Spider Farmer has made a name for itself in the LED grow light industry by offering high-quality LED grow lights at a fraction of the price of other brands. With their SF4000 and HLG 550r, they've done it again.


Horticulture Lighting Group (HLG), a manufacturer of LED grow lights and other growing kits, was the first to invent the phrase "quantum board." Since then, several manufacturers have launched quantum boards using Samsung chips and good drives. And one of them is the Chinese company Spider Farmer, which produces high-quality LED grow lights.


Spider Farmer can provide the same advantages as HLG, but at a far cheaper cost. In this comparison, we will evaluate the SF4000 and HLG 550r to see how they stack up against one another.


Different strengths distinguish the HLG 550r and SF4000 grow lights in terms of coverage area. The HLG 550r is designed to cover 6x6 feet of vegetation and 5x5 feet of flowers, whereas the SF4000 can fit 5x5 feet of vegetation but only 4 feet of flowering plants. The HLG 550r tends to be better for vegetation, whereas the SF4000 is more suited for flowering plants.


Both the HLG 550r and the SF4000 offer exceptional efficiency. In fact, the effectiveness of these two grow lights is nearly identical. In comparison to the SF4000's efficiency of 2.7 umol/J, the HLG 550r's efficiency is 2.65 umol/J. But in order to get the best results from each light, it's important to consider how much space you need for your plants to grow as well as how many plants you want to grow at once.


In terms of comparing the spectrums of these two grow lights, the HLG 550r has a spectra of 3500K. However, the HLG 550r diodes only generate a small amount of additional blue light, which is absorbed mostly by foliage but also by blooming plants, in addition to increased red intensity, which promotes rapid plant growth.


While the SF4000 contains white, blue, red, and infrared LEDs (3000K, 5000K, 660nm and IR 760nm). This spectrum is ideal for all phases of a plant’s life cycle and promotes the development of deep green leaves, strong stems, and robust flower production. Both grow lights have been designed with the needs of both indoor and outdoor plants in mind, making them equally effective in either environment.


However, the HLG 550r has already been discontinued by the manufacturer, so you might not be able to find it anywhere. Therefore, SF4000 may be a more viable option for you since it's available in the market and can be purchased from Amazon or other online retailers.
