This really is impressive because only the low pressure sodium vapour
lamp and the microwave pumped sulphur lamp are in that league.

I recently was in a shopping mall lit by (I think) metal halide lamps
(big white bulb, probably E40 cap).

Some of those fittings had been retrofitted with large spiral CFLs and I
was impressed with their brightness and colour rendition. They were so
bright it was difficult to look at them directly.

This seems to me to be a suitable case for using CFL rather than LED as
a replacement.

True enough at the moment but it looks very much as though that's
about to change sometime in the next two to three years.
