Most modern LED bulb replacements -- including yours -- produce slightly less light than the incandescent bulbs they were meant to replace. A few, like my V-LEDS panels, produce just slightly more usable light. So it's a one-for-one replacement.
We have fourteen lights
in our 5th wheel trailer . . . all of them LEDs. They cost a bundle, but having them allows us to dry camp with our solar
panels and not worry about power consumption. Of those fourteen lights
, however, we've found there are just seven that get regular use: The one by the door, the one in the washroom, two in the kitchen (one over each side), the light over the dinette and the two "reading lights" over the dinette. You probably have most- and least-used lights
in your trailer, too; if you're trying to keep costs down, you might stop and think which lights you turn on most often, and replace those bulbs first. That way you get the biggest energy-saving-bang for your buck.
