GeoBulb Arrives
I received today from C. Crane my first GeoBulb. It's a GeoBulb II in cool white. Standard Edison socket, 60 watt equivalent light, draws 7.5 watts, 30,000 hour life, $50 plus shipping. The bulb is quite heavy, relative to the incandescent bulb it replaced. It's cool to the touch when illuminated. Nice white light. It buzzes softly, but I only hear it if I put my ear within a few inches. Won't be able to fully judge it until the sun goes down, and when I discover if it really does last for three years, but so far I'm happy with it.

It looks pretty white to me. I took a photo of a silver dollar on top of a white piece of paper. It's here (66K). The paper looks gray. But that was during the day, so some of the illumination was sunlight from outside. When I think of it, I'll take another one at night.

Hard to say for sure. It's got a little color-cast according to the histogram, but I can't tell what sort of white-balance adjustment your camera might have done. Looks like it might be usable, though.

Ahh, here's the data sheet: http://www.geobulb.com/documents/GeoBulb-Cool-White-lab-report-13170.pdf
Looks like it's got a bit of a goofy curve. Probably okay for reading, but not for anything color-sensitive, so I couldn't use it near the computer / printer.

So is it white? Or some weird off-white that feels unnatural?
