The projector has taken in water and no longer turns on, even though it promised in its description that it is completely waterproof.

600w is definitely not, I can say it's around 20w to 30w compared to a regular projector, but I didn't expect much more for solar. The battery seems quite good, lasts all night and maybe even 2 nights

The review is about the Jortan white solar led 600W:

The box contains both batteries for the remote. The remote works from a distance, unlike other models that require you to be right next to it. I tested it even from a distance of 10 meters at an angle and from 15 meters across from the lamp. It goes without saying that the remote must see the front side of the LED lamp (the receiver/sensor is located right next to the red lights).

The information and instructions in the box and in the small manual are not good. They are more confusing and it would be better if they weren't there at all.

The box states that the AUTO button on the remote is SMART DIMMING MODE, which when pressed does not seem to do anything, while the manual states that it is AUTOMATIC MODE, with no explanation.

The box states that the red button on the remote is SPACE BAR, while the manual states that it is EXPOSURE TO DUCK. No logical explanation. That's why I write below for the help of other buyers:

Pressing the ON button, the LED lamp lights up at 100% brightness, and pressing OFF turns it off. The button with the full sun gives you 100% brightness, while the button with the half sun gives you 50% brightness. With the + and - buttons on the remote, you can adjust its brightness, which is divided into 10 stages (by 10%).

The 5 red lights that indicate how charged the battery is (20% each) remain lit during the day. The only way for them to turn off is during the night (in general darkness) and as the LED lamp turns on, you press OFF and both the LED lamp and the 5 red lights turn off. Once the LED lamp "catches" light (e.g., sunlight), then those red lights turn on to show you how much charge it has, but even then I imagine it tries to catch charge from the solar panel.

The cable between the LED lamp and the solar panel is 3.50 meters long.

Fully charged, the LED lamp automatically turned on 5 minutes after sunset at full brightness and turned off again automatically when the sun rose, that is, after 12 hours. And there was still some charge left in the battery, so it has very good duration.

It seems that this automatic system is built-in and cannot be canceled (or I did not find a way to cancel it), which may be negative for some. On the other hand, of course, I imagine that this is how all solar panels were designed, to turn on and off automatically. Of course, when the LED lamp turns on by itself, you can turn it off by pressing OFF on the remote and it will remain off until the next night, etc. The only solution I found online is to install an extra switch, to turn it on and off whenever you want, and not automatically by itself, if you do not want it to turn on and off automatically.

I did not find out what exactly the AUTO button does, as it seems to be built-in, as I described above.

I do not find that the red and blue lights that resemble police or alarm have any particular use, which turn on with the red button on the remote and turn off with the central button M.

Fortunately, it does not have a motion sensor because I did not want it to have one for the purpose for which I bought it.

As for the buttons 3H, 5H, and 8H: While the LED lamp is on, pressing the 3H button, the lamp turns off and turns back on once, so it received the command to turn off by itself in 3 hours. And it indeed works. Logically, the 5H works for 5 hours and the 8H for 8 hours respectively.

The box also contains screws to secure both the collector and the LED lamp to the wall/ceiling. Personally, I used different screws. The U shape for the collector is relatively small in thickness, and the screws of the U shape on the collector are not the best. Much better is the one for the LED lamp. In general, I would suggest a very good fastening for them so they don't come off due to winds and rainwater.

I bought the lamp to light up a space of 300 sq.m. (15x20) and I am satisfied. I installed it 3 meters off the ground. I played a bit with the control, but now I think I will rarely use it since the LED lamp will blink on its own. I recommend it with my eyes closed at the price of 49 euros that I bought it for.

From information on the internet that the manufacturer does not mention, I found that it needs 6-8 hours of charging in the sun and the maximum battery life is 18 hours (on full charge). Recommended position is 3-4 meters off the ground. Recommended cleaning of the solar panel from dust, etc., every 3 months for maximum performance. Lighting area: up to 300 sq.m. Light diffusion: 120 degrees. Lifespan of the LED lamp: 50,000 hours. Warranty: 1 year.

If any issue arises, I will follow up.
