Mars Hydro TSL2000 Offers 30% More Yield Than HPS/MH While Cutting Energy Costs

Efficient full-spectrum lighting delivers powerful coverage with 25% less energy for indoor grows.

The TSL2000 LED Grow Light delivers efficient, high-yielding performance with a rectangular light footprint, making it perfect for 4-6 indoor plants in grow tents, small rooms, cabinets, and plant shelves. With 300W of power and 704 premium diodes, it replaces a 400W HPS while cutting energy costs by 25%. Offering 3’x5’ veg coverage and 2’x4’ flowering coverage, this light is ideal for both home cultivation and decorative floral displays. The patented reflective hood design maximizes light intensity and absorption, ensuring higher yields with minimal energy waste.

Why It’s the Smartest Investment for You

Built for growers who want precision coverage, the TSL2000 is 50% more photon efficient than outdated HPS/MH lights, producing 717 µmol/s PPF and 2.6 µmol/J PPE, translating to 30% more yield per watt. Its full-spectrum output (400-700nm) is optimized for plant photosynthesis, with IR (730-740nm) added for bigger, denser buds. Dimming and daisy-chain functionality allow up to 15 lights to be connected, giving growers full control over brightness levels while minimizing power waste. Certified by CE, ETL, RoHS, and UKCA, it boasts 50,000-hour durability and a 5-year warranty with local support.

Is the TSL2000 Energy-Efficient?

Absolutely. While traditional HPS fixtures average just 1.3–1.7 µmol/J, the TSL2000 delivers 2.6 µmol/J, providing higher light output per watt while reducing operating costs. Whether you're growing hydroponically or in soil, this affordable, high-efficiency LED grow light ensures vigorous plant growth without excess energy consumption.

Features

  • Low Power Consumption: Uses only 300W while replacing a 400W HPS, saving 25% electricity
  • High Performance Efficiency: Produces 717 µmol/s PPF with a 2.6 µmol/J PPE, delivering 50% more photon efficiency and 30% higher yields than traditional HPS/MH lights

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.
