LEDs are diodes (which emit light when forward biased), and as such, they are polarity sensitive. A LED powered by AC will light on only one half-cycle. For this reason, many fixtures made for use on AC will have a full-wave rectifier before them (this allows the use of almost twice as much power). It is these where adding a diode (polarity doesn't matter) will reduce the brightness.
BTW, most LED Christmas lights have two series of 25-35* LEDs each. Some have one series on each polarity and others use a full-wave rectifier. You can tell which by trying it with a diode. You'll get either only one series lit or both at lower brightness.
- - I don't know, but I suppose strings for 240V countries have twice as many LEDs per series.

Okay. Like I said I have zero experience with Christmas lights since the
1950's style with the small incandescent bulbs that had to be replaced regularly.- Vote on answer

Had you temporarily pegged on the wrong side of the argument for some reason.

I can often see better on warm white CFLs vs hotter. On LEDs I like 5000K for shop. Daylight not sure if they have same bandwidth as real Daylight.

IIRC, they don't. There's blue (LED) and yellow present. If it's done right, it should look white (although I have seen some that look purple, as well as the typical yellow).

Daylight LEDs look the same as real daylight to me, certainly 10 times closer than that artificial warm crap, which is more like candlelight. Come on guys this is the 21st century, we can make real light!

Most of them speak English, and I think only a third can speak Welsh. T= he signs are all dual language. The first two signs you see when enteri= ng Wales are "Croeso i Gymru" shortly followed by "Camer=E2u cyflymder".= Or "Welcome to Wales" and "Speed cameras"

I don't see the problem with Ireland, we should either just take it and kill all the Catholics, or let them have the tiny little piece of land and forget about them.

I suppose it's better than road signs in Salish like we have on the rez.

You've been trying to kill the Catholics since Oliver Cromwell's day with little success. Just kiss Ulster goodbye and be done with it before the PIRA wakes up.

Same here, 12C. Predictions are impossible. They said 10C the other day and it was 0C. Another excuse for the council not to use grit.
