Thanks Thomas. That is the sort of stuff I was looking for. I read the
halogens are 7x7 degrees and the incandescents were 12x7 or 8 degrees. I
can live with that. And I think that is with the filliament horizontal,
but it did not say. Most people mount the filament vertical and I guess
that would be better for a landing light. I can have two on my nosewheel
strut. I guess I will have some fooling around to do, aiming them.

I just really wanted someone to tell me yea or nay.

Again thanks.

John

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.
