It's available in a variety of output densities. Plus, as you point out, you can always use a lot of it. :-)
Here's a 40 breeder I use for growing out viv plants; it's lit with 8 strips of SMD 5050 LEDS (5 cool white, 3 warm white) -
There are more efficient options, but not many that lend themselves as nicely to low profile lighting. I've got plants growing under flexible LED strips, plus I also have some of the screw in LED units like yours, and some "reef-style" DIY units.
It's all good, and it can all be made to work, depending on what your application is.
