At this point I guess I would have to take the option you offer of disagreeing on a practical basis.

I think that it would be safe to say that about anyone, including Soundwave, can do a better job based upon lessons learned from this project.

Let's keep this "fun" and be helpful rather than judgmental.

1. Total LED count per 24" is not enough for high PAR.
Some people use 150 watt MH and others use 1,000 watt. It all depends on what you're trying to do and want to spend. "Not enough" is very subjective.

2. LED driver will not provide the current required.
See #1

3. Fan airflow should be perpendicular to heatsink cooling fins.
Yes, it could be more effective but it still gets the job done.

4. LEDs are can not be removed easily from heatsink.
See goofyreefer's point #4

5. Light must be placed close to the surface of the water because of the lack of optics.
Must? Should? Could? You pick. Early in engineering I did a lot on paper. Later I learned from a brilliant engineer that it's often better, when you can, to just try it out and see what works best. Soundwave can see what it looks like as he raises and lowers the fixture. Can you?

Now of course I'll have to confess to doing the same thing to your post that I'm complaining about you doing to Soundwave's design

Have fun

I guess some people are having a problem with the word "flawed" , OK , OK I will call them "engineering changes" .

I did post a build here several times a while back and if you click on my website you would see my build..... athough the information is outdated now I have had many engineering changes to it since.

I was hoping for lots of feedback on this but received little. Might be the reason I try to give more comments on soundwaves design.
