This review for the linked led strip is interesting:<p><i>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&#x2F;watt, so this strip is outputting at most ~3630 lumens. Seller&#x27;s description of &quot;45-50LM&quot; per LED would lead you to believe this can output 15000 lumens or ~454 lumens&#x2F;watt. This is far outside the world record 200 lumens&#x2F;watt bulbs and even outside the theoretical physical limit of 250–370 lm&#x2F;W.</i>
