Colour temprature bulb

OldGoat

I'm putting together a few bits and pieces to do a small product shot. Reading around a couple of tutorials it seems that using CFL (compact fluorescent) in the 5000k range (daylight) is the prefered otpion. Now I have access to a couple of 6400k 35W lamps and I'm wondering if they would be suitable rather then hunting out and ordering a pair of the 5000k range.

just get all the same type of bulb and do a custom white balance

Do you know what CRI has that lamp? (CRI is Colour Rendering Index, the more the better, up to 100 - for natural sunlight)

Found on the internet:
"Fluorescents, both conventional and compact, generally have rather poor CRIs, often in the 60-75 range, even when they are rated as a "daylight" type or 5000K. The special "full spectrum" lamps that are available at higher prices generally have CRIs in the 89-92 range. "

they tried push those full spectrum lights for offices a while back, apparently better on the ol eyes

I don't have the bulb here in front of me but I'll check for CRI tomorrow.
The supplier was saying that each manufacturer labels their own version of what range 'Daylight' should be, from 4600k through 5000k and up to the 6400k I have. :rolleyes:
As suggested I'll use a pair of them and custom the white balance. On the plus side there might be a 8" square tube in the same colour temp range that would work really nicely in a home made light-table.

What kind of product are you shooting? Do you have access to a strobe? Colour temperature is that that big as deal if you are shooting in raw.

Have a look at this vid and others from the same guy for ideas: http://www.youtube.com/watch?v=OxDG3WDT7Kw
