about to order LEDs

[e46er]

so Im about to pull the trigger on some evergrow LED people seem to be happy with them and they fit my budget.

question I have is my tank is 4x2x2 with center brace.

should i go with 1 48" fixture with controller for sunrise sunset ect. for $615 with a total of 102 3W LED which is 2-6weeks backorder

or 2 smaller units for $199 that are not controllable just manual dimmers. but available right now http://www.reefsupplies.ca/online-st...-16-Light.html

the 2 smaller controllable lights are $355 each which for 2 is more than i want to spend.

Im leaning towards the single 48" fixture for astethics, cords, not sure if the ability to control is worth the extra 200 bucks or not but it seems most people go for multiple smaller units which i cant afford 2 controllable smaller units.

thoughts ?
