Bill Shank sent me his Whelen PLED1L landing lights
to get some performance data on them. The current draw
on these puppies looks like this:


[img]cid:7.1.0.9.0.20110902233330.01dcc538(at)aeroelectric.com.0[/img]

They don't even start to draw current until 8.8 volts and
go into constant 1.2 amps constant current above 12.5 volts.

The flashers we used to use for wig-wagging the incandescent lamps
won't work with these devices. I'm developing a new recommendation.
At 1.2 amps per lamp, the current draw is quite nominal. This
product ought to open some new horizons for Rotax powered aircraft
that have not been able to support the legacy landing light
products.

2.4 amps for DUAL landing lights and 1.2 amps in wig-wag is
quite doable with the Rotax 18A alternator.

Watch this space . . .
