This is a perfectly usable (and subjectively bright) LED strip, but beware, the specified lumens are a lie. My power meter reports a draw of 33W and another reviewer reports ~38.6W. The maximum efficiency of a 5730 SMD LED is ~110 lumens/watt, so this strip is outputting at most ~3630 lumens. Seller's description of "45-50LM" per LED would lead you to believe this can output 15000 lumens or ~454 lumens/watt. This is far outside the world record 200 lumens/watt bulbs and even outside the theoretical physical limit of 250–370 lm/W.
> http://electronics.stackexchange.com/questions/51778/ suggests that these LED strips have to be overvolted and powered at multiple points, which might bring them closer to ~7000 lumens.
> I'm also going to try comparing the hkbayi Super Bright to LEDMO's strip with 600 LEDs: http://www.amazon.com/dp/B013C2U09S/
