You didn’t go to GE and check out their spectrum info. Nearly a 100% match. Light coming thru curtains is more of a spectrum change than swapping bulb types.
I have to physically feel the bulb in my home office to know which type I have installed.
And the great part is turn on delay is near zero, but is slightly noticeable in the 100W bulbs.
I got a bunch of 60W equiv. offbrand free after rebate from Lowe’s. They use 13W. Gave one to my parents at least two years ago, it’s still burning above the stove and that “night light” has 50%+ duty cycle.
I was using a 60W incandescent light bulb in a hood above the stove as a night light that was on 24/7. The life of the bulb about 1 month. The small area where the bulb is located could cause heat build up from the bulb it's self and shorten the bulb life. (My guess)
I was buying replacement bulbs at Walmart and purchased 2 fluorescent screw in bulbs. Cost $7.00 for two. The first bulb lasted 14 months leaving it on 24/7. Replaced it with the second bulb about 2 months ago.
When the second fluorescent burns out I will try a 15 to 25 watt incandescent to see how long they last, perhaps one of them will last longer than the 60 watt.
Do I like the light from the fluorescent? NO. Have I considered screw in fluorescents for other locations in the house? Yes, but I have not found other uses for them.
I don’t care what their website says, I care what my eyes say. And my eyes say that every time I turn on the lights in the ceiling fan that’s half CFLs it doesn’t seem like they’re all lit, there’s a dimness that always makes me look up and check. Maybe the new ones are better, that doesn’t seem to be the general consensus when the topic comes up, most people seem less satisfied with the newer ones.
