Engineered for heavy-duty industrial performance, this elite, self-contained lighting solution is built to handle every stage of your crop's life cycle—from fragile seedling propagation and dense cloning work to active vegetative training and early flowering phases. Traditional dual-tube fixtures often lack the deep footprint width needed to cover full multi-tray configurations, forcing growers to hang multiple separate units. The SeaHawk Star Light 4-lamp system solves this infrastructure challenge by expanding the physical chassis width to 42cm, packing four commercial-grade 55-Watt linear T5 tubes (220 Watts total system power draw) into a single high-efficiency housing. Fabricated with a rugged, heavy-gauge steel shell featuring a premium powder-coated exterior finish, the interior is outfitted with a high-purity hammer-tone aluminum reflector matrix. This dimpled reflective design splits and scatters intense light rays at wide, overlapping angles, completely eliminating dangerous under-hood hot spots while driving high-lumen photon velocity deep through thick fan leaves. Operating with an internal, high-frequency electronic ballast, this plug-and-play fixture hooks directly into any standard 240-Volt wall socket, completely cutting out the clutter, weight, and excess heat of external ballast boxes. Now offered at a premier clearance value of just $55.00 (down from $85.00), this complete kit includes an extra-long 2-meter utility power lead and a full set of four 55W high-lumen T5 tubes, delivering unbeatable commercial outfitting value for multi-tier indoor vertical farms, commercial propagation lines, and boutique nurseries looking to scale up production cost-effectively.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e Broad-footprint multi-tray propagation benches, high-density multi-tier vertical farming racks, low-heat vegetative canopy training, and cost-effective commercial facility outfitting.\u003c\/p\u003e\n\u003ch3\u003eKey Features \u0026amp;

When mounting these fixtures inside enclosed shelving racks, maintain a minimum 8cm air ventilation gap between the top of the metal housing and the shelf level above it to prevent warm air from baking the root zones of the upper crop trays.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetting Up Safety Drip Loops for Wide-Format Power Cords:\u003c\/strong\u003e Since professional nursery benches and plant propagation tents operate at high ambient humidity levels (75% to 85% RH) with active automated misting schedules, electrical safety is paramount. When routing the heavy-duty 2-meter power lead from the Star Light chassis out to your utility socket, always ensure the cable drops down into a loose, shallow U-shape bend right before it reaches the plug interface. This forms a natural \"drip loop\"—any ambient room condensation or stray spray tracking along the wire will pool safely at the bottom of the bend and drip to the floor rather than running directly into an active electrical connection.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIdeal For (Uses)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBroad Multi-Tray Commercial Nurseries:\u003c\/strong\u003e The ultimate option for high-volume operations that need to cover multiple standard seedling flats or propagation domes simultaneously under a single broad-profile fixture.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Density Vertical Multi-Tier Racks:\u003c\/strong\u003e Perfect for indoor vertical farms that want to maximize their space by packing high-intensity, low-profile lighting arrays into tight vertical shelves.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBudget-Conscious Facility Upgrades:\u003c\/strong\u003e An exceptional choice for commercial facility managers and home growers looking to capitalize on premium clearance pricing to completely refresh or scale out their vegetative lighting footprint.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/section\u003e","brand":"Holland Forge","offers":[{"title":"Default Title","offer_id":48454251282532,"sku":"7992","price":149.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/6487\/0244\/files\/ChatGPTImageMay24_2026_01_36_17AM.png?v=1779558627","url":"https:\/\/www.greenhousepolytunnels.com.au\/products\/seahawk-star-light-4-x-55w-high-output-t5-fluorescent-propagation-fixture-industrial-grade-commercial-canopy-array","provider":"Greenhouse \u0026 Polytunnels","version":"1.0","type":"link"}
