270 Watt Advanced Spectrum MAX 3w-Chip Modular Grow Light Kit PROFESSIONAL GRADE PERFORMANCE: This is the industry standard for commercial growing and indoor home application. The low heat, reflective aluminum, cost effective unit provides a complete spectrum of light from seedling to harvest. KEEP YOUR COOL: These are the coolest running LEDs on the market. The aluminum body of the panel is designed with multiple cooling ports and fans to to maximize efficiency and allow you to place lights close to your plants without worrying about heat damage, such as bleached or fried leaves. MODULAR DESIGN: Customizations and repairs are fast and easy with this model. Most LEDs would be rendered useless if a diode goes out, but these modular LEDs diodes only affect a single diode. DOUBLE POWERED: Combines white, blue, and red spectrum output. The blue spectrum (430-460nm) is on the lower end of the spectrum and promotes the growth of leaves during the vegging stage; the red spectrum (630-730 nm) promotes flower growth along with budding during your flowering stage. LONG LASTING: Our advanced spectrum LED's have a 50,000 hour lifespan, which is more than twice the lifespan of HID bulbs.
