My DIY ghetto-style lighting works for me because I don't have "display" tanks,
per se. Your stand looks like a DIY, so you could adapt some of my El Cheapo stuff by concealing it in hoods that match the stand.
This is a simple LED worklight, suspended from the ceiling above the tank on jackchain. It's easy to raise or lower by simple hooking the chain up shorter or longer. As a point source, it gives that wonderful shimmer effect; easy plants, like Swords, Hornwort, Duckweed, etc. grow very well under it, and by leaving it on for 10 or 12 hours straight, my Jelly Cat's home becomes a Hair Algae Farm. I harvest the stuff regularly and use it to feed my Goodeid livebearers; doesn't matter how much I throw in with them, it's always gone in a couple days. The tank/sump beneath the Cat's tank houses my Red Wolffish and also contains a Mattenfilter at one end...not visible as the bottom light, an actual aquarium fixture (!!!) is on blue mode only in this pic.
This is another DIY hack, an old fluorescent shoplight that has been gutted of its ballast, and now utilizes LED replacement tubes. Hung on a simple wooden frame attached to the tank stand. Easy plants grow well under this one as well, although this cool-water tank doesn't have any yet aside from some Duckweed. This one is timed to come on for 4 hours in the morning and another 4 in the evening, which helps control algae.
Both tanks appear dimly lit in these pics, mainly because I am too dumb to figure out the metering controls on my cell-phone camera and the glare from the fixtures overpowers the sensor, underexposing the rest of the pic. In reality, both tanks are very well lit. I usually hang a strip of cloth along the front of the shoplight, and around the front and sides of the worklight, to act as a shield to block out extraneous light which makes the tanks much easier to view; had them off as I was puttering in the tanks this morning and hadn't replaced them.
