Review on Illuminate Your Outdoors With URPOWER Solar Lights: Waterproof, Adjustable And Auto On/Off For Garden, Pathway And Pool - 4Pack Warm White Spotlight by Nate Skinner

Less than 2 weeks after I bought these, I saw Revain also sells Albrillo 5 LEDs solar cold white light version for about $1 more. I put this light and the 5LEDs light side by side in front of my house. So both should receive the same amount of Sun light. Here is what I observe:1) at Sun Set, this URPOWER 4LEDs warm white light would turn on later then the Albrillo 5 LEDs cold white. See picture which show two lights side by side2) we have plenty of Sun light where we live in the Summer. By about 2:00AM this 4LEDs want white light would turn off while the 5 LEDs cold white one still lighting. I know some light designs purposely turn off the batteries power to prevent draining the batteries out completely so the batteries won't be damage. But I don't know if this is the case or not. The 5LEDs light may just draining more out of the batteries or may just have better true capacity battery than this 4 LEDs. You can see the in pictures that this light turn off but the 5LEDs lights are still on3) There is not much different in brightness between the two different brightness modes. I can't tell the different myself. Either mode is not as bright as I need.So under the same charging condition, these 4LEDs warm white version would turn on after and total light up time is shorter than the new 5LEDs cold white version. It may be the light sensor sensibility and batteries turn on/off are different. I put two of these pointing toward the entrance of my house and they are not bright enough. So I put 5LEDs cold white next to each and still not as bright as I want.In the last picture, I compare the brightness to neighbor's much brighter normal electric lights.I used a big giant nail I bought from Home Depot to dig a hole first before I insert the light mounting pole to avoid damaging pole.
