Has anyone used GE Reveal light bulbs for indoor photography?

Screw You.


Sorry, I'm taken.


Regarding your item (2):
I did "read the thread" ... and you left it incomplete.


That's called snipping. Reading the thread means YOU read the original posters
message.

You provided information without any form of analysis ... I provided the
missing information and the analysis of the light bulb's (non)suitability
for the task at hand.


If you had read the OP's post you would realize that he was totally conversant
with the problem of using incandescent lighting.

Cheers,
Alan.

Just happened across this post and thought I would give my .02.

Incandescent Full Spectrum lighting really leaves a lot to be
desired... You simply cannot achieve high-qualiity sunlight emulation
with neodymium coating. Sure they look nice and bright and cheery, but
to accurately (scientifically) reproduce sunlight, you need to use
fluorescent light bulbs. Fluorescents DO NOT use neodymium coating but
actual phosphors to represent color temperature.

The best I have seen are the Westinghouse Realite Full Spectrum light
bulbs. You can see them online at:
http://www.servicelighting.com/catal...m?prod=AL04836

They are 2,200 lumens, 6,500K (perfect Daylight) and 94 CRI.
Sylvania's daylight bulb has 90 CRI and Philips has 84.

Thanks.

Had you googled the thread you would have seen the conclusion, that at 2850K the
GE Reveals are far from sunlight, or rather, hardly different than other tungstens.

Where is the spec for color temp and output? That spec says 600 lumens, by the
way. As they are Halogen I doubt they are much different than another tungsten
lights in color temp.

They are 2,200 lumens, 6,500K (perfect Daylight) and 94 CRI.

Surely you're talking about a different lamp than the one at the link above.

Oops... my bad - I posted the wrong link. That was a halogen bulb.


Try this one for the 4' Westinghouse Full Spectrum I was referring to:

CRI is high (good). It would be nice if they would spec the temp in K.
