Level 50 PvP IOs do keep their bonuses, even when scaled down to level 1.
LotGs have to be level 33 or lower to work in SC.
Alpha incarnate has no effect in Siren's Call.

Few Exemping questions...
Do lvl 50 PvP IO's keep their set bonuses when in Sirens Call ?
When using Lotg+rech IO's do they need to be lvl 33 or lower to work in SC ?
Does Alpha incarnate still effect PvP in SC ?
