SeaHawk 740mm Deep Bowl Vertical HID Reflector – Commercial Large-Format Parabolic Distribution Hood
Deliver an ultra-wide, uniform footprint of photosynthetic photon energy across extensive multi-bench canopies with the SeaHawk Deep Bowl Reflector. A time-tested, commercial-grade favorite among legacy horticultural managers and high-volume indoor growers, this massive parabolic dome is specifically engineered to orient and fire high-intensity discharge lamps in a vertical downward position. Traditional horizontal reflectors throw intense, focused lines of radiant energy directly below the bulb's arc tube, which can create volatile localized heat signatures and stunted crop spots. By mounting the lamp vertically, the SeaHawk Deep Bowl captures the uniform 360-degree radial light output of your bulb and redirects it down across an expansive geographic radius. This mechanical alignment disperses intense intersecting light rays far and wide, radically minimizing under-hood hot spots while maximizing light penetration into dense lateral branch layers. Spanning a commanding 740mm diameter and built to rugged structural specifications, this heavy-duty fixture features an optimized reflective profile that turns a single HID bulb into a wide-angle dispersion system. Ideal for scaling up extensive commercial facilities, warehouse grow lines, or high-density nursery benches, these premium reflectors are distributed in bulk packaging configurations and are available exclusively in factory carton quantities of 10 or more units.
Best For: Large-scale open room cultivation, uniform wide-angle canopy light mapping, eliminating under-hood thermal hot spots, and bulk multi-bench commercial facility scaling.
Key Features & Technical Advancements
- Vertical Orientation Optical Geometry: Operates the HID bulb in a vertical position, leveraging the lamp’s natural 360-degree radial emission to throw an exceptionally even, circular light footprint.
- Ultra-Wide Footprint Dispersion: Engineered with a broad 740mm parabolic curvature that redirects light far across your floor area, allowing wider fixture spacing while ensuring overlapping canopy coverage.
- Thermal Hot-Spot Mitigation: By bouncing light outward rather than focused directly down, this dome layout prevents radiant infrared heat from concentrating on your plant tops, reducing leaf curling and heat stress.
- Heavy-Duty Commercial Durability: Constructed from rigid, lightweight horticultural metals designed to resist warping, denting, and oxidative degradation across high-humidity grow environments.
- High-Efficiency Textured Material: Features a premium, dimpled reflective lining that diffuses harsh light rays, smoothing out uneven intensities and delivering balanced photon streams to the leaf surfaces.
- Factory Carton Logistics Optimization: Supplied efficiently in an intact, fixed factory carton configuration of exactly 10 units per box, streamlining freight economics and minimizing handling damage during facility expansions.

Advanced Vertical Light Management & Substrate Control Tips
- Optimizing Vertical Hang Heights and Crossover Footprints: Because the vertical orientation of the SeaHawk Deep Bowl throws light at a wider outward angle than horizontal hoods, correct fixture height is critical to lock in cross-canopy uniformity. Position your reflectors 65cm to 85cm above the top of your plants. Space multiple fixtures evenly across your room so that the outer edges of their light rings overlap perfectly on your benches, filling in any gaps and driving light down into your plants from multiple angles.
- Root-Zone Hydration and Substrate Coordination: The wide, uniform light footprint delivered by a vertical parabolic reflector maximizes the leaf surface area actively performing photosynthesis across your entire room. Support this high-efficiency growth by potting your crops in breathable fabric aeration pots filled with a light, highly porous 70/30 blend of Coco Coir and Horticultural Perlite. Ensure your wet-dry irrigation cycles stay flawlessly uniform by connecting your drip lines to a high-pressure Plont PPH Submersible Pump managed by an automated digital shot-timer.
- Managing Airflow and Heat in Vertical Arrays: While vertical reflectors naturally eliminate the harsh hot spots created by horizontal hoods, their large 740mm profile can trap warm ambient air rising from your plants. To keep your grow space at the ideal temperature range (24°C to 27°C), mount your main inline extraction fan high up in the ceiling to pull trapped heat out of the room, combined with a grid of oscillating fans below the hoods to keep air moving smoothly over your canopy.
- Setting Up Safety Drip Loops for Vertical Socket Leads: Because commercial open rooms and large propagation bays operate at high humidity levels, protecting your electrical lines is paramount. When routing the heavy-duty power lead from your deep bowl's vertical center socket up to your ceiling tracks and back to your remote ballasts, always ensure the cable drops into a loose, shallow U-shape bend right before it enters your line conduits. This forms a natural "drip loop"—any ambient room condensation or stray moisture tracking down the wire will pool safely at the bottom of the bend and drip to the floor rather than running directly into active electrical connections.
Ideal For (Uses)
- Large Commercial Warehouse Expansions: The ultimate option for commercial facility operators outfitting massive open rooms or warehouse rows who need a durable, wide-angle light hood to maximize coverage per light.
- High-Density Shared Nursery Benches: Perfect for propagation rooms and vegetative bays where large groups of plants are packed closely together on wide tables and require uniform light from edge to edge.
- Fragile Terpene and Essential Oil Protection: An exceptional choice for growers looking to reduce thermal stress on delicate flower tops, using the diffuse parabolic shape to minimize infrared hot spots and protect crop quality.
Oversized Item Delivery Options
Oversized, heavy, and structural goods ship via specialist freight. Freight is calculated at checkout from estimated packaged volumetric or physical weight. Carrier depot audits may adjust the rate — if the increase exceeds 10%, we will contact you before processing.
Available options include:
✔ Delivery to your closest depot for pickup — default method
✔ Direct delivery — requires an operational forklift on site unless Tailgate Delivery has been specifically requested and quoted (contact us — this cannot be selected at checkout)
✔ Tailgate hydraulic lift delivery — must be specifically requested; contact us for a quote (not available as a checkout option; extra fees apply; required if you do not have a forklift)
✔ Forklift loading at our warehouse (no extra charge if you arrange your own freight)
✔ Direct truck delivery (available in Victoria)
Important Notes:
- Shipping costs vary by location and method
- Any carton or consignment over 25–30kg (or over 200cm) must be palletised
- Without a specifically requested and paid Tailgate Delivery quote, palletised freight requires a forklift on site — otherwise the carrier will redirect to the nearest depot
- Bulky and oversized items cannot be delivered to a PO Box — provide a physical street address
- Failed deliveries, locked gates, unattended sites, or incorrect business/forklift declarations may incur carrier redelivery, demurrage, and restocking fees as set out in our Terms & Conditions
Business Delivery:
- Selecting a business/commercial delivery rate warrants that the address has an operational forklift and certified operator during business hours
- If the carrier cannot unload, the consignment may be redirected to a depot and secondary fees may apply
- Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment
See our Terms & Conditions (Article 8) for full freight and delivery rules.
Important Note on Availability & Shipping
Our warehouse is a logistics hub, not a retail showroom. Listing a product online does not mean it is stored at our Thomastown warehouse — many lines ship from supplier hubs (split fulfilment may apply).
How lead times work:
