Hence my "Caveat #1" above: the Lightspeed is NOT a good choice for this approach. The Lemo version does not have the capability to automatically switch to batteries if panel power is not available. For this reason you want the Bose A20 or the David Clark DC ONE X (the latter is my choice--built like a brick ****house, legendary DC service, if the ANR fails it doesn't get stupid noisy so not a mission fail).
Do different brands require specific LEMO to GA/Heli adapters?
Negative. The Lemo (aka Bose) connector configuration has become an industry standard.
