Rainy - "I tried LED a few times but they are so bright they give me headaches."
Not what you were asking, but old standard incandescence bulbs are almost gone.
How to find comfortable LED bulbs:
I always keep bulb packages for the numerical power and output values, and this helps in comparing LED to the old incandescent bulbs. Yes, I kept some old incandescence bulb packages assuming the change-over might be confusing.
They've labeled these LED's in a somewhat misleading way. Its not all about
watts, unless your only concerned about
power usage, which the manufacture is trying to please the low power initiative. You want visual comfort, which is not their main concern.
So what you want to look at is comparing "Lumens" output and "K" value (which is related to warm light (color of fire) vs cool light(middle) to daylight sun. One is brightness and one is intensity. These were also listed on some of the better name brand old incandescent bulbs.
Example- new LED's "comparable to old 60watt" can be anywhere from 580 to 800 lumens. This is a HUGE difference to the eye. Its on the package in small print.
Then K value of 2500 (warm) is less intense vs 3500 (cool/middle) to 5000 (daylight very intense) which is hard on the eyes in a dark area. K value is shown on a scale line usually along with with "warm" and "cool" to daylight".
The old "soft white" is what "warm" is now (low K). Avoid "daylight" (high K value) indoors unless its a workshop environment or a commercial kitchen.
The world has thrown away so many of these new bulbs out of complete confusion that it probable washed out the environment benefits of the change so far. All because of poor packaging/info for the consumer.
Those florescent "ice cream cone swirl" bulbs from a few years ago were a total joke, and mostly obsolete by now. There were not meant to go in landfills either (but are), should be recycled to get the heavy metals out.
Oh..........I wrote a book assuming you were confused by this as well. Some other readers might be. I was at first.
