“That was the final straw, I *had* to buy it” was quite good! It gave me a good laugh.

I just picked up a couple of square Old Street lamp style heads off ebay with 30 LEDs with an optional switched internal PIR to illuminate 28 of them on motion sense with two on permanently.The solar panel is 210 mm x 210 mm and measuring in sunlight gives 6,22 volt @ 28 mA with a 3600 mAh 3.6 volt battery pack installed that works in a similar way if the panel produces any voltage it turns the light off. That said if my calculations are correct its going to take over 100 hours to charge the pack up and the light only stays on for 2-3 hours under normal charging conditions so I have bodged the circuitry board from an 18650 3.7v battery charger in a case to make a permanent feed instead of the battery pack. Testing shows energy produced from the solar panel turns off the light so it looks good to go, testing commences.

Happy Christmas Clive!

I have a similar street light. But one day the sensing system stopped working. It won't go back to full brightness anymore, just dim light. After turning it on using the switch, it will light up full brightness for 20-30 secs perhaps then go back to dim. I can't find where to buy this whole circuit board.

I recently bought one of these types of lights off of Amazon for an industrial property that has had recent break-ins in the area. The one I bought was about $240, but it is 100,000 lumens bright when it detects motion, and then dims down to something like 10,000 once the motion timer has expired. It has very nice glass solar cells completely covering the top of the unit, has radar detection, has a 30Ah pack of 18650's inside, comes with a remote control to be able to setup the options from the ground, and came with a fairly decent mounting bracket and pole. The design of mine has quite a peaked top, with the solar cells covering both sides, and is quite nice because the snow we get here slides right off of it. If it had a flat-top, I fear I would be climbing up there to brush the snow off it when we get an inch or more. (which is quite often in the winter here). It has been working everyday for several months now, and gets enough charge during the gray winter months here to keep going. It wasn't exactly a cheap light, but it seems to be worth what I paid for it.

Top vid, Happy new year to you Clive.

I've seen a few live open street lights recently, makes me want to poke around because of you 😅

Surprisingly radarsensors are cheaper than PIR ones (20 cents for the RF transistor vs $2 for a pyroelectric sensor). But those also have a lot of downsides: they require certification, they consume more power than PIR ones (not suitable for wireless alarm systems), they can detect you through walls which can be a problem for indoor use.

That cell is 32700, mostly around 4.8Ah to 6Ah in capacity. Their chemistry are either li-ion (3.7V) while few are li-fe (3.2V), most of the times.

We've just had solar street lights put up in our work car park in an attempt to (a) be more ecologically responsible and/or (b) avoid the cost of digging half the car park up to repair the damaged power feed cable. The lamps are two piece with solar cells rotated to maximise sun exposure and the lamps have a more consistent angle. I'd love to say they are good, but let's say we have had some teething problems, not least that they were flat within 3 days and then would run for about 30 minutes an afternoon (if that). Apparently a software fix will sort them - at least if put into a movement activated mode like this one they might stand a chance. Clive:. Difficult to judge the size of that solar panel via my phone screen but I'm trying to compare it against the one I use for my homebrew weather station down at the bottom of my garden... Mine is one of the really common 165x165mm ones off eBay and is capable of over 500mA in full summer sun (6V) and it looks like you have about double that area on your cell, if the cell is only 3Ah that is going to be pretty good for a lot of the year, but agonisingly, not when you need it most. My solar weather station draws between 7 and 8mA and has about 3Ah in two 18650 Lithium Ion laptop cells. Even in winter it is kept fully charged all year round except for the dingiest of days (worst I have ever seen is 4 days without ant charging), guess it could be a bit tougher in your neck of the woods. You can see my power supply data here: thingspeak.com/channels/343059 and the weather data here: www.wunderground.com/personal-weather-station/dashboard?ID=ILONDON691 It is probably worth adding that I replaced a sensor in the summer, losing the mAh count (rebooting with battery already charged), so I need to wait for a bright day and dump the charge into a fat resistor to get it back to the correct baseline. Thanks for the video, I love the reverse engineering of power supplies and solar stuff.

"Radar" is really just the principle, and it can be implemented in many ways. It's what accuracy and resolution you expect from the implementation that makes it cheap or expensive. This here is really just a very simple resonating circuit that is deliberately laid out open and unscreened to -abuse- creatively employ natural weaknesses of such type of circuits, namely both radiating radio waves and being themselves affected by radio waves. Sure, you won't be able to pinpoint and track aircraft and missiles at thousands of kilometres with it, but if THOSE are the types of visitors you regularly require to detect, turning on a light at your door will probably not be very high on the list of things to automate when they do come visiting.

I had bought one of these with 3 led clusters in it and I had always wondered what was inside. I'm hoping that mine has more than one cell in it, but it does have a really big solar cell on top.

Ah, yes. The joys of solar power on a rainy or overcast day. The 30 watt monocrystalline panel that keeps the batteries for the shed lighting charged barely got the battery voltage above 13 volts today (float is 13.6, overnight dropback is usually about 12.8). The 250 watt polycrystalline panel that keeps the solar generator charged actually peaked at about 10 watts with today's lack of light :-( That panel was tested under load and can deliver 235 watts in full sun (the Jinko panel has very good output under real world conditions). I had one of the smaller Banggood solar streetlights that worked well until water penetrated the poorly sealed solar panel and it disintegrated. The battery, LEDs and the controller board are OK so I have a 4" X 4" solar panel on order and I'll try mounting and sealing it with some clear "waterproof" tape. I also have one of their "wall" solar motion lights mounted on the shed out back and it is partially protected from the rain by the overhang of the roof. However, most of the solar panel gets light for about half the day and this light is strictly motion-triggered - sometimes by a neighbor's cat at 12 feet and on occasion by a vehicle using the back driveway as a place to turn around - enough heat in motion works at greater distances ;-) I built the solar gen so I'm not out in the dark or a thunderstorm getting a gasoline generator running to supply limited power during the (usually short) commercial power outages (a concession to old age ;-) The 540AH 12 volt AGM battery bank powers a 2000 watt pure sine wave inverter that connects to a 4 circuit transfer switch with options of power for furnace, fridge, kitchen counters and some lights. Depending on the season, the solar gen can provide "Wait until daylight" power for 8 to 24 hours. Historically, most outages have been less than 24 hours so this level of backup power means I rarely need to get a gas gen connected and started.

I know the feeling.We have had about a week of overcast. The solar shed lights would be dead by 0100. The 200 watt capacity panels were doing good to get to 30 watts. But if the wind turbines had been up and running, they would have likely gone to brake mode.

I too am rather fascinated by street lights. A few years ago the A Road near me was mainly changed from low pressure sodium to LED. But some of the fittings were not changed. These turned out to be those that went off during about midnight to 6am. This left a rather messy overall look, although recently all the road is LED. On the subject of radar detectors, my porch light has one fitted internally, triggered from behind the opal glass cover. It still works remarkably well, going through the double glazed front door and picking up movement inside the house.

Silly cone adhesive tends to come apart better under heat, like headlights on cars.. stick in oven at 180 or lowest temp for 30 mins, the glass shouldnt break but whatever theyre using in the solar cells to make em solar could cause it to crack but doubtful because being solar they absorb heat so should be good.. just fyi, i know it is impossible to get the glass off of a headlight unless you heat it to right under the point where the plastic abs gets floppy...

Dude who are you and why are you doing this? I sense great awesomeness and some old school sarcasm... Thank you sir!

One good thing, the LEDs appear to be recessed which should minimise light pollution. You say the original opening is on the solar panel side. If there is even the slightest gap in the sealant, water can get in. If there are no holes on the bottom, or the holes are not on the very lowest point, it can fill up with water. It seems much more preferable for any opening that could leak to be on the underside. What sort of frequency does the radar work on?

The reflectors may no as useful as on standard bulbs but in my testing they still increase brightness approximately 5-10% for leds. All depending on the angle of the reflector though of course, the farther out it comes the more stray light it catches.

Hi, Clive you say in the comments that the cell only puts out 70mA in the current lighting condition and it doesn't bode well for all night illumination. It isn't designed for all night illumination, its designed for illumination when a moving body is sensed.

About that 32700 number, I thought it was a direct extension from 2032 cells being 20 mm Ø times 3.2mm tall, just needing an extra digit for 70.0mm tall button cells.

Always good to have a good solar light in places it helps reduce crimes

Looking at the moulding and the way the battery was attached to the housing it almost seems as if this was designed for a different battery pack.
