Description
Note: this is a one-off light.
We have this one colourful QB light that we didn’t know what to do with. By itself it’s not really something we’d sell as a serious light, so we’ve added two GrowOpz QB panels, and made it into an underdriven 300W light. Now it’s a real light.
4 rope ratchets included, watt meter included, so you can set it to 300W.
Spaceship Prototype LED Grow Light – 300W Tuned Output
🔧 Configuration
Driver: Mean Well HLG-320H-48B (dimmable)
Recommended operating power: ~300W (user-adjustable via watt meter, included)
Main Board Spectrum:
- 320 × Samsung LM561C S6 (3500K)
- 64 × 660nm Deep Red
- 32 × 730nm Far Red
- 32 × 620nm Red
- 32 × 450nm Blue
- 16 × 395nm UV
- 16 × 365nm UV
Side Bars:
- 288 × Samsung LM301B (3333K average)
- Warm white full-spectrum supplementation
🌱 Spectrum Design
This is a true full-cycle flowering spectrum, combining:
- High-efficiency white base (LM561C S6 / LM301B) for bulk photon output
- 660nm deep red for flowering efficiency and yield
- 730nm far red for Emerson effect and flowering response
- 450nm blue for structure and plant health
- 620nm red to broaden the red band
- UV (365–395nm) for resin, stress response, and secondary metabolite production
The result is a balanced, aggressive flowering spectrum with enhanced terpene and resin potential.
💡 Performance & Design
- Total draw (recommended): ~300W
- Main board: ~200W (underdriven to 83% nominal, for efficiency & longevity)
- Side bars: ~100W combined (underdriven to 66% nominal, for efficiency & longevity)
- Footprint: 58 × 63 cm fixture size
The side bars increase edge coverage and uniformity, reducing hotspots and improving light distribution across the canopy.
🌿 Coverage
- Flowering (high intensity): 90 × 90 cm
- Flowering (balanced): up to ~100 × 100 cm
- Vegetative: up to ~120 × 120 cm
❄️ Thermal & Efficiency Benefits
- All components are underdriven relative to max ratings, resulting in:
- Lower heat output
- Higher efficiency (lm/W)
- Extended LED lifespan
- Improved reliability
🎛️ Control
- Includes dimming via Mean Well B-type driver
- Supplied with a watt meter, allowing you to:
- Set exact power draw (e.g. 250W / 300W / max)
- Tune intensity for different growth stages
