MARS HYDRO TS3000 420W LED Grow Light – Full Spectrum, Dimmable, 4x4 to 5x5 ft Coverage for Indoor Grow Rooms

Powerful full-spectrum performance for indoor growing

The MARS HYDRO TS3000 delivers a robust 420W of LED light designed to support plants from seed to harvest. With a sunlike spectrum and an efficient design, it helps create healthy growth in compact rooms, grow tents, or greenhouse spaces. The light is suitable for vegging in a 4' x 4' area and blooming in a 5' x 5' space, offering steady coverage with minimal hotspots.

2-in-1 dimming: manual and smart control

The TS3000 includes a versatile dimmer box that blends a simple manual knob with an expandable smart mode. When paired with compatible Mars Hydro devices such as iConnect, iHub, or iControl, growers can unlock remote control via the Mars Hydro app. Features like sunrise/sunset dimming, schedules, and grow recipes help tailor light exposure to plant needs without sacrificing convenience. A daisy-chain option lets you link multiple fixtures for larger installations while keeping control centralized.

• 2-in-1 dimmer: manual knob plus expandable smart mode
• WiFi/Bluetooth app control via compatible Mars Hydro controllers
• Sunrise/sunset dimming, schedules, and grow recipes
• Simultaneous operation of smart and regular grow lights

Optimized spectrum and uniform coverage

The light uses a refined diode layout with dense center illumination and sparser edges, delivering more uniform light across the canopy. The patented white reflector hood offers a 120° refraction angle to widen coverage and boost light intensity where it’s most needed. This design, combined with a removable power supply, supports both compact personal tents and larger commercial spaces.

• Sunlike full spectrum (730–740 nm reds, 3200–4200K warm whites, 5200–6800K cool whites)
• Broad coverage suitable for 4' x 4' vegetative areas and 5' x 5' bloom zones
• Patented reflector with 120° distribution to maximize canopy absorption
• Removable power supply and 2 m extension cord for flexible placement

Efficiency and growth potential

Compared with traditional HPS/MH lighting, TS3000 emphasizes efficiency and output. It provides 1210 μmol/s PPF with a PPE of 2.7 μmol/J, aiming for stronger photon efficiency and potentially higher yields in appropriate setups. The design supports energy-conscious operation without compromising spectrum quality, which can be beneficial for growers seeking steady, reliable results over time.

• 420W equipment that can replace a 600W HPS in many configurations
• Approximately 40% lower energy use compared with 600W HPS
• 50%+ higher photon efficiency; near 30% higher yields vs traditional fixtures
• Built for both residential rooms and larger commercial rooms

Real-world use and setup ideas

In a home grow tent, place the TS3000 to deliver even coverage across the full canopy, then scale with a daisy-chain for larger tents or greenhouses. In a commercial setup, pair multiple units in a grid and use the app for coordinated light cycles. The combination of smart and manual control, plus a solid build, makes this light a flexible option for growers exploring consistent, repeatable results without prescriptive guarantees.
