Landing lights, incandescent, halogen and Xenon HID
I have finally got my wing tips painted and on my Seneca, they have the
hid lights in them. I had the Piper wingtip recognition lights before, 35 watters, not good enough to show a light in daylight. My attention is now turning towards my actual landing lights. These are located on the nosegear strut. I am thinking of getting halogens to replace the incandescents. Has anybody done this and did you see much of a difference, if so, how much? I don't want to get hid's for the nose gear, there is only one manufacturer that has an stc for this. I don't like the installation set up. Specifically the ballast being glued up inside the wheelwell. Also in cold weather it will take awhile to warm them up, I will probably have landed by then. For those who don't know, the lights go out when the gear goes up (a good thing really) even if the switches are still on. 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?

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. -- Thomas Borchert (EDDH) |

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.

Landing lights, incandescent, halogen and Xenon HID
From Avtek======== http://www.avtek2.com/halogen_lights.htm
Test environment was a dark country road, power supply holding a consent 13.8 volts and a grove of trees 1/3 mile away. Judges were six NON-Pilots with no bias at all as to the test results. 1) 4509 barely hit the trees and no details could be observed, due to the "Yellowish light" 2) Halogen hit the trees, and details such as green leaves and branches were seen. However the pattern was tight. 3) H-I-D hit the trees unlike Halogen, the H-I-D light-up the all the Trees and nests could be seen. The light was Pure White 4) Q-4509 Hit all the Trees as with H-I-D but the light went further and beyond to houses 3/4 mile away, in a wider pattern, and a deer was seen in the field, not seen by the other lights. Wow, interesting. However, with two quarts bulbs going, I get the feeling I may have them dim down in the flare as the throttles are closed. I am again leaning toward the hid option for the nosewheel. At the cost not being too significant I may put in the Q's just for an experiment.
