V4 / SV4 (OLD Series)

V4 and SV4 LED kits (also manufactured as F2 LED Series) use CREE LED chips, and are now a very old LED series. New LED series such as X9S, F5, F6, R8, and GTS Pro (2022), X20 (2023), R8 Pro (2024), R7/R7 Pro and WS45 (2005), all surpass V4 and SV4's specs and provide way more light output.
