We decided to put the SS550 to the test and see how well it performs in different growing operations.
In this review, we’ll talk about what we liked and didn’t like about this grow light so that you can make an informed decision when it comes time to buy.
The Strong Suit— Programmable Spectrum Control
As the name suggests, programmable spectrum control is the main selling point of the SolarSystem line of LED grow lights from California Lightworks.
This feature allows growers to select and adjust the light output spectrum of their fixtures to match the specific needs of their plants at different stages of growth.
For example, during vegetative growth, plants generally prefer a bluer light spectrum that promotes compact growth and strong stem development.
During flowering, however, they typically prefer a redder light spectrum that encourages bud development and heavy yields.
By being able to adjust the spectrum output of their grow lights, growers using SolarSystem LEDs can optimize plant growth and yield potential throughout the entire life cycle.
In addition to programmable spectrum control, SolarSystem LEDs also offer several other features that make them an attractive option for growers looking to switch to LED lighting.
These include high efficiency (2.5 umol/J), low heat output, long lifespan (50,000+ hours), and easy installation/operation.
