If you are looking for a nice fixture that will stay cool, look nice in a office setup on that tank, I would recommend looking at freshwater LED fixtures from Current USA and finnex. I use them myself and have found that they were the best light sources for all kinds of plants .. VFTs, cephs, nepenthes, utrics, sphagnum etc. They might cost a bit more than the regular LEDs, but IMO if you are seeking for a clean setup, they are totally worth it.
