Lumen output for a new room
LED lamps are heat-sensitive, and have a high failure rate if confined in a fixture too small or with insufficient ventilation. Putting a large lamp in a small fixture will likely damage the lamp after a while, and possibly create a fire hazard (though the fixture itself might be designed to survive the higher heat output of incandescent lamps).

There are surface-mount LED light fixtures with built-in (non-replaceable) lamps of 2,700 lumnens and more, which might be a better choice. Also check the color temprature. The lamp referenced above is 5,000 K, a somewhat bluish-white. Other lamps have color temperatures from a reddish 3,000 K to actinic 6,000 K.
