Inside a Chinese street light from eBay

[@parmesanzero7678]

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.

[@tubaman66]

5:02 lovely how all that is stopping the reflector from shorting the LED and/or making the whole fitting live is a couple of gobs of silicone on the LED connection points. Nice!

[@bigclivedotcom]

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

[@phils4634]

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.

[@two_tier_gary_rumain]

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

[@jeffwoehrle]

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. With better guts this would be a several hundred dollar unit here in the states, knocking on a grand if it came from someone like Hubbell or similar. Thanks for the video!

[@spvillano]

Nicely constructed, with a wibbly-wobbly ground and non-heat sinked driver. Oh well, the steel shan't have the opportunity to significantly rust and one does get what one pays for. Want a light that'll last a decade? It'll be around 10 - 20 times the price. I'd address the loose ground and use it around my home's exterior. Use the same LED and a 5 and a quarter meter light pipe/diffusor, I'd even use it to light my room.

Im an electrical distributor with my dad now and seeing the contrast between the cheapest things possible and actual brands that deal with this stuff is crazy. We stock parking lot heads that are 100-400w metal halide equivalents and they are WAY higher quality than stuff like this, full metal construction, wide angle glass lenses, much bigger led chip layout, color selectable, wattage selectable, the internal connections are also much nicer with wago connectors and solid ground terminals. Another difference between this direct from china street lamp and a dedicated fixture is for sure the cost though, even the lower powered ones we have are still ~150usd but this is way cheaper. I guess if you dont care all that much about quality and just need something then i guess it works

[@Santi81-theOne]

Im so glad that you explain Here this light, now i can sleep better. Thanks

[@DelticEngine]

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.

[@barrieshepherd7694]

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 😂😂😂😂

Exactly.

[@spvillano]

I doubt it's designed to last long enough to rust significantly.

[@MyProjectBoxChannel]

I literally just yesterday, spoke to the bloke fixing the LED street light outside my house😂. He replaced the driver module. It's all really well made. It was a surprisingly big module, very industrial, and reminiscent of a electronic ballast for a sodium lamp.

[@bigclivedotcom]

It's good that he changed the driver instead of swapping the whole light. I wonder if he set the LED current correctly.

[@MyProjectBoxChannel]

@@bigclivedotcom I'm not sure what functionality the driver had, it had many terminals, I should probably of taken a picture 🤔.

[@ruben_balea]

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.

[@Graham_Rule]

When you said "it is quite a cold 6500 Kelvin" I just realised that cold white is a lot hotter than warm white. Don't know why I'd never noticed that before.

[@LasseGreiner]

This comparison to black radiators and colour temperature always bothered me 😢 The principle makes no sense and the vocabulary even less. Probably an US standard.

[@Rainer_Landes]

@@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

[@GERMANIA292]

Way better than those "5000 watt" Solar street light, this one actually feels like it can be used outdoor

Another thing possibly worth remembering might be the fact that the factories that produced these LED lamps probably no longer exist !

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 don't know the point of the Earth if its on a metal pole stuck into the ground. Also if it is properly power-coated I would think it wouldn't rust as long as the coating wasn't damaged.

I've kept all my failed 230V LED lamps and converted some to 12V for my solar powered electrical system.

[@bigclivedotcom]

If an ungrounded metal lamp post becomes live there is no guarantee that enough current will flow to trip a breaker or blow a fuse.

[@hugolandheer7008]

Are they available in pink?

[@Comrade_YG]

Just buy spray paint

You can fit a burple growlight LED which makes the light output pink.

I wonder just how well that glass lens spreads out the light. Was there any testing done on that glass to get proper light spread. My guess is no.

To test the beam pattern I would need to find an area with long throw onto a flat surface.

30 watts at 20 foot in the air is terribly underpowered for a street light. Your lit area would be tiny and very shadowy. Real street lights use 10 times that power. Most 1k watt bulbs have been replaced by 300 watt LED

[@bigclivedotcom]

The power will depends on the height and application. You can get high profile street lights from 10W upwards.

Any tips regarding replacement battery packs for ebikes? I just paid a fortune for one based on the claim that it is made from 18650 Panasonic cells from a company that is at least based in the US. Those from Amaz## looked outright frightening, but go for about half the price. However, once I receive the pack, I cannot break the seal to open it and check without voiding my warranty. So I got to believe what is in there is what I paid for. And that still is not a guarantee that the battery management system (BMS) electronics is any good. A faulty BMS can blow the best quality cells, no matter what. Tricky situation it is.

eBike batteries are a minefield.

Can these type of led be used in disco lights to replace halogen bulbs?

[@bigclivedotcom]

Not easily as the optics are designed for a sharp point of light.

[@craigcousins6718]

@@bigclivedotcom do they make LEDs that easily replace bulbs as Ive seen lights such as datamoon and scanner that have been converted or are they pants?

[@asdfhun]

That metal plate covers at least 15-20% of the LED :O

For 43mm spigot.
