Bulb HPS/MH 600 Watt

600 Watt HPS and MH bulbs — our professional-grade selection

If your goal is maximum harvest weight per square metre, 600W has been the answer for four decades. It is the wattage where HID technology hits peak efficiency: enough lumens for deep canopy penetration, without the disproportionate heat and power draw of 1000W setups. Browse the full HPS/MH bulb range to compare wattages, or pair your bulb with a matching ballast.

Why 600W outperforms on lumens per watt

A 600W HPS bulb like the Philips GreenPower 600W produces 88,000 lumens at 142 lm/W — the highest efficiency ratio of any HID wattage available. For context, 400W HPS sits around 140 lm/W and 1000W drops to 135 lm/W. That 75% increase in light output over 400W, for only 50% more electricity, is why 600W remains the commercial benchmark despite the rise of LED. Add a PPF of 1100 µmol/s and 14,000-hour rated lifespan, and the case for 600W on any 1-1.5 m² canopy becomes hard to argue with.

Dual-spectrum HPS for single-bulb cycles

The Philips GreenPower 600W and the Sylvania Grolux 600W are both HPS dual-spectrum bulbs. Each adds roughly 30% more blue to the base red-orange spectrum, making them usable through vegetative growth and flowering without swapping bulbs. The GreenPower maintains 90% PPF at 10,000 hours and is the reference in European commercial greenhouses. The Grolux delivers comparable performance at a more accessible price point, with a colour temperature of 2050K. Note that the Grolux is an HPS — not an MH, despite occasional mislabelling online.

The two-bulb approach: MH for veg, HPS for bloom

Growers who want to optimise each phase separately run two different bulbs. For vegetative growth, the Lumatek MH 600W produces 50,000-58,000 lumens depending on CCT (4200K cool white or 6000K daylight), with a PPF of 729-750 µmol/s. Pulse-start technology means faster warm-up and better PAR maintenance over the 10,000-hour lifespan. When you flip to 12/12, switch to the Lumatek HPS 600W or the Superplant Super Red 600W for the warm spectrum that drives dense flower formation.

• Superplant Super Red 600W: HPS with enriched red spectrum, budget-friendly bloom option.
• Lumatek MH 600W: metal halide, 50,000-58,000 lm, PPF 750 µmol/s, pure vegetative bulb.

Heat management: the non-negotiable requirement

600W is not the wattage for corner-cutting on ventilation. The heat load requires a dedicated airflow strategy. Plan for a 600 to 800 m³/h extractor in a standard 120×120×200 cm tent, and size up to 800 m³/h the moment you add a carbon filter (which reduces effective airflow by 25-30%). An air-cooled cooltube reflector evacuates heat directly at source, letting you hang the bulb 40-50 cm above the canopy instead of 60 cm. For a plug-and-play installation, our 600W lighting kits include matched ballast, reflector and bulb in one package.
