Mars Hydro TSW2000 Delivers 30% More Yield with Its Full-Spectrum, Plant-Preferred Light

Get to Know the Mars Hydro TSW 2000 Full Spectrum 300W Dimming LED Grow Light

The TSW2000 LED Grow Light is a top choice for home growers, delivering powerful, energy-efficient lighting for 4-8 plants. With 300W of power and 704 high-efficiency chips, it replaces a 400W HPS while saving 25% on electricity costs. Designed for grow tents, small rooms, cabinets, and plant shelves, it provides 4’x4’ veg coverage and 3’x3’ flowering coverage. The patented reflective hood design enhances light distribution and absorption, ensuring stronger, healthier plant growth with full-spectrum lighting, including IR (730-740nm) for bigger buds.

Why It’s the Smartest Investment for You

The TSW2000 is 50% more photon efficient than older HPS/MH systems, featuring 716 µmol/s PPF and 2.6 µmol/J PPE, leading to 30% higher yields per watt. The dimming and daisy-chain function allows up to 15 lights to be connected, providing customized brightness control for different growth stages while reducing energy waste. Built for home growers and commercial cultivators alike, it’s certified by CE, ETL, RoHS, and UKCA, ensuring 50,000-hour durability and a 5-year warranty with local after-sales support.

Is the TSW2000 Energy-Efficient?

Absolutely. While traditional HPS fixtures average just 1.3–1.7 µmol/J, the TSW2000 delivers 2.6 µmol/J, maximizing light output per watt while keeping energy costs low. Whether you’re growing hydroponically or in soil, this affordable, high-yielding LED grow light ensures vigorous plant growth with minimal overhead.

FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants like cannabis. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.
