My hubby is going blind and it's so hard to find a bulb bright enough to help him with his failing vision issues, but these sure did the trick. The lighting in our house has never been good so I ordered ours in 60 watt (Daylight), and the second I flipped on the light my hubby said, "Oh yeah, now that's what I'm talking about. Let there be light." lol
The bulbs are actually so bright that he has since had me unscrew 2 of them out of the ceiling fan light because he said they were making it hard for him to see the TV Screen that he uses as his computer monitor because the bright light was reflecting in it. 40 watt bulbs might have been more than enough for our needs, but we weren't taking any chances, and now we'll just have 2 more of these awesome bulbs to use later.
