Jeff,
I also have bought some "sunlight" and I think I have seen Chroma 50

on

some (sunlight and chroma 50 the same?). The sleeves have a number on

it

that relates to color temperature. Don't have the sleeve handy but do

you

remember what it was?

some expensive specialty bulbs I got at a lighting store.<

What would these be. The ones above are around 6/7 bucks at HD and
other stores. Daylights are the standard 99 cent bulbs that are

commonly

used in a house.

Jon,

Now that I'm at home, I've had a look at the "expensive" bulbs I
mentioned. They're 40WT12 EXCELLA bulbs. They have a CRI of 91.1.
There's some propaganda on the web at
http://www.atlantalightbulbs.com/excella.html

"Daylight" and "Sunlight" are marketing names. See the page that
Dave Nelson sent out
http://www.cinematography.com/docs/flo_tubes.asp
for info on which bulbs have a high CRI.

Regards,

-Jeff
