Anyone know of such a thing please.
I am at a loss as I have minimal knowledge of this subject.
I am looking for discharge luminaires with a rough equivalence to 1000w
tungsten/halogen. These will be controlled by either time switches or
dusk/dawn sensors.
Must give a white, not amber/yellow, light.
I've googled for hours and find myself more confused than ever. No doubt I
am not putting the right search in but I don't really know what I'm looking
for.
Tungsten/halogen I vaguely understand as that is what I use now. Several
luminaires are well past the use-by date. So I would like to replace them
with more modern and efficient units.
Son, Sox, HQI, metal halide ! The choices seem bewildering but, as yet, I
am unable to find a simple explanation or comparison of different types.

Any help would be much appreciated.

Thanks

Philip.
