It seems like a plus I suppose. I wanted to go Led because I basically had nothing invested yet (an old T5 double bulb). I see see why Chad was asking as far as a reason.
I have the Gen1 Radion I bought used. Love it.I can go to a Gen2 by buying some lenses for 30.00 and get 50% more penetration or so. That is a LOT easier than selling a unit and buying again. I can wait and go to a Pro later next spring while having the benefit of an improvement now over what I had.

As with other LED (benefit of a doubt) It is quite astonishing to change light spectrum within seconds and see in a flash a look amazingly different with just a teeny tiny change.

The human enjoyment of what I see is a huge plus while also giving the tank what it needs. I do not have a load tank of corals or any for that mater yet. so for now I have the versatility to have a system that auto starts the day very dimmly and goes through the dawn to dusk all by it self. I would think that living things in a tank have a harmony to an effect as such. I have no halide experience and presume they snap on or snap off with a timer. I like walking up to the tank and changing the mood slightly .

I may feel differently with coral reaction, but the corals I can buy local all have radions too. they are acclimated in a way. Upgrading I would think as a bonus and a side plus for many. This gives reason to buy sooner or you might wait for ever for the latest greatest... and never feel ready to jump in. Upgrade ability is a unique niche, Right?
