Yea aesthetics is an issue....and the hodge podge of different lights.
Your tank is narrow AFAICT (12"?) so you have an issue raising lights and having a pair since there is a fair amount of gap beteen the now 2 rows of diodes..
There is a V2 of the pro using 660nm reds, slightly higher power and 90 degree lenses..
@ 6" your diodes are spreading out in a dia. of about 20"
10" each side..plus "gap"..point isyou can lose a lot of light w/ 2 if not set properly..
tilting them in is an idea but a pia..
I'm sort of surprised one isn't enough though.
Yes, tank is about 12 inches. That is actually a concern because the spread visually (or lack of it) is fairly noticeable just moving the light. If in back, the front is noticeably dimmer, and vice versa. More so, I have never had a light where plants shade the bottom so much, so adding anything new almost requires me to cut everything else down or it will be shaded.
I wasn't sure if a second light would help this, or just spread the light outside of the tank. I haven't seen a lot of scientific tests on this light, despite the fact everyone was using this on this size tank 3-4 years ago when I bought it. Going through journals, I see that most of the red plants used that made me feel the light would be enough are plants that color easily (which I am experiencing great reds on certain plants). They have far from the plant mass and shading. It seems in what little I can find is that par is almost half on the sides of the tank if the light is in the middle.
One works fine in the right circumstances, and I have no trouble growing plants, it just isn't something I can get great color until at the top, or the plants are right below (4-8 inches). So, I have to choose my battle with which plants get the best color by light position on the tank.
I've got two of them I'll sell you cheap if you want.
They were not cutting it for me on my tank. 24x18x18
If it were me though I'd get the Twinstar S...
Do you care to elaborate? Where you running both on that tank? How long was your photoperiod? What intensity?
I was considering a second light as a cheap upgrade but it sounds that I may be going down the wrong path. How does one Twinstar S compare to two of these, if you had them on the same tank.
Furthermore: I can by most Twinstar products locally, one reason I am interested in that brand. I also can get UNS locally in the future, the Titan 1 seems interesting, but at that price, it seems to have some issues I am not fond of (hot, concerns of failure, light spillage, color not as good as cheaper lights, lack of flexibility). ADA lights are also available to me locally but I am not sold on the Aquasky design, which is the only light I would consider from them due to price point.
I am not opposed to buying elsewhere but being in the heart of the Bay Area, CA, I really struggle to support a company like Amazon over the stores I actually rely on.
