MARS HYDRO TSW2000 (dimmable) 2.6µmol/J 300W LED flowering/grow lamp

The Mars Hydro TSW2000 300W dimmable LED grow and bloom light is a powerful full-spectrum grow light designed for medium-sized grow tents and professional indoor growing environments. With a high efficacy of 2.6 µmol/J , a true power consumption of 300W, and deep light penetration, this LED grow light delivers maximum performance during both the vegetative and flowering phases.

The TSW2000 is one of the best-selling 300W LED grow lights for 100x100 and 120x120 grow tents thanks to its ideal balance of yield, energy efficiency, and ease of use. Suitable for 3–6 plants in full cycle .

Powerful Full Spectrum Lighting for Growth & Flowering

The optimized full spectrum (white, red and additional wavelengths) supports:

• Rapid root development
• Strong vegetative growth
• Compact internodes
• Maximum flower formation
• Higher yield per m²

Optimal Coverage

• Vegetative stage: 120 × 120 cm
• Flowering stage: 100 × 100 cm

Perfectly suited for standard grow tents of 100×100 cm and 120×120 cm .

Dimmable & Daisy-Chain System

The integrated dimmer allows you to precisely adjust the light intensity for each growth phase:

• Lower intensity for seedlings
• Controlled growth in the vegetative phase
• Maximum output during flowering

The daisy-chain function allows multiple TSW2000 lamps to be linked and centrally controlled, ideal for scalable indoor growing spaces.

Reflective Hood Design & 684 SMD LEDs

The TSW2000 features 684 high-quality SMD LEDs combined with the signature reflective hood design. This ensures:

• Uniform PPFD distribution over the entire canopy surface
• Deeper light penetration
• Fewer hotspots
• Maximum light utilization
• More efficient energy use

With a maximum PAR output of up to ±910 µmol/m²/s, this lamp delivers powerful performance without excessive heat generation.

Completely Silent & Energy Efficient (0 dB)

Thanks to passive aluminum cooling, the TSW2000 operates completely silently.

• No fans
• No vibrations
• No extra sound

Ideal for bedrooms, apartments and quiet indoor spaces.

With only 300W actual consumption, this lamp replaces a ±400W HPS system, with lower energy costs and significantly less heat output.
