Eight of them on one frame make a 720-watt light for a full-size flowering footprint. The MB-8 is the frame that holds them. It carries \u003cstrong\u003eeight driver positions\u003c\/strong\u003e for a total of \u003cstrong\u003e720 watts\u003c\/strong\u003e. Positions are spaced about 5.91 in apart, so the bars sit evenly across the footprint. The bar is \u003cstrong\u003e44.57 in\u003c\/strong\u003e long and 2.21 in wide. Both TLD-2 two-channel drivers and TLD-4 four-channel drivers fit it. Mixing bar types lets one fixture carry full spectrum, deep red, far red or UV as the crop needs. One MB-8 bar comes in the box. Its listed product weight is 870 g, about 1.92 lbs.\u003c\/p\u003e\u003ch2\u003eInstalling a Quick Release Mounting Bar\u003c\/h2\u003e\u003cp style=\"text-align: justify;\"\u003eHang it straight from the ceiling with the provided hangers, or lock it into Unistrut channel. On Unistrut, two loosely threaded nuts slide into the channel before being tightened down. Each driver twists roughly 25 degrees to seat on the bar. Flip every other driver so the power leads line up male to female down the row. TDC-2, TDC-3 or TDC-4 daisy-chain cords link the drivers, chosen by the gap between them. A TDC-120, TDC-240 or TDC-277 splitter cord then brings power and the controller link to the group. Check the manual's per-cord driver limit for your voltage before planning long runs. Press each LED bar into its driver until it clicks, and confirm it is fully seated. For denser flowering layouts the MB-9 adds a ninth position, while the MB-7 and MB-4 spread out further. The attached Model One manual shows the full layout and wiring diagrams.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eEight Driver Positions:\u003c\/strong\u003e Builds a 720W Model One fixture from eight 90W drivers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEven Spacing:\u003c\/strong\u003e Driver positions about 5.91 in apart keep coverage uniform.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCeiling or Unistrut:\u003c\/strong\u003e Hangs on the provided hangers or locks into standard Unistrut.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits TLD-2 and TLD-4:\u003c\/strong\u003e Works with both two-channel and four-channel Model One drivers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool-Light Install:\u003c\/strong\u003e Drivers twist onto the bar instead of being bolted up one at a time.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background-color:#333; color:#fff;\"\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003ePart number\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eMB-8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eDriver capacity\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e8 × TLD-2 or TLD-4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eTotal power\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e720W (8 × 90W)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eLength\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e44.57 in (1132 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eWidth\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2.21 in (56.1 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eDriver spacing\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e5.91 in (150 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eMounting\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eDirect hang or Unistrut\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1.92 lbs (870 g)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003ePackage contents\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1 × MB-8 mounting bar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"ThinkGrow","offers":[{"title":"Default Title","offer_id":50528181813462,"sku":"MB-8","price":23.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/thinkgrow-mb-8-main-v1.webp?v=1790264279","url":"https:\/\/growershouse.com\/products\/thinkgrow-quick-release-mounting-bar-for-8-drivers-720-watt-mb-8","provider":"GrowersHouse","version":"1.0","type":"link"}
