Current
Step 2: Optimizing Performance
The primary factors that determine the efficacy (yield/watt) of a LED Grow Light:
-
Light Wavelengths
-
Spectral Ratios (quantum balancing)
-
LED Output (µmol/Joule)
-
Optical Lensing
-
LED Spacing
-
Operating Temperature
-
Driver Efficiency
Step 3: Reducing Overall Costs
The primary factors that determine the final cost per watt of a LED Light:
-
Driver Brand
-
# of LEDs per PCB
-
# of LEDs per Driver
-
LED Brand
-
LED Spectrum
-
Drive Current
-
Heatsink Requirements
