it's funny you said that. hahahahaha.. last night i went out to the corner store at 2:00 am to pick up a mini fire extinguisher. i allmost didnt sleep in fear of waking up in flames. the two flourescent lights REALLY heated up the inside of the box, (i find using one of them is sufficient in terms of heat) but the whole inside is tin foil and the heat really didnt escape. the top of the box was a bit warm. but it's all good this morning. im glad.
