What a minute, shouldn't the specs be different for different lengths?
The circuit board within the casing of the controller at the start of the backlight will pull 5W, regardless of length. As you may assume, this means that an individual LED in the 1m backlight will be brighter than an individual LED in the 3m backlight. As a whole, the brightness of each backlight length is the same.
