ThinkGrow’s Model-W is a 630-watt, bar-style LED fixture built for high-PPFD vertical farming. It provides a balanced full spectrum for all stages plus an independent 730 nm far-red channel that can be timed for end-of-day or morphology effects when used with a TrolMaster Hydro-X and LMA-T. The system outputs over 1,600 µmol/s at greater than 2.6 µmol/J efficacy, with on-board dimming and group control. The 45 x 44.6 x 4.44 in form factor weighs 38.8 lb and is rated L90 >54,000 hours with a 5-year warranty. Autosensing 100–277 V input simplifies deployment. Typical flowering coverage is about 4.5 x 4.5 ft at mounting heights above 6 in. The fixture uses Samsung LM301B diodes and integrates readily into multi-rack canopies.
