Osram Lightify Gardenspot Mini RGB has, as its name says, only RGB leds so no W led to bring adjustable color temperatures and good CRI's.
Gardenspot RGB has almost the same gamut than Flex RGBW.
The primaries I picked were :
Because these RGB leds create the white color combined, don't expect great CRI's. That spectrum means if you have in your garden a color of wavelength 580nm(orange), it is not shown properly because there's no light in that wavelength. It can create a light that shows in your eyes as orange but if you have something that is that pure 580nm wavelength orange, it does not get illuminated in these lights. These lights are only meant for outside effect light use.
