The,

4509 110,111 cp 100 watts used incandescent

Q4509 140,000 cp 100 watts used halogen

So has anybody anything to offer by way of comparison?


Go with the halogen by all means! In our Tobago, the light is much
brighter than what we had with incandescent (same bulb types you
quote). The beam is a little more narrowly focussed, though. Major
benefit is the vastly improved life-time of the halogen bulbs.
