Got these ones from eBay.....really adds more flexibility when it comes to mounting the LED's.

Fired up for some tests and I'm pleased with the colour, and a big improvement from the 50:50 Cree's used previously. All I need to do is find the right settings that will allow me to take some pictures of the tank and fixture at the same time.

All of the pics are either overexposing the fixture or underexposing the tank, not to mention the white balance.

Here is the MDF version before I tear it all down again to start on the acrylic.











I've managed to clear up a lot of room mounting everything into the fixture, and eliminated a few power cords as well. The fixture will have a standard C-13/C-14 connection, but I will need to order a locking cord to prevent an unintentional dip in the tank.

The cooling fans are shutting off after several minutes of running and I've identified the relay as the cause of the problem. The vendor is sending a replacement at the moment since this is a rare occasion where I only ordered a single unit. I'm hoping that it is just a faulty relay. Still waiting on what I'll be using for moonlights to arrive as well.

The 2x4 sand will not be in the final design...will be working on some mounting brackets, and maybe a hanging kit....still haven't decided.

Nice
Are you making the whole works with acrylic, or just some parts ?

Hi greg....top and bottom for sure, but still undecided regarding the sides.

Something like this



or this

[gregzz4]

Hmm, aluminum or oak
Either would look very nice. I like the idea of it being recessed into the edging.
Get on it, we want to see
If you decide to make the top of the fixture really flush, these PC fan grilles catch lots of dust and then you just vacuum them off
I run them on my office tower and they don't create extra noise, even at 1600rpm

[gregzz4]

I shoulda mentioned ...
These grilles/filters go between the fan and acrylic so all you see is the dome
The holes are about 1.5mm. Avoid the ones with larger holes as you will get noise

How's the wood holding up? Mdf is probably the worse type to use near any water as it absorbs moisture and expand. Great looking top btw
