Description
The Phantom Pro 315W Ceramic Metal Halide DE lamp delivers optimized full spectrum plant biologically active radiation. This premium lamp outputs 580 μmol/s of photosynthetic photon flux (PPF 400-700nm) for superior performance in indoor grows and greenhouse environments.
UV and far-red light stimulate desirable photomorphogenic traits, allowing your crop to reach its full genetic potential.
The integrated double-jacketed design means this lamp can be operated safely without a lens, and its 20,000-hour service lifetime means less frequent lamp replacements—reducing labor and operational expense.
Designed for operation on 315W low frequency square wave ceramic metal halide ballasts. To maintain warranty, lamp must be operated on low-frequency square wave ballast.
Not intended for use in higher wattage high frequency ballasts.
Features:
- Optimized full spectrum lamp outputs 580 μmol/s (PPF 400–700nm)
- UV and far-red stimulate desirable photomorphogenic traits, allowing your crop to reach its full genetic potential
- Integrated double-jacketed design allows lamp to be open rated
Light footprint (realistic expectations)
A 315W CMH DE typically covers:
- Veg: ~ 3′ x 3′ to 4′ x 4′
- Flower: ~ 2.5′ x 2.5′ to 3′ x 3′
The Phantom Pro’s 580 µmol/s output puts it at the higher end of the CMH class, so you can expect:
- PPFD ~400–600 µmol/m²/s in a 3′ x 3′ flower footprint
- PPFD ~250–400 µmol/m²/s in a 4′ x 4′ veg footprint
(These are inferred from typical 315W CMH performance ranges.)
If you’re growing cannabis, one lamp comfortably handles one medium plant or two smaller plants in flower.
🔍 Why this lamp performs well
- Full spectrum (400–700nm) → balanced growth at all stages
- UV + far‑red → boosts resin, colour, essential oils, and natural morphology
- Open‑rated double‑jacket → safer operation without a lens
- 20,000‑hour life → fewer replacements, lower operating cost
- Low‑frequency square‑wave ballast required → stable arc, proper ignition, warranty protection
🛠 Practical placement tips
- Hang 18–24 inches above canopy for veg
- Hang 12–18 inches for flower (watch leaf temps)
- Keep good airflow — CMH runs cooler than HPS but still produces radiant heat
- In greenhouses, use it as top‑up lighting over small zones or specialty crops
