Take those lumen ratings for LEDs with a grain of salt. I converted my entire MH to LEDs about 2 years ago.
Read about it here. Most 48-3528 panels will NOT put out more light than an 1156 incandescent. If I were you, I'd go with 48-5050 panels (5050's put out about 2X the light output of 3528 LEDs). I used 48-5050 panels to replace my 1141 bulbs; they work well, but are just slightly brighter (and 1156's are already brighter than 1141's). Also keep in mind that the color temp affects brightness also; with warm white (+/-3500K) putting out less lumens than bright (daylight) white (+/-5500K).
