afs-60293	Särkkä, Liisa Elina; Jokinen, Kari; Ottosen, Carl-Otto; Kaukoranta, Timo	Effects of HPS and LED lighting on cucumber leaf photosynthesis, light quality penetration and temperature in the canopy, plant morphology and yield	2017	9	.pdf	application/pdf	6012	272	58	Light production efficien- cy is better in LED than for HPS lights (µmol PAR J-1 electricity) and their efficiency is increasing in contrast to HPS units (Ouzonis et al. 2015c, Pattison et al. 2016). Heat output relative to light output is higher in HPS than in LED lights and while HPS lights strongly radiate heat downward, most LED armatures lose convective heat upwards even though the light is focused on the plants.	cache/afs-60293.pdf	txt/afs-60293.txt
