It throws out the typical cool blue MH spectrum that drives tight, sturdy vegetative growth and clean cuttings. When you're ready to flip to flower, just unscrew it, swap in a 600W HPS lamp, and the same ballast keeps doing its job. One ballast, two phases, no double-up on hardware or shelf space.\u003c\/p\u003e\n\n  \u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(200px, 1fr)); gap: 1rem; margin-bottom: 2rem;\"\u003e\n    \u003cdiv style=\"background: #f4f9f4; border-left: 4px solid #2e5e2e; padding: 1rem 1.2rem; border-radius: 6px;\"\u003e\n      \u003cstrong style=\"display: block; margin-bottom: 0.3rem; color: #2e5e2e;\"\u003eRuns on HPS Ballast\u003c\/strong\u003e\n      \u003cspan style=\"font-size: 0.9rem; color: #444;\"\u003eNo separate MH ballast required — works with magnetic or digital HPS ballasts you already own.\u003c\/span\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"background: #f4f9f4; border-left: 4px solid #2e5e2e; padding: 1rem 1.2rem; border-radius: 6px;\"\u003e\n      \u003cstrong style=\"display: block; margin-bottom: 0.3rem; color: #2e5e2e;\"\u003eCool Blue Veg Spectrum\u003c\/strong\u003e\n      \u003cspan style=\"font-size: 0.9rem; color: #444;\"\u003eClassic Metal Halide output that pushes thick stems, tight nodes, and dense vegetative growth.\u003c\/span\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"background: #f4f9f4; border-left: 4px solid #2e5e2e; padding: 1rem 1.2rem; border-radius: 6px;\"\u003e\n      \u003cstrong style=\"display: block; margin-bottom: 0.3rem; color: #2e5e2e;\"\u003eSaves Space and Cash\u003c\/strong\u003e\n      \u003cspan style=\"font-size: 0.9rem; color: #444;\"\u003eOne ballast covers your full grow cycle — veg with the MH, flower with a HPS swap.\u003c\/span\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"background: #f4f9f4; border-left: 4px solid #2e5e2e; padding: 1rem 1.2rem; border-radius: 6px;\"\u003e\n      \u003cstrong style=\"display: block; margin-bottom: 0.3rem; color: #2e5e2e;\"\u003eEasy Phase Switch\u003c\/strong\u003e\n      \u003cspan style=\"font-size: 0.9rem; color: #444;\"\u003eWhen veg's done, unscrew the MH, screw in a HPS, and the ballast handles the rest.\u003c\/span\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003ch2 style=\"font-size: 1.1rem; font-weight: 700; border-bottom: 2px solid #2e5e2e; padding-bottom: 0.4rem; margin-bottom: 1rem;\"\u003eSpecifications\u003c\/h2\u003e\n  \u003cdiv style=\"display: grid; grid-template-columns: 1fr 1fr; gap: 0.5rem 2rem; margin-bottom: 2rem; font-size: 0.95rem;\"\u003e\n    \u003cdiv\u003e\n\u003cstrong\u003eWattage:\u003c\/strong\u003e 600W\u003c\/div\u003e\n    \u003cdiv\u003e\n\u003cstrong\u003eLamp Type:\u003c\/strong\u003e Metal Halide (Retrofit \/ Conversion)\u003c\/div\u003e\n    \u003cdiv\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Single-Ended (SE)\u003c\/div\u003e\n    \u003cdiv\u003e\n\u003cstrong\u003eSpectrum:\u003c\/strong\u003e Cool blue (vegetative)\u003c\/div\u003e\n    \u003cdiv\u003e\n\u003cstrong\u003eBallast Compatibility:\u003c\/strong\u003e 600W HPS magnetic or digital\u003c\/div\u003e\n    \u003cdiv\u003e\n\u003cstrong\u003eBest Used For:\u003c\/strong\u003e Cuttings, propagation, vegetative growth\u003c\/div\u003e\n    \u003cdiv\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Cultiv8\u003c\/div\u003e\n    \u003cdiv\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Distributed in Australia\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv style=\"background: #fff8e1; border-left: 4px solid #f9a825; padding: 1rem 1.3rem; border-radius: 6px; margin-bottom: 2rem;\"\u003e\n    \u003cstrong style=\"color: #e65100; display: block; margin-bottom: 0.5rem;\"\u003eHeads Up — Lamp Care Basics\u003c\/strong\u003e\n    \u003cul style=\"margin: 0 0 0 1.2rem; padding: 0; font-size: 0.93rem; line-height: 1.7;\"\u003e\n      \u003cli\u003eAllow up to 15 minutes for full warm-up — MH lamps don't hit peak output the moment they fire.\u003c\/li\u003e\n      \u003cli\u003eNever restart a hot lamp.
