Erm... would that be 1p24b?

They are, to be sure... though they take a lot of drive voltage and a lot of bias: they're not very sensitive.
The devil in me says, build up an audio amplifier, immerse it in Fluorinert liquid (I've got a couple of litres!), screw up the HT to 200V and the Ia to 50mA each, and see how long they can blast-out 10W of high-quality audio. (After all, if they can push out 800W pulses of RF...
)But I just can't bring myself to treat bottles as I can, encapsulated impure sand...
