PhotonTek SQ300W (2.7 umol/J) Voltage:120v A powder-coated steel grill andCompact LED for Tight Spaces: SQ300W Pro for 3x3 Footprints The fixture pulls 310 watts of full spectrum white, deep red 660nm, and far red 730nm diodes. They sit across a 22. 08 by 22. 08 inch square bar array. The PhotonTek SQ300W Pro LED produces 816 mol s PPF at 2. 7 mol J fixture efficacy. Independent tests measured peak PPFD near 1000 mol m at a 44 cm hang height. Mid 700 mol m readings appeared along the edges of the rated 3. 3 by 3. 3 ft
