My Tortoise is not eating or walking

Our little Tunisan Spur Thigh Tortoise Alix seems very unhappy. Normally he's very active, doing several trips to his food corner on a daily basis. However since the beginning of December he's been off it. I have to lift him out of his bedroom in the morning and he just stays underneath his basking lamp all day, he does not even turn around. I have to bring his food to him but he hardly touches it if at all. I have e-mailed where I bought him from and they have recommend leaving his lamp on for 12 hours a day and with the temp of between 30 to 35. Could it be his lamp??

I give him a bath every morning, and he does wee in his water which leaves a powder residue (which could be what I sprinkle on his food however I do not see him eating any).

His eyes are clear and his nose is dry.

Is it just the time of year???? is there anything I can do to make him his usual active self??
