Ok, So good morning, first post yadda yadda yadda...

I've been using the search function and can't find anything.

I've read the stickys and can't find anything.

I want to build one of these. I found a light on amazon that is IP67 rated. It looks to avoid the issues in the "LED light warning" thread. I'm curious, as it is not hermetically sealed, what the gurus have to say about it's viability in an undertand/over sump type setup. Here is a link to the light:

if anyone has a thread from the past that discusses waterproofing in greater depth than the sticky that would be appreciated. I can't find anything regarding the ratings, I would assume that the ratings are relevant when discussing lighting in this type of climate, but only to a certain extent. It IS saltwater, so...yeah...

My other thought is the small cluster being a hindrance to the spread of the light and it's capability to cover the entire surface of the mat. That being said, we're not talking about a huge tank or a heavily fed tank. I'm at one cube a day (admittedly, likely overfeeding), and once i get to full stocking don't see myself going higher than 3 per day. However, that's just a rough guesstimate and may build a 4 cube size scrubber.

Which brings up another question: Is there a such thing as "too much" scrubber? I assume not but i want to check to be sure.

Just some random thoughts...

p.s. I'm a chronic over-thinker and i have yet to find the appropriate support group.
