Also these guys.

Hard to tell by the pics. If they look like they're slowly dying, then maybe.

Tricks for damping off--

Air circulation -- maybe set up a small fan
Bottom water --- set packs in a tub of water that has about an inch or so of water for about 15 minutes when watering
Don't over water -- let top of soil dry out before watering(more people kill seedlings from over watering than under watering
3% hydrogen peroxide -- spray the soil surface
Chamomile tea -- drink a cup, and then use the used tea bag to make another cup -- spray on soil
cinnamon -- sprinkle a little on soil...this helps keep the fungus gnats away.

Don't get discouraged. I had quite a bout with damping off and peppers. Keep asking questions. It's the cheapest way to learn.

By the way -- you learned already. Keep the shoplights about that distance from the top of the plants. Just right above them without touching.

Can't really tell without decent light. My damping off problem I had in the the past with seedlings is that they will absolutely keel over and the stem at the soil level looks shriveled and rotten, kinda damp looking. If they are slowly dying or turning yellow or any other slow process, it's probably NOT damping off. Mine were sudden and fatal.

edweather: I guess "slowly" can be subjective. A couple days is slow to me. edweather's right though -- at the very base of the stem, you would see them shriveling to a flimsy stalk -- almost like something was choking it.
