This weeks grow review features the best performing, best value, and best selling LED grow light that we have seen so far - the SolarSystem 550 which is distributed in Europe by Crazy LEDs, sister company of Dutch Passion. This video shows the SolarSystem 550 being manufactured in USA and explains the features and technical details. Even the heat sink is made in the USA, attention to quality control is impressive, this is a professional quality LED grow light.
Two SolarSystem 550 units were used in a 1.5m x 1.5m grow room to grow some Sour Strawberry cannabis plants and produced great looking results, the grow diary is here. The SolarSystem 550 uses LEDs from Osram who are an LED technology leader and one of the highest quality manufacturers. The LEDs have a lifetime of 50,000+ hours and lose just 10-20% intensity over that time period. Each chip has a maximum power of 5W, but the LED’s run below full power to maximise lifetime. The actual power draw of the SolarSystem 550 on full power is 400W, it replaces a 600W HPS and delivers superior yields whilst using less energy and producing less heat. LED growers don’t need to worry about regular (and costly) HPS bulb changes.
Heat stress is one of the main disadvantages of growing with HPS. LED growers find that excessive grow room heat becomes a thing of the past when they upgrade to LED, this allows the cannabis to grow at more comfortable temperatures with less stress and better quality. HPS growers that routinely struggle with high grow room temperatures in summer see there grow room transformed by professional quality LED growlights.
With two SolarSystem 550’s in the 1.5m x 1.5m grow tent, the grower was able to get superior light intensity than two x 600W HPS, and only use a total 800W of electricity.
By using the optional SolarSystem 550 hand controller the power and spectrum can both be adjusted on the SolarSystem 550. This is very useful for a variety of reasons:
Note that the Osram Deep Red LEDs account for well over half of all the LEDs used in the SolarSystem 550, and they are around 50% efficient. This means that they convert 50% of all electrical energy directly into Deep Red light which is the principal source of energy for cannabis during bloom. Many lower quality chinese-made LED grow lights will use less expensive Deep-Red LEDs with significantly inferior efficiency.
Multiple SolarSystem 550’s can be daisy chained together and all controlled from a single hand controller.
You can still use the SolarSystem 550 growlight without the hand controller, but all the LEDs are automatically set to 100% power.
One of the advantages of the California Lightwork products is that they have been selling LED grow lights to the legal US cannabis industry for the last decade. During this time they have fine tuned and optimised the design reliability, performance and the spectrum output. The large quantities of grow lights being sold to legal US growers give California Lightworks a scale of manufacturing efficiency that few others can match. The SolarSystem 550 is easy to program, and switches itself on and off according to the program instructions, so you don't even need a light timer.
Resin production and bud production on the SolarSystem 550 are as good as any LED growlight we have seen. If you are looking to upgrade your grow room then consider the SolarSystem 550. Its a professional quality light with adjustable power and spectrum, its fully programmable and has lower running costs than an HPS (less energy use, no bulb replacements). But best of all, it grows great quality cannabis. Get yours here.
