BioBudsanswered grow question 4 years ago My friend is very happy with his Mars Hydro SP 3000, they are on sale now (at the .eu site they are) and set you back 369 EU / 280 US is the budget option that is a great performer, as a tip for more lifespan: put driver outside tent (they made them so they can) and put a fan on the lights. If you want to customize: HLG Quantum Boards, You can get three or four in a row, for 300 to 400 watt output. Spider Farmer is the other Chinese budget option. People have good results with those too.
I you want quality, durabillity, warranty etc, look for US or European made. Im eyeballing this: Easygrow S800 Pro, it would be great for your tent. They are a European supplier, but last I heard they had some problems with delivery so be carefull. What is awesome about that light is that its 3.0 Umol, .2 more than most brands. Loads of diodes but main thing for me: it has am optional controler that can dim and time but with sunrise and sunset feature for only 69 EU extra.
Make sure they are still in business though!
Happy hunting!
