Wow... well, you've definitely got your work cut out for you in figuring this one out! I'm sure with everyone's input, you'll do just fine once you get the hang of it. I think you told me when we were pm'ing that this is a new model that the company has just released? If that's the case, they may not have worked all the kinks out of the system yet. It would help them, as well as you, to contact them and let them know what's going on. Other people might be experiencing this same situation, and if there's any type of problem with the new unit's construction (like, say, too much light for the space or lights that are too hot for the space), then the company should be made aware of it. I'm just assuming it came with the lights... not sure if you bought the lights yourself... if you bought your own lights, there's a possibility you may have gone too bright/hot... is there a way you can put some more distance between the lights and the growing area? Can you stick a little prop in between the lights and the grow area to back the lights up by a few inches? Even a few inches will make a big difference. Obviously that's not what you want to be doing permanently, but for now it may help until you can get some insight from the company....

On the "bright" side... your Dendrobium seedlings are adorable! They look very healthy and should do quite well for you. They're not fussy, so they should do fine in the orchidarium, even with the rising temps. And it appears you've mounted your leptotes bicolor on your wood doggy's rear end? I love it! He's got a fuzzy bum!! Too cute!!!
