Mount it clear of standing water and allow airflow around the heatsink fins so it can shed heat during long lighting cycles.\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003cul\u003e\n\u003cli\u003eOutput settings: 250W \/ 400W \/ 600W \/ Boost\u003c\/li\u003e\n\u003cli\u003eLamp compatibility: HPS and MH, via standard IEC lamp socket\u003c\/li\u003e\n\u003cli\u003eIgnition: digital intelligent ignition with soft-start\u003c\/li\u003e\n\u003cli\u003eInterference: RF shielded\u003c\/li\u003e\n\u003cli\u003eHousing: finned aluminium, passive cooling\u003c\/li\u003e\n\u003cli\u003eVersion: Standard or Slimline (2026) casing — same electrical specification, redesigned enclosure with integrated IEC mains inlet\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"Maxibright","offers":[{"title":"Standard","offer_id":53798915211530,"sku":"LGT-MAX2-040-01","price":44.95,"currency_code":"GBP","in_stock":true},{"title":"Slimline 2026","offer_id":53798915244298,"sku":"LGT-MAX2-040-02","price":44.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/maxibright-varidrive-600w-dimmable-ballast-1.jpg?v=1790169765","url":"https:\/\/hydrocropshop.co.uk\/products\/maxibright-varidrive-600w-dimmable-ballast","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
