Nothing wrong with the figures. For a large commercial building it may
make sense to change all their halogens at once - the calculations
don't even take into account the cost of more frequent re-lamping with
halogens.

If the replacement units produce less light and poorer quality light,
then the 'savings' aren't very meaningful. The numbers themselves look
ok, on a cursory look. I'd expect any premises that uses 43kW of

Quite true. Though in many locations (particularly those perpetually
lit - such as walkways/halls/passages/stairs) the light quality may be
secondary to running costs and/or maintenance costs.

Or an org that has a larger number of smaller buildings that it is
responsible for.
