I just spoke with Dan at AeroVisions. The information on their landing lights
can be found at http://www.aerovisions.com/HID/hid_products.html. It gives
all the info needed. But instead of trying to calculate current draw (V x A =
W), the 28V kits draw about 1.5 to 2 amps. The 14V kits draw 3 to 3.5 amps.
The lower range tends to be the load when the alternator is up to full speed
and the higher level is what they tend to draw at the battery voltage.
I inquired about the heat produced in an enclosed space. He said that it's
about half of what an incandescent would create in the same space. He quoted
their test measurements to be around 150'F on the lamp housing after an hour
running.
He also mentioned that the rectangular reflectors provide good illumination
as a landing light, but for the best performance, a round reflector will
always provide the best results. And the larger the reflector the better
again.
