I was skeptical that these lights would be both a true warm white, and as bright as claims and pictures from other reviewers. But these lights surprised me; they are much larger than expected and thus, are a tad bit of an eyesore (as they're plastic and the light face and solar panels are very large for a spotlight.). But they are indeed bright and last much longer than any other all-solar light I have tried, and they seem to shine much farther as well. I can point them upwards in the direction of a 25-35 foot tree and light it from root to tips.

PROS
1) well made, strong stakes
2) huge solar panel takes in a lot of energy and light bulb panel is wide and big
3) very bright light
4) warmer white light, not blue or bright white
5) do not flicker at all & stay lit for at least 6-7 hours, even with minimal sunlight (rainy mornings and a few hours of sun and they still come on and stay lit like clockwork.

CONS:
1) they are not a true 2500 ultra warm or even incandescent or 3200 neutral warm. I would consider these closer to a 3500 nuetral or even cool warm white. They have sort of a greenish hue instead of the orange-ish hue that one expects from a true warm white. They're not soft white though, and may show as a true 3000 warm on a red brick or natural stone house - anything other than siding, or any type of rock hardscsping or shrubbery you are trying to light up may actually be really ideal for these lights. But my home is an ivory/cream colored siding and these lights reflect a yellow green hue that isn't the most attractive to me.
2) the range of motion while on the stakes is not as forgiving as most spotlights. There is a great range up and down and there are tension knobs on both the light lens and the solar panel, but you cannot twist the light right or left to angle it. But if you pull out the stake and readjust it solves that problem. If you are mounting this with screws to something, you might have difficulty getting it positioned the way you want.

For the price these lights are great for not needing any wires or electricity, and they stay plenty bright from dusk until about 1-2am... so I can't complain. Highly recommend these for those wanting to spotlight directly on brick or stone homes, or anyone wanting to light up dark yard or pool areas, trees, shrubs, plant or rock gardens, ponds, etc.

Note, I purchased these lights from another seller whose listing stated that the lights were warm white. They were Innotek brand, which I am familiar with in other products. The Innotek brand lights did not give off the green hue that these do, so now I am going to order more of the other brand as the light is definitely warm white and not this yellow-green color. Oddly, I ordered 8 of this lights (two boxes of 2 each) and they're not all the same color. Some (6) are this yellow green color, and 2 of them are an actual warm white. I feel as if there has been some kind of manufacturing change or something and some boxes have this yellow green colored light. You can actually see the yellow green hue on the light face before even turning it on. This is a bit aggravating for folks like me who purchased several sets to light up the front of their home and yard/landscaping.

I already threw out the boxes so I ended up putting the 6 green yellow lights on the side and back of my house and ordered 4 more of the Innotek brand so i would be sure the front of my house was lit in warm white.

I will say that they Innotek brand is not as bright and does not stay lit as long as this brand. They stay lit for well over 7-8 hours each night and they are much brighter than other brands. They're not LED flashlight bright, but who wants that on their home and front yard anyway. If you're looking for a flood light type spotlight, this isn't it.

I ordered a couple boxes of these to uplight the stone walls in my front yard. They all worked on arrival and hold a good charge. The light they give off a bit too yellow or what I ultimately wanted so only get these if you want a warm light.

Very bright with two settings. So far these have lasted all night. I would buy again.

These seem to hold up well.

These were the second purchase of these lights. Total of 10 so far. Others several years old. One has died - not sure the cause: both the solar panel and the internal battery still functions. Probably corroded contacts on the circuit board. Otherwise I think they are pretty good even though I have lost one.
