HOLY CRAPOLA SUPERNOVA THIS THING IS BRIGHT Good lord, I had no idea so much light could come out of a single light socket. You will be utterly amazed by this thing. It’s like having daylight in the middle of the room; I seriously sometimes forget that it’s nighttime.
Very nice Apparently, this bulb is intended for photographers. However, if you are looking for a replacement for sunlight in your home, this is it.

I leave it off early in the morning when it is dark outside when I first wake up. “My eyes, my eyes!” However, it is perfect to light everything up the rest of the day and evening. Exactly what I wanted. (If I get a second one I can duplicate the effect of having the Sun in this room without all the heat.) Be sure to get a 14″ lamp harp which I could only find at [...]
