Researchers report approximately 40% yield win from using LED lights[1]. They are also much more energy-efficient than other kinds of lighting.
Plants need a mixture of blue (wavelength of 458nm) and red lights (wavelength of 640nm), at a ratio of about two red LEDs to each blue LED. You can buy LED grow panels, but it should be much cheaper to just get bulk LEDs from Alibaba or a similar site. We need to research this.
