Hello -

In response to local burglaries, some relatives have been advised by the
police to install a dusk-to-dawn low-level floodlight in their small (15
metres across) farmyard., which already has motion-activated halogen lamps.

The police recommend a sodium lamp, but are the CFL-based floodlights also
suitable?
Sodium lamps with dusk-til-dawn sensors seem to be quite thin on the ground,
should I use a separate sensor?
Can anyone comment on whether these might be suitable?

Thanks.

The various types of sodium light all have way better energy
efficiency, and thus lower run costs, than CFL

If you dont mind spending extra dough for white light, cfl or linear
fl are an option.
