2 Examples of InnerQuest Lightframes

Back in the late 1980’s and early 1990’s IQ International, also known as InnerQuest, manufactured some excellent light and sound mind machines. Of course the available technology was primitive compared with today, plus at the time red LEDs for light frames was the first and only choice for the light stimulation. Of course all that changed, but here are two pictures of IQ International light frames that were common…

Notice the two LED positioning of the light frame on top and the ‘light intensity wheel’ for adjusting the brightness for the light frames on the bottom. The top light frame was used with the IQ 9110 and the light frame with the light intensity wheel was used with the IQ Jr light and sound brainwave frequency mind machine.
