I purchased the Siedlinlar Solar Dock Lights last week. When I got the lights I was impressed with their construction. They were not like the cheap knock-offs that you see in big box stores--these are solid with a low low profile and bright blue lights that looks exactly like what you see in the short video clip on their advertisement. Although I have had them for only a week I am very pleased with this product. Of note, be aware of is that it does not mention on the box or the instructions that the batteries are already installed in the lights when you get them. I did not want to unnecessarily open mine so I emailed Siedinlar's customer service to find out. I got an answer back right away (yes they are installed) and what type of battery I would need should I have to replace it (1.2v Ni-MH AAA rechargeable). I have found that after a full day charge the lights last all night. In short I would buy this product again and am glad I found them. I think you will too---Ray Shedlick

I've been through a number of varieties of solar powered rechargeable LED lights. This is the first set that actually works. The installation is super easy. The level of light emitted is really perfect. I have these blue ones placed in a few strategic places on our dock to prevent missteps at night after going out for stargazing. The blue light is actually a little bright for this purpose but I'm sure I could put some tape over the LED lenses if I wanted to. I'm hoping for red ones to come out next season which I'll swap into those positions next year. I have two important things that apply to the product regardless of color and to the manufacturer/seller. First, when I first ordered the white variety, one of the lights did not work. I contacted the seller since I already had three of them installed and didn't want to uninstall the other three. Without a question, they sent me a replacement (which worked perfectly). Second, opening the defective unit was easy and I replaced the rechargeable battery which is a standard AA NiMH battery with an AmazonBasics model. Since replacing, the unit has charged and lit reliably (around 5 weeks now I believe). All in all, I am extremely happy with these units in terms of their performance, maintainability, and the support delivered by the manufacturer.

We have 300' pier with a boathouse at the end. For the last 8 years we have used 28 led pathway lights to mark the edges of the pier, the boathouse, and steps down to the upper and lower crab decks. Having marker lights really helps guests, especially when the moon isn't bright. The website for our old ones says "these solar path lights are built to withstand the elements for a long service life". Hogwash, they would get water in them during the first rain. Even so, the lights would last through the summer, and we considered the safety of our guests important enough that we replaced the old ones about once a year. At $35 for a pack of four it was expensive. So I bought 7 packs of these lights to see how well they would do. The price was about the same, they claim to be IP68 waterproof, and I didn't have anything to loose. I installed them 6 weeks ago. They have held up well very well. During the past 6 weeks our rain gauge has measured over 19" of rain. So far not a single one of the lights shows any sign of internal moisture. We are VERY happy with them. They are bright, look like they will last much longer than the old lights, and I can even replace the batteries. These lights could save us a lot of money. After about 4 weeks, one of the lights got noticeably dimmer and would only light up for a few minutes and then go out. Last week I sent a message to Seidinlar's customer service just before I went to bed. There was a reply in my inbox the next morning. They asked for my address so they could send a replacement, no other questions asked. My replacement arrived in 4 days. Now that's Customer service! We are very happy with these lights and two of our neighbors are ordering lights for their piers.

Easy to install as long as you have the right tools to preset the wholes in the concrete for the plastic inserts. Once you place the inserts all you have to do is screw the lights down. If you are applying the lights to wood all you will need is just regular wood drill bits and the plastic inserts will not be necessary. A full day of sun with no clouds will energize the lights for the entire night! LED lights are Awesome!!

I purchased eight (two four packs) of these for my dock. Worked great. Nice bright light throughout the entire night no matter how cloudy the day. Then the windstorm came. It blew so hard it flipped the entire 70 foot dock upside down! I do not screw the lights on to the dock. So they ended up on the lake bottom. It took about a week before we were able to reinstall the dock and find some of the lights. We initially found five of them, and after removing them from the drink and sitting them in the sun, they all lit up and continue to do so three months later. I then found light number six about three weeks later. After a month in water it worked and continues to do so! But wait! There's more! I just found light number seven. It's been in the water for three months, and yes, it is now back on the dock and working fine! I don't know if I'll ever find the last light. We're going back South for the winter now, but if I do find it, it will have been frozen in ice. If it works I will certainly report it. Needless to say I'm a big fan of these lights.

I bought 7 packs of 4 of these lights to put on our dock about a year ago. 25 are currently installed, 2 failed and I still have one as a spare. We are in a coastal environment and we're having strong winds and our dock has been overwashed most of today--I just checked and all 25 lights are on. Two out of 28 may seem like a high failure rate but these things cost less than $10 each. Full disclosure, I did remove the aluminum case and sealed the seam between the plastic parts with silicon--this probably voids the warranty but it does seem to improve the waterproof capability and the silicon should be relatively easy to remove when the batteries need replacing--I'm hoping the will last two or three years. The lights are bright enough that when installed every 10 feet they will keep you from stepping off the edge of the dock. Although they are not bright enough to read by, I wouldn't want them any brighter. All in all I'm pleased with the lights so far.

After buying the flat ones and having them only last a year I decided to see if I could find a higher quality version for my driveway, walkway and patio. Well these are exactly what I was looking for. The difference was noticeable the second I took them out of the box. Installation was super easy, although I was mounting them on anything I could put a screw in, the heavy duty double sided gorilla tape for outside use worked perfectly and literally took seconds to install. They are so great that I've had a number of neighbors call and ask where I got them. So far they've been perfect. They are uniformed brightness across all of them. I don't give many things 5 stars, as I feel everything could have some form of improvement, but I really don't know how these could be any better.

The media could not be loaded. The lights have been working for about two weeks. Their light is good enough in my little back yard. So far I am very impressed and I am thinking to order another set for my front yard. But please make sure that you turn them on and let them charge in the sun for awhile before expecting a night long glow. I guess this would lower my electric bill sinificantly.

Arrived very quick. Upon arrival I set them into direct sunlight for 3 hours then put them in the garage, turned them on and watched as 3 of the four stayed on all night. The fourth one was fine but needed more charging time. As I only needed 3, I installed those that stayed on all night. They give off a beautiful soft blue light and stay on from dusk until dawn. I mounted then on 1 foot high decorative pavers to keep cars from making u turns inside our yard (we're the first house in a developement along a long entrance). I was always having to fill in the ruts caused by vehicles turning around on the edge of our lawn. Although the pavers have been there awhile and worked fine, I just felt it was necessary to give the vehicles more warning. Neighbors are already asking me where I got them and our HOA is happy! Good solid construction (not plastic like some others I looked at) so let's see how long they last. I like that you can replace the battery. 2 thumbs up for these lights so far! Highly recommended.

these lights are great. used them for the driveway. Instead of drilling holes in the concrete I used Gorilla Glue Heavy Duty Construction adhesive to permanently secure to the driveway. I let the adhesive cure over night and now these things wont budge. Drive the car over them and let it rain all day and it does not matter. Will buy more again soon! Oh yea, make sure to let these charge in the sun for a full day and then take to a dark room where they turn on before you install. You must hit the ON button and make sure they are on before you secure. Otherwise if you forget, they will be stuck to the concrete.
