              Best For Hydroponics: Growstar UFO Led Grow Light 150W

              Growstar UFO Led Grow Light 150W
              Growstar UFO Led Grow Light 150W
              8.8Great
              Pros
              • Full spectrum for all stages of plants growth
              • 90 - 120 degree Angle Design
              • Eco-friendly & Energy Saving
              • Effective Cooling Fan System
              • Affordable
              Cons
              • Quite small; Indoor use only

              I recommend Growstar UFO Led Grow Light 150W for many reasons. First, it is affordable yet very functional and effective. It has a full spectrum, including IR and UV, for all stages of plant growth. Red light is to promote photosynthesis, sprout, and blossom.

              Blue light is good for germinating seeds, helping stalks and roots grow stronger, promoting left growth; but at a certain level, it inhibits photosynthesis. UV light prevents excessive growth, disinfection, and sterilization, and thus reduces plant disease.

              IR light helps blossom. 3000k Warm white light mode and Cree COB mode blend these lights, which are an essential factor for photosynthetically active radiation, making plants healthier.

              Growstar UFO Led Grow Light 150W has a 90-120 degree lighting angle, which is scientifically proven for more effectiveness - creating a wilder field of lighting and increasing the brightness. The cooling system includes fans, aircraft-grade aluminum heat sink and heat-conducting case that helps to emit heat faster from the inside of the lamp to the outside. This enhances the light's lifespan.

              Moreover, this grow-light consumes only about 60W. Growstar also emphasizes on the product’s quality, safety features, and environmental impact, ensuring UFO 150W are both eco-friendly and energy-saving.

              However, UFO 150W is quite small and not water-proof. So, use it indoor only for a small hydroponics system.

              FAQs

              What is the difference between LED and COB LED?

              COB LED is multiple LEDs on a single module, thus, it helps to blend lights from IR to UV. As a result, COD LED is much more alike natural sunlight and is better for the plant.

              Which is brighter cob or LED?

              COB LEDs are brighter, consume less electricity but output a higher-power light. COB LEDs are better than traditional LEDs in many ways.

              How long do COB LEDs last?

              They last at least 30,000 hours; some even last for more than 50,000 hours.

              Do COB LED get hot?

              Yes. A COD LED can get very hot. So it is necessary to choose a COD LED with an effective cooling system.

              How does a COB LED work?

              COB stands for Chip-on-Board, which is a technology that is used to mount multiple LEDs onto a single module. This helps blend all the lights from IR light to UV light, mimicking the natural sunlight for maximizing the plant development.
