Just a word of warning about "hanging" envirolites. On emmpey's advice, I decided to take my light, which was previously hanging vertically (see above photos), and put it back into a hood, to hang horizontally.

Anyway, I discovered that the plastic base of the light was ROASTING hot (couldn't hold it in my hand) and I'm glad I caught it when I did! It appears that, due to the way the light hangs, all of the heat rises upwards (yes, I know, envirolites aren't meant to be hot - but they are, take my word for it!).

This heat passes directly over the plastic base and it appears that this could be quite a fire hazard. To test it, I decided to touch the other light base (red spectrum) which is hanging horizontally in a hood. Yup, it was as cool as a cucumber.

So...I would strongly advise you NOT to hang envirolite bulbs vertically. ANY bulbs for that matter. Even if you've got ventilation etc, it won't matter because the heat rises upwards over the plastic base, thus heating it up.

Sincere thanks emmpey - you may well have, inadvertently, prevented a fire there! Much appreciated.
