SANlight EVO 4-120 1.5 LED Grow Light | 265W Full Spectrum Commercial Hydroponic Lighting Australia

SANlight EVO 4-120 LED Grow Light | 265W Full Spectrum for 120x120cm Tents Australia

The SANlight EVO 4-120 is an Austrian-engineered 265W full spectrum LED grow light designed for 120x120cm indoor growing spaces. It delivers 725 µmol/s PPF at above 3.0 µmol/J efficacy with uniform canopy coverage across the full 1.44m2 footprint, passive silent cooling, IP65 protection, and a 3-year manufacturer warranty. For Australian growers running a standard 120x120cm tent who are not using CO2 supplementation, the EVO 4-120 operates at the optimal light intensity for standard atmospheric conditions while consuming 75W less than the EVO 5-120.

EVO 4-120 vs EVO 5-120 - Which One Do You Need?

Both fixtures cover 120x120cm. The difference is intensity and power draw. The EVO 4-120 delivers 725 µmol/s PPF at 265W, producing approximately 600 to 700 µmol/m2/s at canopy level. The EVO 5-120 delivers the same 725 µmol/s PPF at 340W but is optimised for maximum intensity applications including CO2-supplemented grows.

For most Australian hobby growers not running CO2, the EVO 4-120 is the more efficient choice. PPFD above 800 µmol/m2/s without CO2 supplementation produces diminishing returns on most crops and increases the heat management burden, which is already a challenge during Australian summers. The EVO 4-120 delivers the productive intensity range with 75W less power draw, lower running costs, and less heat generation.

Running Costs in Australia

At current Australian electricity rates of 30 to 35 cents per kWh, the EVO 4-120 running 12 hours per day through a 10-week flowering cycle consumes approximately 252 kilowatt-hours, costing around $80 to $88 in electricity for the light alone. A 600W HPS producing equivalent photon output consumes approximately 504 kilowatt-hours over the same period, costing $160 to $176. The saving of approximately $80 per cycle adds up to $240 to $320 per year for growers running three flowering cycles annually, before accounting for the reduced cooling load from lower heat output.

What the EVO 4-120 Pairs With

The EVO 4-120 is matched to the HOMEbox Ambient Q120+ with PAR+ reflective lining, which redirects photons hitting the tent walls back into the canopy and improves the effective PPFD delivered to plants. For complete environmental monitoring, the Bluelab Combo Meter measures pH, EC, and temperature simultaneously for precise nutrient solution management through the full flowering cycle.

Frequently Asked Questions

Is the EVO 4-120 suitable for a 120x120cm tent? Yes. The EVO 4-120 is purpose-engineered for 120x120cm with asymmetric secondary optics that distribute light uniformly across the full footprint. Growers not using CO2 supplementation will find the 4-120 delivers the right intensity for the canopy area without excess heat.

Can I dim the EVO 4-120? Yes. The EVO 4-120 is compatible with SANlight Bluetooth and magnetic dimmer accessories for precise intensity control from germination through to late flower.

How does the EVO 4-120 handle Australian summer temperatures? The passive fanless design produces significantly less radiant heat than HPS fixtures, which reduces the cooling burden during summer. Running lights overnight during extended heatwaves is a common approach for Australian growers to avoid peak ambient temperatures. See our guide on cooling a grow tent during Australian summer.

Where is the SANlight EVO 4-120 made? Designed and manufactured in Vorarlberg, Austria, with Osram and Seoul Semiconductor LED components.
