MH obsolete?

Obsolete? No...not yet but it is on its deathbed.

The issue I take with the "replicate spectrum under water at a specific depth" concept is that nobody keeps coral species found only at a specific depth, nor do many corals only reside at a specific depth. Once you try to nail down a light spectrum for 50 feet, you're running into the same "Problem" as a metal halide or any bulb. It's just not really a problem that needs solving. The best tanks from the past 20 years had fixed light spectrums that were inappropriate for a lot of what corals naturally may receive in the wild. Controllability over each individual wavelength is a parlor trick. It's cool, but it's mostly for the reefers entertainment or the tech geek side of all of us. Otherwise those tanks packed with all manner of deep and shallow water corals grown under 6500k halides and VHO tanks wouldn't have worked. It's a nuke the city to kill a few bad guys approach. It works. Any tinkering is just for "fun". If you find that fun.

Very true. I have no clue what my LED color temp is, nor am I worried. I like it, my wife likes it and my corals grow under it so all is good.

I'll drink to that.

Ok, replacate was a bad choice of words. It is more of a tinkering sort of thing. However the idea of changing the lighting by utilizing a remote, phone ap, program ect. Is a lot more apealing than buying bulbs, changing around fixtures in a hood . So yes its a tinkering thing.

I remember when people were trying to see what could grow under T5 lighting. A lot of people assumed it wouldn't be as good as VHO, thinking it was more like CF... and certainty wouldn't grow SPS..

Now nobody runs VHO, and few run CF.. Either T5, MH or LED. Can the hobby support 3 different types of lighting? I believe so, historically it has. Will LED kill T5 and MH just as T5 killed VHO and CF? I'm doubtful, a lot of people don't like the way LED's look or the light coverage. It isn't a "no brainer" kind of switch like T5 was. (Although CF still exists, mostly for it's lower cost)

I'm going back to VHO actinic supplementation after a 5-6 year hiatus.

This is what Started this thread. Anyone using these lights? www.giesemann.de.

Of course I'm talking about the LED Lights. Bluetooth feature is nice.
