Hello,

I was thinking of fitting an emergency light near the CU. It's under
the stairs, so there's no daylight to see by when an RCD or MCB trips.
I see they use an 8w bulb. How bright are these? I know a 7w cfl is
supposed to be equivalent to a 40w filament bulb. Are these lights as
bright as a 40w bulb? I'm wondering whether it could be used as the
only light in the room or whether I need a "normal" light in addition
to the emergency one?

Thanks,
Stephen.

As discussed here a while back, be aware that these things take 4-8W
even when not illuminated! It would be cheaper to just fit a battery-
operated standby light somewhere. IIRC seeing some LED ones in the
local pound shop for ... well, you work it out.
