I feel like I'm flying solo on the lighting part of this. I live in Central Texas and away from monthly meeting of the DFWAPC. I don't have a chance to compare notes with others on these issues and am instead relying upon input on this forum and one other (no responses from the other). I miss the comraderie and sharing of information from those meetings long past.
Thankfully, the internet (overall) has been a Godsend on gathering information as well, but it is a challenge to sort through opinions. I get the sense that the vast majority of us are feeling our way in the dark on lighting issues with LEDs being newly explored and older, more reliable types of lighting, being eventually phased out.
I suppose I'm going to make my share of mistakes along the way in this project. I guess this is okay because it is how we learn. Unfortunately, with such a large aquarium, each of these lessons will cost me $$$. Since I've been dreaming about this tank for basically most of my life, I really don't mind though. It's all part of the journey. On the other hand, I've done so much tinkering, and planning, and research on this over the years, that I've become supersaturated with it all. I now have a window of financial opportunity to purchase the tank in the summer months.
Right now, lighting issues are my concentration though.
I've purchased some relatively inexpensive LEDs in a lot of 10 from China. They should arrive in a few days. The chips are genuine CREE. The specs on bulbs from sites like what is linked below are frustrating to deal with because there will be conflicting information on the same page. Here's what I ordered (specifically e26, 110V, 5500-6500K, 60 degree: http://www.dhgate.com/10pcs-lot-high...dab6d2ade.html
I am also going to order some CFLs: https://1000bulbs.com/product/6840/FC09-MS65.html
The end product might include both types of bulbs or perhaps just one.
I've also ordered two more Ikea lamps, so I will have 10 now.
As far as lighting goes, I'm treating the aquarium loosely as a series of 10 gallon tanks that will house low light plants.
