The bulb/holder assembly must dissipate its heat somewhere. So, if the unit is in my wingtip, that's where the heat eventually goes. The holder assy may be fine for the temperatures it generates but I'm afraid that the underlying structure, eglass/carbon epoxy, can't take it as a heat sink. 2. Narrow is a relative term :) I agree that a pencil thin beam is too thin. This is why I've been using the GE 4509 as a reference point: I personally like its beam spread. 3. Critters abound in North Western New Jersey, mostly deer and in herds of 20! I REALLY appreciate your comment here! 4. I also agree that a relatively diffuse focus is best for taxi and recognition purposes, turning corners ect. The better "driving lights" seem great for this purpose.
