Hi all, really know nothing about LED strip but I need to buy 1 for my tv feature wall. plan to put it behind the feature wall L-shape (2.1m + 1.5m), so I plan to buy 4m length one Please enlighten me. the shop said I need driver too. 1 driver should be enough for L-shape they are giving me 3 option: 1. LED strip 14.4w per meter $18 x 4 m + 60w driver $40. total $112 2. LED strip 7.2w per meter $15 x 4m + 40w driver $30. total $90 3. LED strip RGB per meter $23 x4 + 60w driver -$40 + led 6 key controller RGB c/w remote control switch $60. total $192 is the quote too high or reasonable? I saw people selling 1 reel of 5 m only $50. Is it different type? What I need to ask them, the type maybe? for option 3, can choose different color anytime? what color combination possible, only can on 1 color at a time, right? sorry for lots of questions. really blur about this thanks
