LED string 9000 hour test result.

The amount of metal in the wire is usually quite low. I'm not sure any of the stuff could be recycled, which is a shame.

Yes. They gradually lose intensity and colour shift over time. But imperceivably slowly.

Big Clive

I tried getting oil into a set and it didn't really work.

Clive, would that dimming pertain to led bulbs for regular house use. You know for lamps and such?

Yay! ...the UT210 is brought into the game, 2 minutes before full time. [Breaks out a celebratory glass of Advocaat].

My thoughts, too. What's the ageing mechanism and is there a lever to wiggle? Coz it could be age, temperature, UV, drive (ie Coulombs). I'm sure the traffic sign people have some good data though.

I was just wondering, when you spoke about renewing the lights every so often, apart from obviously the copper or Aluminium in the wire, how much of the actual led is recyclable and is the stuff hazardous? I know gallium is non toxic, but are it's compounds? perhaps you know or one of your viewers knows the answer.- just me and my ever curious mind working overtime in this age of renewable energy and using up resources as opposed to recycling. (We had glass milk bottles when I was a kid and paper carrier bags with string handles) ;)

BC explained that at the start of the video. There is a reason. Watch it again

It would be interesting to see what happens, when you injekt oil, wachs ore other preservative things with a seringe under the heatshrink sleaving before using them outside. And if it helps to slow down the corrasion and degretion of the LED's

Is there a way to figure out if it was the phosphor or the LED that failed faster? Some of the ones on the test string looked like they'd failed completely. Would they have lasted longer if not pushed to full brightness? Maybe that is the next test.

That was a good run time out of those Clive. Do you think it has helped the lights survive with them turned on the whole time? They haven't really had a chance to pump that water in as in an on off environment, as in hot cold hot cold cycle. Love your work mate, great vids. Cheers

I was a bit nervous when you fiddled with the lights and the exposed alligator clips.

He talked about corrosion, so MY guess would be outside. Let's hope so, anyway......

Chuck Kirchner

Did not know that , ThankYou, Have been watching dim-lights. er Dimwits all day, We call them Democrats.

Did you have the degraded lights indoors or outside?

Should probably buy some higher quality shrouded clips

I did that with a loose clip on my bench last week, unfortunately it slipped under a PCB I was working on and destroyed a chip!
