I recently switched from metal halides 150 x 2 on a 100 gallon tank. My leds do not dim,so my question is how far above the water should i have these to acclimate my corals? I am using the Orphec pr-156w x 2 above the tank.

I'd suggest get them REALLY high, run a very minimal light cycle, and add some "window screen" in layers. Remove a layer every week or so and then after all the screen is gone slowly lower the light closer to the tank surface. Once the fixture is your desired height then start to slow increase photo-period to something similar to what it was before the LED.
I can assure you that just going with one of the above methods is only partially effective because LED is so much more intense than other lights alternatives over your tank. Go slow so your don't burn

Thanks. I have been watching corals and a couple of them not looking the same so i raised fixture to about 20 inches above tank. I also have been running a photopperiod of about 4 hours a day. These Orphec leds are way more intense than my halides.

WINNING!
Whoever she is? That's the owner's wife of this site..
mine were DIY LED's and I switched from a 2 bulb T5, so my situation is much much different. But I had mine mounted in a fixed position height above the tank, ran 4 hours blue 1 hour white, increased 1 hour of each every week on the dot until I hit 13 hours blue 8 hours white. Worked perfect, didnt lose 1 coral, didnt have 1 thing bleach or get mad at me.
O and the window screen type idea, or I have seen some people use eggcrates stacked up, anything that diffuses light in layers work, then slowly take the layers off. IDK if that appropriate for your situation but I asked this very same question 6 months ago and a lot of people said that was the best way.

It is hard to believe how intense these leds are. They don't look any brighter than the metal halides but wow they light up my whole living room. I will have to be patient and acclimate . Have way too money invested to burn down my corals. Thanks for all the replies.
as im sure you have read / will read, nothing in this hobby thats good happens fast. I am literally one of the most impatient people I know, but somehow I have managed , good luck!
, good luck!
