Blinkstick Flex Brightnesss

I got a blinkstick flex which I was hoping to use for some undercabinet lighting. However even at full brightness, its not that bright. I have a non controllable USB white LED strip I plug into the same computer USB and it seems many times brighter which is what I was hoping to get out of these.

Is there anything I can do to make these brighter? USB 3 can go higher output current, so can I take advantage of that? Is it that these LEDs are diffusing too much and another more directional strip may work?
