Undercabinet LED illumination

Undercabinet LED lighting has been rattling around my mind for a bit. Something a bit more uniform & dispersed than the stove lights might be nice. Toying with some LED strips recently had me thinking of this project. I wasn't certain as to what color or intensity might be best I opted for two different types in hopes that one would be good.

Two, 2 meter long strips were chosen -
(left of stove) $16 USB LED 5V SMD 5050 Warm White
(right of stove) $8 USB LED 5V SMD 3528 Soft Warm White

$2 USB power adapter from a surplus store (Casio CNRUSB 120vAC to 5vDC 1amp
$13 External switch "extension cord"

The 3528 / right of stove is the design I'd prefer - and might swap out at the left side. The illumination is perhaps a bit nicer though also the wiring was a tad easier - simple +/- connection where the left of stove had four connections +++/-. Not a big deal, but more time consuming when soldering connections. I could see buying pre-made connections if they aren't costly.

One of the strips. They come with a USB cable for power already connected. Plug it into a cell phone charger / power adapter - done. They are self adhesive. Time will tell if the adhesive stays put. Undercabinet surface cleaned prior.

Add in an external switch "extension cord" for control - the pieces are coming together.

Stick the 1/4" wide gridning stone for use in cutting a groove in the cabinet sides. Possibly not the choice should I do this again - too much smoke (read - smoke alarms loved me). Perhaps next time a circular saw, depth set as appropriate and making three or four quick passes to make the groove.

Two strips connected to wiring. One strip "stuck" to the cabinet.

Original - high intensity
Two incandescent appliance bulbs - they're perhaps 15 or 40 watts, each.

New - LED's only
The right side looks significantly brighter in the photo but in reality it does not seem to have as large of a difference.
