Using a Light Tent

[#1]

I recently bought a light tent and have just now tried using it for the first time. It's completely white, and pretty big, fold up, and I put a daylight bulb shining down from above (outside the tent). I am disappointed in the photos, however, They don't seem to be anywhere near as bright as the photos I took out in the sun. I thought they would be brighter and clearer, but not so. See the best photos from the tent here:

And photos I took in the sun can be seen on these items:

What am I doing wrong?

Ah, those aggravating pictures. I have tried everything. I even have a light box that is all enclosed with the 3 holes in it. Sill get shadows and if I try to use white it gets blue. Even went to a professional photographer to get help.
Needless to say I am still working on it. I have switched back to the gray background simply because it is easier to shoot than stark white.

I just put my items on white bristol board by a large window. I brighten them in photoshop:

I always wanted to buy a light tent, but dammit I'm cheap. LOL
