We chose these light strips, with plug-in AC transformers, versus battery-powered LEDs. Their 2700K color, "warm" white, mimics traditional incandescent bulbs; they're not blue-white or super-white. In the photos, the strips are on high brightness, with kitchen lights on & sun coming in the single window. Even set on medium brightness, they're quite adequate for working. The lower two brightness settings are for mood, not working.We have 3 upper cabinet groups, so we bought 3 kit sets, each with its own transformer, rather than trying to figure out how to bridge them into one plug-in transformer. The price is right to do it this way.Each kit came with lots of connectors & sticky pieces; we had lots of leftover parts & light strips. We installed two rows under each cabinet.Each strip is 20" long. So, for a, say, 50" run, you'd need 2.5 strips. But these come with 3-prong plug-in connectors soldered, male & female, soldered to the ends of each 20" strip. In this hypothetical case, you need to cut one 20" strip into about 10", then splice. The trick is to cut your 10" excess from the center of the strip, cutting on the cut marks on the strip (3 copper pads here). Then splice the two remaining ends, male & female, together to make a 10" piece. For splicing, see the next paragraph.I bought these splice connectors from Amazon, for strips that I had to shorten when a 20" strip was too long; they were super easy to use: https://www.amazon.com/gp/product/B0C6KW7TX7 RGBZONE 10Pcs 3 Pin 8mm LED Strip ConnectorsPROS:-- We have 3 remotes, as each kit comes with a remote controller. Each remote control works on all three kits, though you may have to be close and point to the receiver.-- Default motion detection works only in dim kitchen illumination. You can make motion detection work in daytime illumination by wrapping black electrical tape over the cluster of holes of the remote receiver. The remote receiver is permanently wired to the first 20" strip.-- Quite bright, even on medium brightness setting, but never harsh.CONS:-- The motion detection function can be set to either 20 seconds or 50 seconds. Keep moving nearby to keep them on. It would be nice to have a longer on-option with motion detection. Otherwise, use the timed function with the remote.-- You'll need to buy a package of splices if the default 20" pieces won't work for you.(We initially bought a different brand & style, which were not nearly bright enough; worse, we needed 10 of those, each of which required 4 batteries. That would have been 40 batteries! Returned.)
