Received my pair of Litom Solar Powered Motion Sensor Outdoor Lights, charged them in the sunlight on Saturday afternoon and Sunday (12+ hours).
… 

Each unit comes with an instruction manual, two mounting screws and two plastic anchors.
The output modes are as follows:
Mode Output
Off Off
1 Constant medium (50-60lm)
2 Standby Low (10lm) / High (150-170lm)*
3 Standby Off / High (150-170lm)*
* - Motion sensing modes
Mode 1 is a simple on at dusk, off at dawn operation (activated by photocell). It is bright enough to illuminate a footpath or building corner, but not much more.
Mode 2 is a motion-sensing mode. While at rest, it puts out a low beam of about 10 lumens. When activated, it puts out about 150 to 170 lumens. For my purposes, to mark my driveway endposts, this is ideal. Bright enough to see them, but not too bright as to be distracting to the neighbors.
Mode 3 is a motion-sensing mode. While at rest, it is completely dark. When activated, it puts out 150 to 170 lumens. Note: 150 to lumens is bright enough to illuminate a 30’ x 30’ area with night-adjusted vision, but not bright enough to substitute for patio lighting.
This is a picture of Mode 2 (Standby Low) on my endpost …………… and this is a reference shot showing the endpost:

Motion-Sensing
Motion-sensing is done by a Passive Infra-Red (PIR) system. It is sensitive to relative changes in infrared (heat) sources, like human bodies. When I tested it, it appeared to be sensitive up to 25 feet and within a cone of about 40 degrees (20 degrees on each side of center). And when activated, the high beam turns on for approximately 11-12 seconds before resuming its standby mode. If I stay motionless, the light remains in standby mode. Only if I move within its range am I detected. So, if I want the high beam to remain on, I have to keep moving.
Tint
The tint is a cool white. Not obnoxiously blue like some lights. I’d call it a 1B tint. I personally like neutral to warm tints, but I found the tint of this light to be reasonably good.
Other
It seems to be well manufactured. Fit and finish details appear to be first-rate. During installation, I accidentally dropped the unit from about 3-1/2 feet and it survived none the worse for wear.
I have not had an opportunity to see how well it performs overnight or during long periods of inclement weather.
Nor have I had a chance to test it for weatherproofing.
And only time will tell about its long term performance and durability.
But so far, so good.
