Lighting specs
 

Can anyone point me to a document that will tell me the brightness (lumens) of a strobe approach light (ODALS omni directional approach light system) and a hihg intensity runway light?

Hi S,

Will this do? According to Google:
Approach Lights | Flight Light Inc.

Some of the incandescent bulbs seem to be 100, 150 or 200 watts.

Thanks GR, that's a good start - illustrates just how ignorant I am about what questions I need to ask!

For ODALS, see THIS FAA AC in *.PDF format.

For runway lights, THIS FAA AC has the details you need.
