Dude you need to make a time lapse vid of that.
Anyone Thinking of Dumping LEDS and going back to Halides

something like...
dark
red
red and yellow
yellow
yellow and blue
blue
blue and UV

yellow and red

I might skip yellow since the MHs will do that fine.

A nice example of led use http://www.reefcentral.com/forums/showthread.php?p=20147169
Very nice set up, but again kind of proves the point some people are making about leds though, as you need complete coverage and wattage equal to or more than a decent metal halide set up.

T5HO and MH seem to mainly be more forgiving of mistakes and perhaps a lesser skill level of reef keeping. I now know several long time MH loyalists that did the LED switch about a year ago and have not missed a step in growth and color, but these people make no mistakes and have every other aspect of sps growing basically perfected. With bulbs you have a little more margin of error. I have anyway.

If you buy this fixture, you will be very disappointed.
These fixture only belong to trash piles.
First of all, their ballasts are very dim compare to any name brand fixture.
Second, they rust quickly.

You are simulate what you see on the beach, that is not what coral sees under water. Lol

This ones gone quiet
I came across the Phillips coralcare LED fixture recently, a light with scientific backing. A light which is tempting me to try LED again
What I can say is it has a lot of LEDs in the 420nm
40x 6500k
32 x RB
16 x 420
8 x PC-Amber
8x cyan
They found growth and color to be the same as T5, which is promising.
The lights give no shimmer and look more like T5 due to their frosted glass cover.
Anyone running these ?
Finally they eliminated the red led which can be harmful and useless.
Great to see them ditch the green led which is also useless.

Really?? Interesting because I snorkel at dawn, midday and dusk and I see that on the reef.
Nice to know your find other people's experiences funny... Lol

How deep do you snorkel?

no deeper than 8-10ft at most. The corals I see there are comparable to what I keep in my tank.
I wonder about wattage though, if u run 3w LEDs at 1w and have then layered out like Lani LEDs fixtures I'd say it is less than halide ? Watt for watt led is more efficient with the latest top end Cree LEDs yeh ? But with good reflectors and a fuller spectrum halides are proven and are probably close on par levels

I haven't seen a PAR map comparison of an LED and MH. I plan to do my own but always looking for other contributors.

Mh and T-5 went through similar realizations. Initially MH did not use reflectors and T-5 did not use enough lamps or reflectors. Both performed poorly until those issues got resolved. Not a surprise the LED is going through a similar growth.
