A: Answer The starter kits come with a single controller and the controller can have up to 10 strips on it. If you get the one from BestBuy that has 3 strips then you can add 7 more. Each strip can output 700 lumens but the total lumens for all connected strips maxes out at 2800 lumens so every strip after 4 diminishes the individual brightness of each strip but the total brightness will still be 2800 lumens. If you want to keep them at the maximum brightness of 700 lumens per strip then you need to buy additional controllers and put no more than 4 strips on a controller. They are very bright though and so unless you need that maximum brightness you might try just adding strips up to 10 and only purchase additional controllers if you feel you need them to be brighter. I just ended up buying 4 starter kits with 1 controller and 3 strips in each kit so I have 4 controllers and 12 strips. That way I have a lot of flexibility and I can always add additional strips if needed.
