I use Mars-Hydro in my tent. I don’t know if it is any better than any other, but I am pleased with them, and added a smaller supplemental unit when I upgraded to a larger tent.
If I am reading your question correctly you are exploring light options which includes cost. You have your budget amount, and that is a great one, depending on your tent size or the area you are lighting. So first, you need to figure out the area you are lighting and how much wattage you need to cover that. I had to add another 1000W to the 3000W I had when I went from a 3x4 to a 5x5 tent.
Your next thing to decide is whether you want LED, flourescent, or HPS (high pressure sodium) aka HID (high intensity discharge). There are pros and cons of each and you can do a search and decide which works for your situation.
Fyi, I want to say overall the cost for me to run a 5x5 tent with the two lights and Cloudline exhaust system, plus air pump, water pump, and fans, is around an extra $75-100 a month in electricy. We are on a water well, so don’t pay for water, but I use hydro and dont use a lot of water.
