Overview
Mushroom and microgreen cultivation rarely needs high wattage — it needs the right low-power light spread evenly across humid, shelf-based growing areas. The Koray ARZ is a low-power mushroom grow light with a wide-angle lens, IP66 waterproofing and very low heat output, purpose-built for mushroom houses, microgreen racks and hydroponic leafy greens. All figures below come from Koray’s official ARZ spec sheet and product page (factory-measured, tolerance ±10%).

The ARZ series is certified CE / RoHS / FCC. The ARZ2H carries a 35,000-hour lifespan with an operating temperature of −30 to 40 °C.
Energy Efficiency That Changes the Running Cost
Per Koray’s spec sheet, the 7 W ARZ saves about 60% of energy compared with an 18 W fluorescent tube, and its 2.7 µmol/J efficiency is 42% higher than the 1.9 µmol/J typical of conventional mushroom lights. Surface temperature stays only about 2 °C above ambient, so the fixture can run in tight, humid mushroom rooms without adding heat stress to the crop.
Wide-Angle Coverage for Shelves
The 160° wide-angle lens spreads light over 1.2 m² from a 0.3 m mounting height — enough for a standard shelf tier with fewer fixtures. A 60° spot version (15 W) is available for focused applications such as column-style or bag cultivation.
IP66 and Simple Series Wiring
Mushroom houses are among the most humid growing environments. The IP66-rated housing withstands misting and condensation, while low-voltage DC input (24 V, 48 V optional) keeps installation safe. Up to 12 ARZ units (7 W) or 6 units (15 W) can be linked in series from one power source.
RX-ARZ2H: Higher Output for Leafy Greens
For growers who need more intensity, the RX-ARZ2H dual-row bar runs at 60 W on AC100–240V with Samsung LEDs (2.4 µmol/J): 280 µmol/m²/s at 0.15 m, 250 µmol/m²/s at 0.2 m, PPF 144 µmol/s, covering 0.4 × 1.2 m per unit. It carries a built-in driver for plug-and-play install and links up to 10 units (120 VAC) or 20 units (230 VAC).
Applications
- Mushroom cultivation (button, oyster and specialty varieties)
- Microgreens and sprout racks
- Hydroponic leafy greens
- Plant factories and container farming
FAQ
Q: How much can the ARZ save on electricity?
Per the spec sheet, the 7 W ARZ uses about 60% less energy than an 18 W fluorescent tube while delivering 2.7 µmol/J — 42% higher efficiency than typical 1.9 µmol/J mushroom lights.
Q: Is it safe in humid mushroom rooms?
Yes. The fixture is rated IP66 waterproof, and the surface stays only about 2 °C above ambient, so it is safe in high-humidity, tight spaces.
Q: How many fixtures can be connected?
Up to 12 units (7 W) or 6 units (15 W) in series on DC input; the ARZ2H links up to 10 units at 120 VAC or 20 at 230 VAC.
Q: Where do these figures come from?
All values are from Koray’s official ARZ spec sheet and product page (factory-measured; tolerance ±10%).
