power in this LED

xaflatoonx · 12/03/2014, 12:13 PM

My tank is a standard 90G.

49 x 19 x 26 = LxDxH

I got two Marine USA LED lights 48-60"
so essentially i really dont extend them - they cover the full area across.

Question is - how do i calculate how much power do i have in the tank?

I wanted to buy a clamp and the store guy was asking how much light do i get at the bottom and i had no idea.
This may be something i should have researched when i was getting them - but oh well.

Can someone please guide me a little on how to calculate the intensity i am getting in the different levels of the tank?

thank you for your help.

"typically" in the reef world we would refer to the amount of "PAR"
http://en.wikipedia.org/wiki/Photosy...tive_radiation

Typically the manufacturers have a "chart" on their site/specs that may include this information.. Some manufacturers may over state this number drastically though and all sorts of other factors may influence it.

Anyone that REALLY "must" know would buy or rent a PAR meter.. They aren't cheap...
And many just rely on watching their corals and how they respond.. bleaching may equal too much light,etc...

current usa has one like this..

I'm not sure what a "clamp" is here as these lights seem to be more than what a typical "gooseneck clamp" may support and are intended to rest on the tank frame or could be "hung" with aircraft type cabling,etc...

I think he meant he wants to add a clam

Lol. Sorry about that. Yes. Wanted to add a clam and didn't know if I have sufficient light. What do you think?

Two of the 48-60 inch in a 90 gallon good enough for one clam?
