LED Christams lights

This time of year is fun especialy with the houses all decorated with lights and if you are lucky enough to have snow that makes it even better. My question is why do the new Blue colored LED light mess with peoples vision, more so then the other color LED lights? Any thoughts?

Wavelength.

Try looking at them with high-minus lenses with low -ABBE materials!!

There is a peculiar quality on the blue LED lights, I like it.

This year I got lucky and found a bunch of solar lights, so half my inside tree and all of my outside lights are done in solar, with LED back-ups on the tree inside. Good thing the solar lights come with a long cord.

LED's tend to have narrow waveband transmission, while incandescent lamps rely on the color of the glass they are encased with.

Love them though. 400 LED lights outside barely pull one amp (I've got a Kill-A-Watt EZ - nice tool) where 400 normal lights would pull eight times that much. Can really save on electricity.

They flicker at a much faster rate

**Geirskogul** · 12-13-2010, 07:27 PM

No, they flicker at 60hz (or 50 hz if that's what your supply is) just like incandescents. Unlike standard bulbs, though, the "filament" isn't glowing inbetween AC waves so you may experience a slight flicker at long distances or unreliable power sources. Some people can see it others can't.

The flicker drives me crazy but no-one else in our house seems to see it.

Lovely.........but, they are a little short in the lumens department, and make for a duullll Christmas.

Depends on which lights you buy. Some LED lights can output the same amount of lumens, or if you want you can string two lights along the same run. They're much thinner wires and it's definitely doable. Then you're only pulling 25% the electricity to match lumens instead of 12% for half the lumens (though it's really more like 12% the elec for 70-80% of the lumens of incans). Besides the flicker, which is eliminated in high-end strings, there is NO downside to LED lights that I can see.
