So, I was having this problem a while back. Here is what I found after exhaustive research on LED lighting.
LED have a problem with temperature, that is to say that they get really hot, so, what I did was this:
I went onto Amazon and bought a little fan made by a company called AC Infinity. It was $18 for a little "muffin fan" (go to amazon and type in muffin fan and they come up first)and I just sit in on my H.O.B. filter and aim it at the lights and it keeps them cool. I also bought a little speed controller for it, too, and I put it to a timer that is the same time schedule as the light itself. It keeps 5 different LED lights cool to the touch. It uses less than 5W watts of power and it doesn't cool down the water either. I also have a tank with a pump in it, but, it doesn't produce any heat that I have noticed at all. Also, it looks like there is a little area in the front right that opens up to feed the fish? If so, you could set a fan on top of that with it open and the fan would suck out the heat. These little fans have a "mounting kit" that comes with them and you could actually screw it to the hood, that would be what I would do, if it was me. It seems to me that not having a hood on has helped a ton with the problem I was having. Might be worth a try? I have had one fish jump out over the last 3-4 years, but, I also have different fish than you. I can't tell what you have. If there is a vent on the hood, sitting the fan on top of it may help, too. I am not %100 sure of what the aesthetics you are going for because that is a personal thing that differs widely from person to person. I didn't mind getting rid of the hood, so, it wasn't a problem for me. Mine are also in the basement, so, they aren't ever seen by other people.
From what I could find out about LED lighting, I understood this, the LED's produce a lot of heat and that heat will eventually destroy the LED's. I have 5 lights on a single tank, but, they are all at about %50 or less. That way, they don't get too hot and die before their time. I spent about $30 to keep my $150 running as long as possible. Seemed like a good investment to me. I like the lighting aspect of planted tanks and I have done a lot of different experiments with different lighting styles. I keep my tanks at 77'ish and my house is at 68 degrees. The LED's don't seem to affect the water temperature too much and I have an open top on all my aquariums. As I said above, I keep the lights at %50 or less, but, I do realize that not everyone can afford to have multiple lights on their tanks and I would suggest to keep the lights at %75'ish, if you can. If you can afford it, I would get a couple lights on top and keep them all at %50'ish, but, I do understand not everyone can afford to do this. I consider lighting to be one of the most important aspect of planted tanks and I believe you shouldn't skimp on them if possible.
This is all just my opinion, though and I am SURE others will disagree with me. If you do, that's fine, just please don't be nasty about it. Thanks and good luck to all!
I am trying to add pics, but, I can't figure out how to do that, so, sorry. I think if you go to my page on here, there are pics of the whole aquarium and you might be able to see the fans, but, my pics are upside-down and it might be more trouble then it is worth.
Here are links to the fans that I bought:
Here is the speed controller for them:
I would get the smaller of the 2, the other is a little large for my tastes. These are really nice fans, imho. They seem like they are made solid and made well and it seems like they're made to last, too, but, it is ultimately your call. I don't know if you can find them much cheaper than this. You can get cheap Chinese ones, but, I know nothing about them, I won't pretend to be an expert on tiny fans. Type in DIY fans and a ton of them will come up. Gorgeous
tank, btw! Sorry, I rambled a lot in this post, but, I really
hope this helps! Good luck!
