A few years ago i decided to do up my whole house in those new LED X-mas lights.
I saw a tree done up all in blue LED’s in NH and thought it looked really nice.
Well, what a big mistake that was.
The whole house lit up in this sickly blue and green colors.
looked nasty.
Plus the LED’s would blink at what i imagine 60 times a second.
Completely nauseating.
Now i have a 50 pound bag of useless LED X-mas lights.

That has me wondering if these new LED indoor lights are any better.
Do they blink real fast like my X-mas lights did.
will i get a headache whenever i turn my head too fast?
Have they figured out how to make the LED’s a softer, more comfortable omni-directional light?

That is what is known as PWM or pulse width modulation. The light is turning on and off many times per second. There are LEDs that are run with constant current that do not pulsate. It is the driver of the LED that will determine this.

There are also neutral white LEDs that produce a near incandescent light which is more pleasing to the eye and colors appear more natural than with colder white LED lights. Hopefully when costs come down LED interior lighting will become a norm.
