Is there any real benefit to full spectrum lighting?

It should be simple to get the answer instead of debate this some years more ,we just need a few people with big tanks that can tested it. One side of the tank full spectrum on side not,put the same frags on both side and then compare the weight growth and color.
So some volunteers?

Perhaps BRS can setup several cubes this way no light shed affecting the results.

Exactly - where should the extra photons come from?

Sincerely Lasse
Unfortunately the blue heavy proponents fail to grasp that concept when they start trying to push the blue spectrum is natural for how reefs look in the wild.

They believe that strong blue light is what coral live in in the wild so is their preferred spectrum. Show them pics or videos of how actual wild reefs look, and they claim it's camera lights, filters ect ect. Or the coral are living in conditions that are not optimal for them, even though those conditions are exactly what the corals chose to live in.

That will only show growth, not choice.

What’s the point? Use a quality light source that provides the look you like and a sufficient intensity for the corals you want to keep. As long as it’s reasonable and stable, the corals will adjust and do just fine. Then move on to more important issues like nutrition and flow.

At the end of the day if a newbie asks me the question of whether they need full spectrum or not I would say "pick whatever looks best"

Mine is white during the day and blue in the morning and evening. Works for me. If you want your tank to showcase fluorescence then good. It certainly won't kill anything to do so.

Issue I have is so many push the blue spectrum is natural lie to newbies that don't know any better. It wasn't until the advent of atintic vho that people first realized corals fluorescence in crazy neon colors was even possible. Then when leds cam out they found out heavy blue leds triggered a similar effect. That is why blue heavy id a thing, not corals preferences or health

Well who's in charge anyways?

Your assumption that corals can't be healthy with heavy blues is at best unproven.

Maybe less healthy (how the heck do you judge that) maybe slower growth ( is just that, slower growth) but not unhealthy.

So stick a 6500k metal halide over it and look at a yellow tank that you can't stand the sight of. Gee what " fun"...

Sorry a bit sarcastic for effect.

If you want to get fancy pick specific corals and a depth and either build or find lights that emulate it.
Range is rather large.

Only assumptions I see being made is by you.
Tell me do you run heavy blue over your planted tanks?
