Programmable Spectrum Control

  • With the SolarSystem Controller, you can automatically adjust each of the three separate light spectrum channels from 0% to 99%. This can be done manually or automatically using the built in timer and calendar.
    • Channel 1 - Red & Deep Red
    • Channel 2 - Natural White View Mode
    • Channel 3 - Blue and Deep Blue
  • A single controller can control a virtually unlimited number of fixtures from a single point or can be separated into zones at minimal cost.
  • Automated programs for sunrise and sunset that mimic nature as well as programs for spring, summer and fall for more natural accruing patterns that improve growth.
  • Variable Dark Period and finishing routines to maximize resin output.
  • Programmable UVB and IR Supplementation will result in a more potent end product.

High Efficiency and Low Maintenance

  • The SolarSystem 550 will produce the same yield as an HPS or MH light with an average of 40% less energy usage. Using the advanced spectrum control system will further increase efficiency and yield compared to old fashion fixed spectrum lighting.
  • The SolarSystem controller can be linked to a light sensor in a greenhouse to maximize wasted energy.
  • CLW LED's are plug and play and very light weight so installation is streamlined. Add that to the advantage of never changing a bulb and you have the industry’s most efficient lighting system.

Highest Yields. Guaranteed.

  • Top of the Line Osram LED's are driven to their maximum power rating using the exclusive active heat management system from California Lightworks. Higher power equals higher yields.
  • Using the adjustable spectrum control to maximize blues and deep blues during the vegetative stage produces lush growth, shorter spacing between nodes and less stretching.
  • Maximizing red and deep reds in bloom to increase yield and resin output.

Best Value. Highest Return On Investment.

  • The Solar System 550 features advanced design and manufacturing that produces a high powered LED fixture at a very reasonable cost.
  • Lower purchase cost, reduced energy usage and the elimination of replacement bulbs matched with higher yields means the best return on investment in the industry.
  • Smart controls for optimal energy usage.

Networking & Integration.

  • The Solar System is an intelligent networking light system that will evolve through software advances without having to upgrade equipment.
  • Advanced lighting parameters can be developed and saved for any type of plants or growing conditions.
  • Additional lighting equipment options can be added to the system including separate fixtures for UVB, infrared or specialized supplemental lighting.
  • The system can be integrated with light sensors daylight harvesting or spectrum specific supplemental lighting in greenhouses.
  • Options are also available for PC, wireless, internet, and smart phone applications

Basic Spectrum Mixes for the SolarSystem 550

The following table are basic spectrum mixes for various growth stages for flowering plants. These spectrum mixes have been determined from 8 years of experience with the California Lightworks grower network, and are supported by various university studies on varying spectrum effects on Plant Morphology.

In general, blue light is essential in vegetative growth and produces lush growth and bushy plants. Red tends to make plants stretch in vegetative growth but is key for high yields in fruit or flowering plants. The SolarSystem 550 allows you to dial in exactly the spectrum mix needed for any phase of growth.

Growth Stage Week Number RED WHITE BLUE
Vegetative Varies* 49 99 99
Pre-Flowering 1 to 2* 74 99 99
Flowering 3 to 5* 99 99 99
Ripen 7 to 8* 80 90 99

*Weeks based on an 8-week flower cycle

Surprised by this light so far

For the price of this light, especially compared to the solar storm 440 I think this will out perform it as well as any other LED I have had so far. Being able to customize the spectrum for a bank of lights and then connecting the controller to another bank of lights in my flower room with a different spectrum is really cool and easy to do. Small, but powerful! Will be buying another one when I can.
