Re: [APD] Coralife CF questions and when do CF's die

Bulbs burn brighter when they are hotter, up to a point.
The maker designs the bulb for an anticipated operating
environment. Hotter bulbs also have shorter lives.

Is running a bulb in the fuxture gong to make it hot enough
to be significantly brighter or to fail substantially
sooner than otherwise?

I imagine the diff will be slight. Running one bulb with
the fan on means that bulb will probably run a bit cooler
than otherwise and to therefore be a little bit dimmer and
last a little longer, which will probably offset the diffs
with the other bulb.

I imagine the fan the Coralife fixtures has only a small
effect on cooling (it's a very small fan) and is there more
for the situation where two bulbs are burning than one.
