All detailed information of our ring lights can be found on our website under each items product page.
The main difference is that the GlowPRO 2 18" has built in adjustable temperature control (warm to white light) giving you colours in between and the Classic 19" will come with 2 filters (orange & white) which will need to be changed manually.
The 19" is also a little wider in size in comparison to the 18" however the light output is nearly the exact same. Both ring lights will come with an adjustable stand, phone/ camera mounts and mirror.
The 19" can be used without the filters as it is detachable and the lighting without the filters will give you images that are more crisp/ sharp whereas the 18" has built in filters which cannot be removed and the images will be more soft - it will depend on what outcome you are after.
The GlowPRO 3 Ring Light has all of the same functions as the GlowPRO 2 18" however it also has multi-coloured RGB lighting, a remote Control, an in-Built USB Port to charge your devices and can be battery powered.
