Other than the absence of a suitable mount (easily fixed), does anyone see
any problem with this light as a landing light?

I'm considering upgrading from a 50W Halogen lamp, and understand that I
should get ~2x the lumens from a 30W HID. This light has a 12 degree beam
angle and the housing is 2 3/4" in diameter. Their floodlight (in the same
housing) has a 36 degree beam angle.

Thoughts?
