    Probably yes to both questions, but this depends on your setup. What are the reasons for your concern?

    Default Never Touch Any Lightbulb!!!!!!!!!!!!!!!!!!!!!!!!!!!

    PROBABLY YES? He must be kidding. A 400 mh will heat up a ten by ten room almost 10 degrees without being cooled. As for cool to the touch the ARC (yes an arc) inside the bulb BURNS at like 1500 degrees so I hope that helps a little.
    I grow em' all, and know em' all. Later ya'll
