Exclusive Limited Time Offer: GrowAce.com customers will receive a FREE pair of Yield Lab LED grow room glasses with the purchase of the Mars Hydro 300W TSW 2000 LED Grow Light ($29.95 value!)

The Mars Hydro TSW 2000 is a highly efficient, budget-friendly LED grow light designed specifically for home cultivation and indoor gardening enthusiasts. Engineered to optimize crop development from seed to harvest, it draws a true 300 watts of power while easily replacing a traditional 450W HPS/MH lighting system. Its innovative, fanless aluminum design ensures silent operational passive cooling while significantly dropping energy bills by managing heat effectively.

• Energy Efficiency & Savings: Consumes only 300W of electricity while delivering performance that replaces a standard 450W HPS/MH light, saving up to 40% on energy.

• Patented Reflective Hood: Features a 120° refraction angle aluminum reflector that captures scattered light, increasing light utilization efficiency by 25% without causing heat stress or plant burn.

• Sunlike Full Spectrum Output: Delivers a versatile light spectrum (400–700nm PAR) rich in deep red and supplemental infrared (730–740nm) to drive heavy flowering and larger buds.

• Precision Dimming & Multi-Connection: Built with an independent dimming knob allowing 0–100% brightness adjustments alongside a daisy-chain feature connecting up to 30 fixtures.

• Silent Passive Cooling & Detachable Driver: Built with a fanless, pure aluminum heat sink for completely silent operation, combined with a removable driver and 2m extension cord to keep ambient tent heat down.

• Optimal Grow Footprint: Perfectly tuned to cover a 4' x 4' footprint during the vegetative growing stage and a focused 3' x 3' footprint for the final flowering cycle.

• Globally Certified & Warranted: Backed by industry-standard safety certifications (CE, ETL, RoHS, UKCA) along with an official 5-year limited manufacturer warranty.

Equipped with a patented highly reflective aluminum hood design and a full-spectrum output, this light delivers superior photon efficiency across vital photosynthetic wavebands. Featuring convenient integrated dimming controls and advanced daisy-chain capabilities, growers can seamless handle up to 30 lights concurrently. Ideal for small rooms, closets, or 4'x4' grow tents, the TSW 2000 maximizes light utilization to boost indoor yields safely and effectively.
