What is Mankind's Greatest Invention?

LED lights also run cool so you can use them for growing dope without having to use an expensive venting system.

Well now that we're onto appliances enough can't be said for obviously electricity itself and freezers .

Just read about how fucked up this shit is:

These lamps are terrible. I would pull every single one of them out of the ground and make the companies that profited off this graft pay every cent it costs to put the old lamps back in the ground.

So these people had a streetlight shining into their window, but that was ok. Now that it’s LED, they’re victims of environmentalism.

:thumbs up:

Stop acting like a faggot. You understand the problem. LED lamps are far brighter, bluer, and will fucking temporally blind you. LED lights in your home, or shining through your window, can seriously fuck with your sleep. Outside they fuck with vegetation too.

As street lamps they are bloody awful.

LED lights changed my life.
When I first went off grid about 30 years ago bulbs used 21w so I had to use candles a lot to save my batteries.
Then 12v fluorescent tubes came in and did the job for about 10w. Nice and bright but the tubes are damaged if you use them on a low voltage (when the battery was going flat).
My current LEDs use less than 2w.
For a tenner, I was able to buy a set of 4 remote controlled LED lights which can change colour and flash like a disco if you want them to.
I fucking love LEDs.

LEDs come in all sorts of light tones (colours).
You can get them in a warmer red to yellow tone for inside your house and a bright blue white for security lighting outside.

I bought one of these last year, for next to nothing, to light my back steps. Works brilliantly.

The problem with security is that bright blue is NOT what you want at all. You are better off with incandescent bulbs (very low light) that are down low near the ground and covered so that they do not shine directly into your eyes.

Where LED lights work for security is a an LED flashlight or, at best, strategic floodlights that light up perpetrators actually closing on the structure the lights help secure, but turn off otherwise so you can see your perimeter and beyond.

Bright lights of any kind are very terrible for security. One of the problems with properly securing a flight line in a combat zone, for instance, is that a flight line requires very bright lights surrounding the tarmac, but the people on the tarmac cannot see beyond those lights.

I had a super low wattage LED bulb in my last van. It was like 1.1 or something. Not bright enough to read but it was comfy.

Don't know if all of these are "inventions", but anyway:
Making fire. Pretty much what separates humans from animals. Of course there's some smart birds who use fire, but they haven't figured out how to make it yet.
Agriculture. This is what made human civilization, and opened up for specialization of skills for different people. Also, it made cities possible.
Writing. Made it possible to exchange ideas, and write down history, and made trade between cities possible. Wouldn't be necessary without first inventing agriculture though.

Great civilizations have existed without steel, boats, and even the scientific method. But all of them had fire, agriculture and writing. It's what separates the advanced meso-american civilizations from the hunter-gatherers further north. It's also why the Old Norse culture pretty much died out, when confronted with the extreme focus on writing from the christian cultures. We had a written language, but we didn't have a culture that valued it as much as the anglos. We didn't have professionals that just focused on writing down history, until christianity came. (Or maybe we did, but the christians burned it all down, but I think that's unlikely).

Agriculture wouldn't have made much difference without pottery. Storage of excess food was made possible through large ceramic pots.
