5000w solar LED street light

An interesting light, but also a prime example of how eBay sellers are very prone to out of control exaggeration to sell their wares.
The circuitry in this mass produced item has been "optimised" to the hilt, with the charging of the lithium cell controlled by the microcontroller, no voltage regulation and no resistor in series with the LEDs which results in quite a squirmy current when tested on a bench supply.
The LED current at various cell voltages was:-
4V = 2A
3.4V = 1A
3V = 600mA
2.5V = 11mA
The lithium cell capacity yielded a slightly lacklustre 1200mAh on the first cycle. I may run some more cycles on it.
There are a few hacks that can be done to this light. First one is to add a 1 ohm (2W) resistor (or higher) to cap the LED current to a sensible level. That will also give longer run time on a charge.
The easiest hack is to swap the lithium cell for a higher capacity one, but note that the solar panel is probably only rated about 100mA on a good day. So the larger cell will only have an advantage in PIR only mode and with just occasional triggering.
From a waterproofing perspective, the PCB would benefit from a coating of lacquer or grease to shield it from condensation, the battery contacts would also benefit from some grease and the on/off slide switch is best bypassed.
The shape and angle of the case means that it should be fairly resilient to rain.
The solar panel is laid into a recess in the plastic case and covered in resin. Extremes of temperature may cause delamination or cracking of the silicon strips. It will probably discolour and cloud quite quickly, but that can be improved by polishing it with a fine abrasive cream like T-cut or toothpaste.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- www.bigclive.com/coffee.htm
This also keeps the channel independent of KZbin's algorithm quirks, allowing it to be a bit more dangerous and naughty.

[@chrishartley1210]

The 5000W is assuming 240V input. for the same current at a nominal 3.7V you get 77W. And of course that's the equivalent power if it was a tungsten filament lamp so the actual wattage is about 1/8 of that, ie 10W. That's Chinese maths explained.

I have four lights in my yard which use a charge and control circuit similar to this one. They’re in metal enclosures and branded “Better Homes and Gardens.” Inside, there are two 18650 “Westinghouse 2000 maH” cells paralleled. The output is a Luxeon LED, supposedly 120 Lumens. The solar panel is about the same size as the panel shown in Clive’s video. The oldest lamp has been operating for more than three years on the original cells. That is over 1,000 charge cycles. There is a slight dusk detection difference in the MCU. On my lights, there is about 30 seconds of hysteresis programmed apparently to prevent the moving evening shadows or passing car lights at night from making the light cycle off/on.

I run my washing machine and air fryer etc only when there is enough sun during the day so you do have to plan a bit but not much.

Ac unit and no compressor.. exists, sort of... Search adsorption refrigeration.. ammonia and water, hydrogen. The cycle starts with a small gas generated flame, and when temperature is achieved , flame is reduced to a minimum to just maintain that temperature. The old mechanical systems were best with fixed high and low flame points but have evolved with electronics to extinguish and relight the flame..which requires more parts and battery backup. Great refrigerator/freezer in the wilderness where local power utility is not readily available.

I have one of these but the version without a remote, it’s above my garage door which is in a dark corner and has been working merrily away for a couple of years now.

[@wombatillo]

The FET marked as A2SHB has an RDS(ON) of 75 milliOhms at 2.5V gate voltage and 50 mOhm at 4.5V. They're probably using the combined resistance and voltage drops of the FET, the J3Y transistor collector-emitter and the internal lithium cell series resistance as a form of regulation. Cost savings is the name of the game.

[@albear972]

[@dawidciso9614]

I used a similar LED sensor lamp to build a high-power flashlight. The COB module that has all the led's can handle absurd level of current as soon as you bolt it to a radiator. Main drawback is that the array usually has all led's wired in parallel, making it susceptible to thermal runaway. I was able to get away with 15W (5A) of power from a panel that is even smaller than the one in the video. Needed an additional DC/DC converter to step-down battery voltage and regulate led current but those are not that expensive on ebay either.

[@flipoclock]

I currently have one of these in use at the start of driveway in damp, wet West Cork, Ireland and other than the screws rusting a bit on the outside, it is holding up very well after nearly a year... Good value for money!

[@markfergerson2145]

I’m slightly surprised the SOS mode does nothing. If this device were used as a front porch light, you could activate it to let others know you’re having an emergency. It’s one of the few places the damned ubiquitous SOS mode in LED devices actually makes sense. The five thousand watt “rating” probably refers to how many watts it can expend before it dies of some random fault.

[@steverabson4049]

I bought two, based partially on your review and partially out of my own curiosity. £6.15 a pop. Eventually fitted to the wall and set to low level all night, with high level proximity detection. Obviously not 5000W but we all know that is a bit of a joke description (I hope they aren't serious there). I noticed online that some listing's are 6 kW. Anyway, tbh, these things are surprisingly good and they last all night as far as I can tell. I've now bought 4 more to fit around the garden, same price as before. I haven't bridged the switches yet like you always recommend, but the construction suggests that moisture may not be an issue for a while. If the damp gets in then the soldering iron comes out. Great video by the way. Thanks

[@Roobotics]

For the PIR, it's not a singular spots for a single person walking across the frame, it's more like a bedazzled disco ball, the many lenses are there to make it chaotic but focused on the sensor region, since it uses differential settling and amplification, the goal is to make it so IR dots swing between the two sensor regions rapidly enough to register a diff signal, from what I've gathered.

Great for ambiance garden light with remote control, but the only issue is the flickering on mode 3, still flickering even after adding additional resistor to the led.

Random flickering can be cause by a failing LED. Continuous strobing flicker at a fixed frequency is often just visible pulse width modulation.

[@LordCarpenter]

I would be curious to find out if the solar cell can fully recharge the battery after, say, eight hours of continuous nighttime use. Many of the solar lamps I've seen fall short of that, resulting in the battery being so depleted after several days of use that the light turns off after only a few hours each night.

[@DelticEngine]

The small LED modules look like the type used in head torches. It would be an interesting modification to swap some parts. For example, the head torch COB modules often include a red LED. It would be interesting to have a 'street light' that could output a red night vision light as well a white light, or switch from one colour to the other when triggered or depending on the ambient light level. I suppose I'm getting ahead of myself, but I can't help thinking it would be interesting to come up with a user-programmable chip, or even a module, that would be a drop-in replacement for the existing chip but provide custom functionality.

@Bigclivedotcom some Pic micro's have a brown-out detection circuit that can be programmed to trigger at certain voltages. So it might be using that. But also, some Pic micros have ADC channels that are connected to the power rail input so the pic can measure their own supply voltage without using another pin. As for controlling the charge, the MCU proberbly has the pin set to analogue input thereby making it Z-state (floating) untill it needs to shut off the charging. The clamping diodes in the chip will prevent it going too high above the supply voltage.

clive i see in your notes how to tidy up the surface of the solar panel after it has deteriorated with sun exposure. i might add that one of your viewers once mentioned that wetting the panel with methylated spirits restores the surface too.

[@laserspike]

ROFLMAO. I love that those skinny little wires to the LEDs can cope with over 1 kA 🙂

[@2Sorts]

Would’ve been interesting to know the max output from the solar & the current those COBs draw when at full brightness. This would’ve given a typical charge & run time.

[@bigclivedotcom]

There's more data in the description.

[@chrisengland5523]

At 5000 watts, it presumably produces several gigalumens.

[@sie4431]

We've had several of these cheap outdoor lights with built it solar and the light output had been appalling while that battery has been some cheap aa rechargable. This thing looks like it might actually be fit for purpose. I'd be interested in knowing it's lumens and whether the solar panel and battery can do their job adequately

[@occamraiser]

You have to admire these amazing Chinese engineers packing 5 KW into such a small light. Also, I was shocked to see how far photo-voltaic technology has advanced with a few quare inches of collector powering this awesome device. Seriously, we need to find a way to punish these liars. Personally I advocate buying them and then returning them as defective when they can't output 5KW, eBay will fully refund including return postage if the seller wants it returned and then withhold the cost from the seller. Hence we are not out of pocket and the lying seller has paid for postage with no sale. Obviously this is a MUST if ever you get something that isn't perfect and is stupidly over-sold. I sent a PTZ camera back that I didn't like, as faulty, 'because the zoom didn't work'. Obviously it didn't have zoom - none of the things Chinese eBayers call PTZ really have a Z, but it meant I didn't have to pay for the return and the seller who had lied about the spec - even talking about zoom in the description - lost out....as he so richly deserves. Also, if I ever receive a product with one of those absurdly dangerous undersized 3 pin (out of spec / illegal) plugs I simply return it as defective and suggest that the seller stop selling them as I have contacted their local trading standards office....which on two occasions I actually did do.

[@micheals1992]

It produces the same amount of light as a 5000w heating element 😜

"Thankfully the SOS button does not..." - commandos come crashing in through the windows, kicking in the door, helicopters circling above...

[@gregorythomas333]

5,000 watts...pretty much like the 9,000,000mAH 4 cell battery banks they keep trying to see me :)

[@demef758]

The SOS feature is only available on the super deluxe option of the street light that sells for $7.99€.

[@houlej19]

When you record a light and your camera’s exposure doesn’t change, that light is pretty much as powerful as your smartphone screen

[@bigclivedotcom]

Exposure is locked during videos.

[@jacobbellwood6184]

I have the model without the remote and remote sensor and found I could change to the higher capacity battery if I wanted. I might when the battery fails.

[@ronostrenski8359]

Great tear down as usual. I was wondering, did you measure the current through the leds?

[@bigclivedotcom]

That data at various emulated cell voltages is in the description.

[@ronostrenski8359]

@@bigclivedotcomThanks

[@stevenA44]

I'm surprised that was only 7.99. Looks like a pretty decent light. Kinda makes me want to order one.

[@HenryLoenwind]

If you have the use case for it, do it. I have 5 of them and am mostly happy with them. There are just a couple of mechanical issues to be aware of: (1) They can be angled up, but the production quality of that mechanism varies wildly, so plan with them angled horizontally---that's where most of them end up after a day of rain. (2) The piece that connects them to the mounting plate is a bit brittle, and the mounting plate holds it tightly, so it will break if you mechanically abuse it. (3) The PIR cone is not very wide, so when mounted horizontally (see no.1) just above head height (that's how high my fence posts are), you'll have to step up to about 1.5m for it to activate.

[@christopherleubner6633]

Each cob subassembly will be 5 to 7W electrical. This light does not seem to run it anywhere near its full power. It is likely driving it with a PWM signal. The solar panel is sized so the Voc is equal to the max safe charge of the battery, about 4V in most of these. The LEDs themselves have a forward voltage high enough that it prevents over discharge as well, typically 3.3V.

[@davefish4965]

I have 4 of these on the path behind my house,the oldest one is at least 2 years old now and still performing brilliantly,I really cannot fault them other than the pigeons try to land on them sio they drop down 've had to fabricate some spikes to stop them

[@lockdot2]

Great video! What kind of rechargeable battery is good for something like this? I need a rechargeable AAA battery as well. I don't like the price, but in the long run I heard they are cheaper. And the cheap ones I got wore out very fast. Which ones do you recommend?

[@bigclivedotcom]

Rechargeables do work out much cheaper in the long run, but don't always work in some products due to their slightly lower voltage. The choice of cell technology will depend on the application.

[@SakariNy]

Honestly this light doesnt look bad if you want streetlight style garden lights. Could modify this for external dc supply or external battery

[@christopherleubner6633]

Or modify with the ability to have a built in USB 5V charger so it can be used to charge a device.

[@bigclivedotcom]

It could be powered from a USB style power supply.

[@twistedsaltypretzel7727]

This control module is pretty neat. Do you have current measurements (from supply / to COB) for standby and output modes? Timing is hard coded into MCU or is there a mechanism to adjust timeout / hysteresis? Cheers for another sweet video! 5KW LED WOO!

[@bigclivedotcom]

There's more data about LED current in the description.

[@PetraKann]

I am not sure what’s going on but every time I watch one of the “big clive” videos, i get a strong craving for at least one shot of single malt whisky - one moment please 🥃

Imagine being a competent engineering team in China who passes their perfectly adequate design to the marketing team who slaps a big number on the front and calls it a day.
