MARS HYDRO TS3000 420W LED Grow Light — Full-Spectrum, Energy-Efficient for 4'x4' Bloom / 5'x5' Veg

MARS HYDRO 420W TS3000 is a high-efficiency, full-spectrum LED grow light engineered to replace 600W HPS and deliver uniform coverage for 4' x 4' bloom or 5' x 5' veg canopies.

The TS3000 combines a sunlike full spectrum, an upgraded diode layout and a reflective aluminum hood to give indoor growers higher photon efficiency with lower energy use. It ships with a removable power supply and offers both a manual dimmer box and optional smart control via Mars Hydro iConnect/iHub/iControl accessories (sold separately). Designed for hobbyists and commercial growers alike, this fixture focuses light uniformly across medium-sized tents and rooms while improving light penetration and crop response across plant stages.

How does the TS3000 create even light across a 4' x 4' or 5' x 5' canopy?

The TS3000 uses a new diode layout, denser in the center and more sparse at the edges, paired with a patented white reflective hood angled at 120° to redistribute output. This combination broadens effective coverage and reduces hot spots so plants at the edges receive usable photons similar to the center.

• Diode arrangement optimized for uniform PPFD distribution
• 120° reflective hood increases spread and intensity
• Ideal coverage: 5' x 5' for veg, 4' x 4' for bloom
• Removable power supply and 2 m cord for flexible placement

What spectrum and efficiency can I expect for different growth stages?

The light delivers a sunlike full spectrum spanning key bands including 400–700 nm and extended inputs near 730–740 nm. That full-range output supports seed-to-flower development while the TS3000's photon metrics make it energy efficient compared with older HPS/MH fixtures.

• Sunlike spectrum: red IR 730–740 nm plus 3200–4200K and 5200–6800K components
• Measured output: up to 1210 μmol/s PPF and typical PPF 1151 μmol/s
• High PPE: around 2.7 μmol/J for efficient light-to-photon conversion
• Recommended use: veg 5' x 5', bloom 4' x 4'

Can I control the TS3000 remotely or adjust intensity for different cycles?

The TS3000 includes a 2-in-1 dimmer box with a manual knob for quick intensity adjustments plus an expandable smart mode. Add Mars Hydro iConnect, iHub or iControl (sold separately) to enable Wi‑Fi/Bluetooth scheduling, sunrise/sunset dimming and multi-fixture synchronization via the Mars Hydro App.

• Manual dimmer knob for immediate output changes
• Smart mode compatible with Mars Hydro controllers (optional)
• App features: scheduling, auto-mode, grow recipes and grouped control
• Allows simultaneous smart and regular fixture operation

What performance gains and savings does the TS3000 offer compared to HPS?

The TS3000 is positioned as a budget-friendly upgrade to traditional HID systems, offering higher photon efficiency and lower power draw. Users typically see improved photon delivery per watt and the manufacturer reports energy savings while maintaining competitive yields.

• Replaces 600W HPS while using roughly 420W, lowering power consumption
• Higher photon efficiency versus older HPS/MH systems
• Manufacturer PPF/PPE figures: 1210 μmol/s PPF and ~2.7 μmol/J PPE
• Designed to boost canopy light use with less heat output

Who is this for: The MARS HYDRO TS3000 suits hobby growers upgrading from HID systems, small commercial operators running multiple medium tents, and anyone who wants a compact, efficient, full-spectrum fixture for 4' x 4'–5' x 5' canopies. If you need a reliable LED with manual dimming now and optional smart scheduling later, the TS3000 gives flexible control, wide, even coverage and an energy-aware footprint.
