                • Only suitable for several pots

                Relassy 15000Lux Sunlike has the C-clamp design for easy setup. The 18in gooseneck makes it easy to adjust the angle and the height of the LEDs from the plant pots for the best effectiveness. Each light has a 120° lighting angle, quite wide to cover a large place.

                The bulbs have a long lifespan, up to 50,000 hours, and are replaceable. The input wattage is very low as well, just about 20W. Moreover, the light is very affordable. Together, Relassy 15000Lux Sunlike is a really nice budget choice.

                Besides, the housing is made of aluminum and air vents for better heat dissipation. However, Relassy 15000Lux Sunlike with C-clamp design has a limited upgradeability. So, it is suitable for small indoor succulents, from two to three pots.

                Best For Herbs: Roleadro 1000W Grow Light

                Pros
                • Extracts the most useful lights from the full spectrum
                • Higher PAR value and Lumen output
                • Exclusive LED Bead & Zener Design
                • Effective Heat-Removal System
                Cons
                • Narrow lighting angle

                Roleadro 1000W is a unique grow light. It extracts the most useful lights from the full spectrum, which means the light it produces is even better than sunlight; so the yield can increase by up to 50%.

                Roleadro 1000W provides higher PAR value and Lumen output. The higher these values are, the better for the photosynthesis of the plant. Most of the led grow lights have the reflector design to enhance the electricity efficiency and light density, however, Roleadro 1000W does not. It features exclusive LED Bead & Zener Design so that every LED can work independently and if one LED is broken, it won’t affect nearby LEDs. Moreover, LED Bead & Zener Design can stand even higher than 70℉.

                In addition to an aluminum heat sink and two high-speed fans, Roleadro 1000W features a built-in temperature controller to quickly dissipate, keeping the lamp cool and durable.

                There is only one drawback, which is that the lighting angle is a bit narrow - just 90 degrees. So the lamp won’t cover a very large area.

                Cons
                • Not waterproof

                King Plus 1200w consumes only 185W but produces an impressive output power, 1200W. The lamp has two modes: Veg and Bloom. The Veg mode includes blue LEDs and white LEDs for plant’s germination, sprouting, and root development phases. The Bloom mode includes red LEDs and white LEDs, preventing chlorophyll from breaking down. When both switches are on, all the LEDs are on, especially good for flowering and fruiting phases.

                Like other lamps above, King Plus 1200w features a powerful cooling system, enduring a withstandable temperature, enhancing the lifespan of the lamp. With the price, I expect King Plus 1200w is waterproof but it is not. This is considered a drawback.

                How To Choose The Best Full Spectrum Led Grow Lights?

                PPFD Value & PAR Value/Lumen are two crucial specs. These two specs show the light density. The higher the light density is, the better the photosynthesis of the plant is.

                Input and output wattage: You may want to compare these two wattages. Some lamps with special design allow them to multiply the input wattage and produce impressive output power. Such as, MARS HYDRO TS 1000W consumes only 150W but produces 1000W thanks to the Reflector design.

                Lifespan: A led grow light should last at least 50,000 hours. Some even last for more than 100,000 hours.

                Other things you may examine when choosing a led grow light are Lighting angle, Lighting field, Timer function, Cooling system, and Safety features.

                Which Brands Make The Best Full Spectrum Led Grow Lights?

                Viparspectra

                • ViparSpectra is the Leading LED Grow Lights brand on Amazon. They are an American LED grow light manufacturer with more than 10 years of experience.

                Mars-hydro

                FAQs

                Are all LED lights full spectrum?

                No. Even white LED lights don’t produce a full spectrum. If you want a full spectrum LED light to grow plants indoors, you’ll need a specialized one.

                How many watts per plant for LED Grow Lights?

                You'll need at least 32W/sq.ft. However, I recommend about 50 - 80W/sq.ft.

                How far should LED Grow Lights be from plants?

                Here are some suggestions

                - Acclimation Period: 36-40 inches

                - Young Vegetative: 32-36 inches

                - Vegetative Stage: 24-32 inches

                - Flowering Stage: 12-24 inches

                What are the pros and cons of LED Grow Lights vs. HPS?

                Overall, I favor a full spectrum LED light over an HPS (High Pressure Sodium) light. First, full-spectrum LED lights produce IR to UV wavelengths, which is sunlike, wwhileHPS lights only produce red and orange wavelengths. Second, LEDs are more environment friendly as HPS lights use toxic gas and metals. Third, LEDs are more energy-efficient. And last, LEDs have lower operating temps and last longer.

                How long should i keep the light run every day?

                Here are some suggestions

                - Acclimation Period: 10 hours (VEG mode)

                - Young Vegetative: 12 hours (VEG mode)

                - Vegetative Stage: 18 hours (VEG & BLOOM mode)

                - Flowering Stage: 12 hours (VEG & BLOOM mode)

                Conclusion

                Full-spectrum LED Grow Lights are one of the best options for indoor hydroponic. I hope this review can help you choose the best fit grow lamp for your small garden.
