I really like the angled sides which adds/extends the light coverage. These seem to be just right for my back porch light, which faces my neighbor's house. It gives off enough lite, to a wider area - but I don't have to worry about the neighbors complaining that it is too bright at nite. Disturbing them as they try to sleep.We have an abundance of outdoor cats, raccoons, possums, & who knows what else that come out at nite as we have a creek behind our - very dark at nite & very large- properties.The wild animals causing much damage to my garage...& attempting to intimidate my 1/2 feral cats who faced down a far more dangerous animal, 5x its size ?.After discovering a litter of coons in my garage rafters, then a large hole dug under said garage (big enough to accommodate multiple species in what is likely a very large maze of tunnels/dens), I purchased many styles of solar lights to work with my sec cam system. This enables me to be able to track activities in my large, very dark yard to avoid future damages & take steps as needed.- These lights were perfect for areas that are near & face my neighbors homes.- They have a wide range of light with the side angles- Have long lasting batteries which can withstand the local cat patrol who circle my garage & my neighbors garden every 5min ALL.night.long. I have other lights, which get much more sun exposure that last an hour/2 at most.- Provide enough light to identify what is out there without being so bright it annoys the neighbors all nite.Other lights I purchased were too bright or not bright enough.I only wish they were able to fit a small, side sensor on the angles as well. I did buy another set similar to this which has the side sensors, but it's much bigger & brighter. Those are used in the far back.Install is a breeze. You can use the screws. However, where not possible, I used a black, super adhesive, duck tape, especially on vinyl siding.I used this tape on a previous set of lights I installed 5+yrs ago. It took a few days to remember I had used tape, not screws, & a lot of work to remove them. (So some 3M, double sided tape would also be a beneficial addition)These are pretty strong/well built - surviving a few accidental drops onto multiple surfaces from about 3ft. Including concrete, asphalt, & wood floors. As well as pingponging off a couple items before coming to a stop.**I do not recommend testing this. I have done that for you with my clumsy hands. Just take my word for it, k?? I got lucky...those times.They also seem to hold a charge for a couple days at least. I have not fully tested this out yet. However, I had left 1 in my garage for a couple days & the light had no negative effect on it in that time.I'm still testing out all the lights purchased for distance sensitivity & best positioning, so cannot speak to that yet. Tho I wish ALL motion lights had a way to adjust that as needed, as well as a timer. The sudden light can cause the animal to freeze, which, while working in conjunction with my sec cams, can cause recording to stop. Then it becomes a guessing game if its species is not obvious.I don't recommend these for long distance placement. I feel they do best closer to the house/garage/ other structures & utilize the higher lumens/led#'s the further from the house I go (my yard is approx 80-120(ft/yrds?) long.Bottom line - I found these very useful for close to the house/camera usage. But not for long range usage. Unless you are looking to startle &/or be able to follow the general path of an animal/person for daytime investigation. Or you have a good pair of long range, night vision binoculars. ?I will update this in a few weeks once I've been able to test some of it's abilities & compare to the 4-5 other types I purchased at the same time.One of the lights do not hold program. This is my second order of them. Fist order great second disappointmentThe installation is two screws under the Sun. To that and you can forget about them. Maybe a night check to make sure you have turn them on the way you want. It is very bright and so far so good.The Biling Solar light is not as bright as I had hoped. I does provide enough light to see where you are going, but I was hoping more for a 100w light bulb effect rather than a 40w. I suppose because of the design it is more of a flood light rather than a spotlight.It is easy to install. I didn't really want to drill holes in the side of my garage, so I used velcro to install on the wall and the unit is light weight enough, it should stay put. The motion detection seems okay, haven't really tested sensitivity at a distance, but it turns on as I pull up to park in the driveway. I do wish it stayed on longer as it seems to turn off way to quickly. I saw where another reviewer said it stayed on for 30 seconds and that sounds about right. I would have rather it stayed on for a couple of minutes. I've only had the light for a week or so, but there have been no problems in regard to charging.In summary: Not as bright as I would like. Doesn't stay on as long as I'd like. Easy to install. Charging is fine. I would recommend this light if you just need to see where you're going or just sitting around BS'ing with others and want a nice cozy light. I would not recommend if you're wanting to use it to do something like work on your car or see how your BBQ is progressing.Need a lot sunThere bright and work pretty good minus one stopped working the first week and now i cant get a refundIt works good it's very important that you read the instructions. And make sure it's completely charged. If this doesn't work put it in a dark closet so that the battery can run out and then charge it up again. It worked for meStraight out of the box, one of the light refute to turn on. I have spare 18650 battery laying around so I opened it just to find out. Their battery might be decent as it weights 42 gram. However, they sealed connectors to existing battery so the only way to change is to resolder - no thanks. I like the fact that they have front push button, not too many vendor does this. Mode 1/3 is good when when it senses you but you have to be 8ft away and at least 70 degree off - in other word not sensitive at all. So called enhanced PIR is terrible. Also, it doesn't run for 30s like some viewer claimed, I counted 15s. I have yet to see a vendor that makes this setting adjustable. Mode 2 is not on full blast, more like medium blast which is okay but I'd prefer full blast. I don't understand why did all the vendor choose to stop this feature. With a decent 18650 battery you should have no problem running full blast all night. Last comment on full blast mode, no way this thing is putting out 2500lm - just no way more like 1000lm I have other lights that were putting twice the brightest at 2500lm
