Up to 20% more light output. Same energy cost. Australia's favourite HPS lamp.

Lucagrow HO HPS lamps produce significantly more photon output than standard HPS at the same wattage — no ballast changes, no increase in running costs. Available in 400W and 600W, they’re one of the most widely used HPS grow lamps in Australia for good reason.

Why Lucagrow HO Outperforms Standard HPS

20% More Light, Same Power Draw

More lumens at the same wattage means improved PPFD, better canopy penetration, and stronger flowering performance without touching your electricity bill. A direct upgrade over any standard HPS lamp in your current setup.

Optimised Flowering Spectrum

Spectral distribution weighted toward the red/orange range (550–700nm) that drives chlorophyll absorption, bud development, and overall bloom productivity. Tuned for flowering — not a general-purpose HPS adaptation.

Stays Brighter for Longer

Lucagrow HO lamps maintain output stability across their operational lifespan. Consistent PPFD run-to-run rather than rapid lumen depreciation after the first few hundred hours.

Drop-In Ballast Compatibility

Compatible with standard 400W and 600W HPS ballasts — magnetic and digital. No system changes required.

Is Lucagrow HO better than standard HPS for flowering?

Yes. At the same wattage and energy draw, Lucagrow HO produces up to 20% more usable light — translating directly to improved bud density, canopy penetration, and yield with no additional running cost.
