This study was conducted to evaluated the effect of LED fixture spacing on the vegetative growth, reproductive development, yield, and water-soluble vitamin contents of greenhouse-cultivated paprika ( Capsicum annuum L.) to address yield and quality limitations caused by severe light deficits during winter. Treatments included a control with no supplemental lighting and LED fixtures spaced at 2.5 m or 3 m. The 2.5 m treatment led to shorter plants smaller leaves than the 3m treatment and control. However, the number of leaves increased, maintaining the total leaf area. In addition, this treatment significantly promoted reproductive growth, as evidenced by the increased flowering node position and fruit set per plant. During the 20-week harvest period, the 2.5 m LED spacing resulted in the highest cumulative fruit number, fruit yield per plant, and total yield per unit area (51.6 ton·ha-1), while maintaining individual fruit weight. Analysis of water-soluble vitamin content revealed that fruits from the 2.5 m treatment contained the highest levels of vitamins B₂ and B₅, In contrast, vitamins B₁, B₉, and C were relatively higher in the non-lighted control, indicating differential responses among vitamin types to supplemental lighting distance. Collectively, these results suggest that sapcing LED fixtures at 2.5 m intervals is a practical guideline for optimizing light use efficiency, enhancing stable productivity, and improving the nutritional quality of paprika under winter greenhouse conditions
