Fun fact! Harsh, cold lights often have the opposite effect than one desires from visibility. Since the light doesn’t diffuse as much, you end up with high contrast areas that essentially make it harder to see things outside the halo of very bright lights. I used to work in crime prevention and safety and the realization people have when you show them the impact of a “warm” light that spreads beyond its bright cone and one of these cheap “super bright” lights is always amazing. It’s a forehead-smacking moment for many.

I want to contribute that if you are arguing for traditional high pressure sodium, their CRI is so low that some things don't even seem to be illuminated under them. Cool white but focused streetlights are just another evil. Technology Connections makes a good video about this I personally feel that the color temperature, assuming the light is capable of a respectable CRI, isn't as important as the spread and diffusion of the light.

The drivers are often isolated on these. Albeit not to our standards.

We've got the grandfather of this light out the back. It's survived 12 + years of Australian summers, torrential rain and "slightly cooler" weather, with (so far) zero problems. They had skimped on the heatsink compound when we originally bought it, and it has the original square LED panel, so ours might be a "better quality" than the AliExpress seconds perhaps? Still seems to produce more than enough light.

To be fair, they probably don't have much of a need for heat sinks in places like Europe.

I've found that items from China are typically well made from a construction standpoint, with servicable hacks to improve the workings not that difficult to achieve. Take the case on this unit. Nicely done with surprising detail to reinforcment on stress areas and general heat sinkability.

I'm on my second of these now. On the first light the LEDs failed, but the current one is going on its third or fourth year. I live by the sea in a very windy region, so I'm quite impressed! When the first lamp went out, there were some minor rust around the screws holding the LED, but nothing on the cover. Might have been alu on the older version?

Nice to see that the manufacturer has employed a _British-style_ Earth in this instance!

I don't think they're fussed about the steel because I seriously doubt that the components are replaced when they fail. They probably just throw a new complete unit on and chuck the old ones in the recycling bin.

For what you pay this seems good value - that casting would cost a lot more if manufactured in the UK. As for rust all those screws looked like low grade (magnetic) stainless steel - so even if the covers rusted you would probably not be able to get them off anyway 😂😂😂😂

I suspect they've not gone for a driver on board, because it's rated for 85V to 250V, and the drive on board LEDs generally use a linear power supply, which is only rated for 230V. This means they can sell the same model in both 120V and 230V markets.

I purchased my first 10W LED floodlight in 2012 and it was 100% thick cast alloy, even the frame holding the glass, all screws and washers were stainless steel, only the C shaped support was mild steel. I paid over 30€ with shipping but it lasted about 26400 and something hours, I know that because it was wired in parallel with an hour meter. Anyway the COB LED failed because the driver decided to go from 300mA to over 1A, I had bought three of them and only used one, but since it lasted so long the other two must be now at the bottom of some box hidden under 40cm of other surplus things... It seems on all current units of the same style the glass frame is thin sheet steel and on most of them also the rear cover, while the screws are now galvanized steel.

I recently started playing Cyberpunk 2077 and there are LED streetlights in the game that look EXACTLY like this lamp, and the one you showed years ago.

My eyes bugged out when you got the continuity tone on the earth wire.

beside taking apart street light may be you can do a video showing how good the light coming out from the lamp.... that would be great.

@@LasseGreiner No, that's physics and physiology. The hotter a body is, the more blue and eventually ultraviolet. Our body and eyes assign red to "warm", as the heat that we feel is infrared, i.e. more to the red. So, basically: "Warm" is the amount of infrared that is sent. A hotter body also sends more infrared than a cool one. But the colour balance will move to blue / ultraviolet with higher temperature, because the blue part will raise much faster with temperature. So, "warm white" looks warmer to the eye, but it is produced by a colder body than "cold white" which contains more blue in addition

One big advantage of not using a DOB (Driver On Board) LED module is that it enables the use of 'smart' control gear by simply swapping out the basic driver rather than having to replace the whole LED chip as well. I suppose that, in theory at least, an RGB LED module and controller being fitted enabling the possibility of lighting effects or HCL (Human-Centric Lighting) functionality if someone wanted to do something really clever.

You should remind yourself that they probably have millions [if not billions] of unsold LED drivers [and LEDs that need drivers] that need to be used up before they can fully embrace the driverless LEDs ... similar thing happened with the 0.3mp cameras ... they had millions [if not billions] of 0.3mp cameras that they had to get rid of ... so they used software interpolation to help shift them. Another thing possibly worth remembering might be the fact that the factories that produced these LED lamps probably no longer exist !

If it comes with a short length of flying lead... you just know what the quality is going to be like.

The label suggests a driving voltage of 85 to 265 volts. Does the driver maintain a 30-watt power, and thus brigntness, regardless of voltage? Or does the power and brightness drop with lower driving voltage? Thanks for the great video.

The drivers maintain constant output.

So I'm guessing that the extra heatsink bit near the actual glass (with the six plastic thingies) is for extra cooling in that area since it has circuitry that can accumulate heat quickly.
