White light generated by mixing the red, green, and blue laser diodes (RGB LDs) for simultaneous high-speed underwater wireless optical communication (UWOC) high-efficiency solid-state lighting (SSL) was proposed demonstrated experimentally first time. The allowable maximum real-time data transmission rates of 3.2 Gbps, 3.4 3.1 Gbps RGB LDs with corresponding BERs 3.6 × 10-3, 3.5 10-3 3.7 were obtained at a 2.3 m distance using an on-off keying (OOK) modulation scheme, respectively. And UWOC aggregate rate 9.7 achieved based on LDs-based wavelength-division multiplexing (WDM) UWOC. Moreover, SSL mixed white investigated different scenarios over link m. light-based system without diffusers yielded 8.7 Commission International de l'Eclairage coordinates (CIE) (0.3154, 0.3354), correlated color temperature 6322 K, rendering index 69.3 illuminance 7084 lux. Furthermore, employed to provide large-area SSL. line circle implemented 5.9 6.6 CIE (0.3183, 0.3269) (0.3298, 0.3390), This work suggests potential applications in white-light
