This study was conducted to investigate the yield of fruits and changes in internal and external quality, and to select an economical and effective light source. Sunlight was set as a control, and lights were supplemented on the upper canopy of cherry tomatoes (Solanum lycopersicum var.cerasiforme) using white and QD-LED. The supplemental light through the artificial light source increased the light intensity by 45.4% on average compared to the control, and the Fv/Fm increased by 9.2%. There was a difference in light quality as well as a change in light intensity, and it was found that the QD-LED with the highest a*/b* value progressed faster at the breaking stage and the maturation period was greatly shortened compared to that of White-LED and the control. The supplemental lighting treated group showed higher values than the control group for length, width, number of fruit, and weight of cluster, and among them, QD-LED showed the highest value. The QD-LED, which matured tomatoes the fastest within the same period, resulted in the highest soluble solids and the lowest titratable acidity and firmness. For DPPH radical scavenging activity and ascorbic acid, the supplemental lighting treatment showed higher values than the control group, and QD-LED showed better effects than White-LED in the supplemental lighting treatment. Additionally, the malformed fruit incidence rates were the lowest in QD-LED. Considering the economical aspect of both light sources, the QD-LED showed a relatively lower electrical power consumption, lower cost, and a much higher energy use efficiency than White-LED. We conclude that supplemental lightning on the upper canopy of cherry tomatoes is effective and QD-LED is the most suitable for use.
