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 TSL 2000 LED Grow Light ($29.95 value!)

The Mars Hydro TSL 2000 is an updated, highly effective 300-watt LED grow light specifically engineered to fit elongated indoor cultivation spaces. Moving beyond traditional square layouts, its unique rectangular physical framework makes it the definitive option for 2'x4' and 3'x5' commercial or hobbyist grow setups. Featuring an upgraded patented reflective hood design, the fixture captures and concentrates light that would otherwise disperse in all directions, redirecting it downward to maximize photon absorption across the entire plant canopy.

• Tailored Rectangular Form Factor: Specifically engineered with an elongated shape optimized to deliver maximum, uniform footprint coverage across rectangular 2'x4' and 3'x5' growing spaces.

• Patented Reflector Hood Technology: Features a uniquely angled physical hood design that captures escaping side-angled light and refocuses it directly onto the canopy to prevent energy loss.

• Sun-Like Full Spectrum Output: Delivers a specialized mix of PAR wavelengths (400–700nm), warm whites, and vital Far-Red/IR (730–740nm) light to heavily accelerate photosynthesis and bud weight.

• Highly Efficient Power Delivery: Uses only 300 watts of true wall power while seamlessly matching or exceeding the raw yields of an electricity-heavy 400W HPS system.

• 0–100% Precise Group Dimming: Equipped with an adjustable external dimming knob that allows seamless daisy-chaining of up to 15 separate fixtures for simplified, master-control operations.

• Remarkable Efficacy and PPF: Delivers an impressive Photosynthetic Photon Efficacy (PPE) of 2.6 μmol/j and a total light output of up to 778 μmol/s, supporting massive yield capacities up to 2.3g/W.

• Certified Multi-Region Safety: Approved with global safety designations including ETL, CE, RoHS, and UKCA, guaranteeing 50,000 operational hours backed by local repair access.

This commercial-grade system easily substitutes a conventional 400W HPS/MH setup while lowering electricity consumption by 25%. Built with 704 high-end BridgeLux chips, it produces a tailored, sun-like full spectrum that incorporates crucial infrared light to trigger superior budding and robust flower expansion. Outfitted with an external driver for enhanced heat management, a 0–100% manual dimming dial, and multi-light daisy-chain capabilities, the TSL 2000 delivers an optimized, energy-saving environment for all stages of plant development.
