I've used a light and sound device since 1992. My original only had red LED. I replaced it with a Proteus last year. I just like to use it alone or with paraliminals from time to time. It works well with the paraliminals yet the paraliminals really don't require it.
I've never seen it necessary to use paraliminals with the sedona tapes. In fact after the first listening I found them much more practical in the car than in a trance state.
You could bypass the sound entrainmemt and add the light glasses for the Centerpointe CD I certainly wouldn't combine the sound with the centerpointe one I believe that combining it with different entrainment would defeat the purpose of the centerpointe on. Adding the lights would enclose the world for you while listening. However light entrainment also causes different brainwave patterns and in some cases is stronger.
If they have an impact on learning or not I cannot really say. They do make it more enjoyable and it certainly seems to stick. The relaxation aspects helps learning naturally enough. However some people may find the light distracting. The proteus allows you to dim the light to a comfortable level so if you can get it as a trail period it may be worth experimenting with.
