Like mentioned above, lights doesn't sound enough lights. Before you invest in a bracket make sure you can use it if you need to change fixture or different lightings. My tank is against the wall, I used a wall bracket to hang my lights and it doesn't put any weight or pressure on the tank itself. I hang the bracket little higher and I use adjustable cable to adjust the lights. For me, it's very important that I can adjust the lights higher or lower, that way you can adjust it depends n your plants need.
