gewoodfo New Member United States 13 Posts	Posted 01/17/2008 09:38 am Hi all: I am in the process of setting up a table top studio for taking coin photos. I am trying to determine what type of constant lights to use. I want them to be small because I do not have a lot of table space and I plan to store them in a briefcase along with light tent, camera, etc when I am not using them! i have been told that I need bulbs with: a color temp of 5000 - 5600; a CRI index of 91+ and as close to 100 as I can get it. low heat output Do you agree with those requirements? Is there any other specs that I should be looking for? And last: Any specific bulb recommendations? Thanks Report this Post to the Staff

The low heat is the tough part. These bulbs are awesome, but they burn very hot and last only about 4 hours. Shop CCF Members on eBay. Report this Post to the Staff

I usually have to adjust white balance on the camera, and sometimes again in Photoshop Elements to get the color right on my coin shots. It would be nice to minimize the amount of time I need to spend post-processing! Coppers seem easier to "get right" than silver. Silver, especially unc's and proofs, really gives me trouble. Best wishes. Report this Post to the Staff
just carl Bedrock of the Community United States 20753 Posts	Posted 01/20/2008 09:56 am Sounds like your really short of space. Have you tried just using a space near a window? Of course that limits you to daytime photos. Placing eveything in one small case including the camera doesn't sound easy. A few light stands, camera, lamps, possible extension cords all in one briefcase? The word briefcase alone indicates a small item. Note the first part, brief. Good luck Report this Post to the Staff
tights24 Pillar of the Community United States 2254 Posts	Posted 01/20/2008 10:57 am I'm stealing one of Superdave's pics of his old set-up. In this pic, you can see the two small lights he is using, and his pictures with them speak for themselves. I believe he called them MR16's. Report this Post to the Staff
gewoodfo New Member United States 13 Posts	Posted 01/30/2008 10:58 am Hi all: Well, I may have found an LED lamp and fixture manufacturer that meets my specs of 5000 -5600 color temp and a CRI of 92. I am waiting on them to get back to me with a cost to make them. Will keep you posted! Who would be interested in trying these out? Thanks, Report this Post to the Staff

Beyond that, placement is pretty much everything. All the same, I'm interested in seeing the results of such an exacting light specification. Report this Post to the Staff
