^You're talking about dream machines?
Invented by Brion Gysin?
...just looking at the link, I see that the OP is not, though i am pretty certain that is what phuckingnutz is referring to;
The theory is that at the right RPM, the flickering light can trigger certain brain waves to trigger "visions" or dreamlike CEVs.
There is a book - and a film - called "flicker" which goes on about this device at length.
From Wikipedia page;
A dreamachine is "viewed" with the eyes closed: the pulsating light stimulates the optical nerve and alters the brain's electrical oscillations. The user experiences increasingly bright, complex patterns of color behind their closed eyelids. The patterns become shapes and symbols, swirling around, until the user feels surrounded by colors. It is claimed that using a dreamachine allows one to enter a hypnagogic state.[4] This experience may sometimes be quite intense, but to escape from it, one needs only to open one's eyes.[1]

While I must admit I find the "vision inducing" premise to be flawed (with the "dream machine" anyway) they are fascinating and awesome for a bunch of reasons.
Firstly, they were referred to at the time of invention as something to the effect of "the ultimate (ie final) piece of art " because it is intended to be viewed with ones' eyes
closed (!)
That is pretty cool - and hilarious. The people that pioneered such things (Gysin, William Burroughs) were taking a lot of Moroccan hash, among other things.
Their effect is something akin to a gentle, multi-textured strobe light. I have had dmt and shroom trips in a room with a dream machine and a bunch of mirrors in it, which created something like a sea of moving light sliding around the room at an even pace. I find as background light - for a trip, playing music or as onstage lighting when my band play, they create a calming, trippy ambience - in much the same way as a flickering open fire.
In that sense (and I believe this is mentioned in the book and film about dream machines) there is something about the effect created that is comforting and goes back further into human pre-history than almost any other universal experience - that of sitting around a fire at night.
Apologies for not referring to the product in question, OP , but it seems to rely on much the same principle as the dream machine.
I find such lighting
absolutely psychedelic - but not in the sense that it induces any sort of altered state (unless you are susceptible to epileptic fits such as those induced by strobe lights.
I find such lighting to be incredibly synergistic with psychedelics (from memory I have taken shrooms, dmt, LSD and 2c-D in a room with a dream machine running.
Any feelings of altered consciousness I now get from contact with this device is clearly tied in with memories of the experiences I had whilst tripping in that environment - on their own, I have had no incredible experiences using dream machines to induce "waking dreams" but I do find the lighting they produce incredibly stimulating in the midst of a psychedelic experience.
