I brought the "warm white" set in an offer, almost half the price and I am happy. There is a sticking tape in the back of the strip for easy installation. I have experiment with the included power supply; here some numbers (see also photos). Power supply without load: 13,04 V (Take into account than i have the EU/230V version). With all the strip (5m): 9,18V * 0,214A = 1,97 W With 1m (60 LEDs): 9,54V * 0,098A = 0,935 W Conclusion: you can certainly drive all the 5m with this power supply because the LEDs are actually under powered. This is good because you don't have any way to dissipate the heat so you can use them anywhere as it is, without any problem of burning the power supply or requirement for cooling. Off course you have a bit less lumens this way, but this is a balanced trade-off. You can drive these LEDs "hard" to get more lumens but you need a way to dissipate heat (like "Aluminum Channel Holder for LED Strip") and another power supply (i strongly recommend a power supply with adjustable current). Make sure than you know what you are doing because a very small increase of voltage can actually produce a much higher current and you can easily "fry" the LEDs (search for "led forward voltage" for more info).
