Just curious, why do P7s use the soft rubber like (silicone) dome instead of epoxy? higher temps?
Why P7 emitters uses soft polymer domes?

Just guessing but it might work better with expansion and contraction

I guess also better optical properties.

I think it's because it makes them more tempting to poke with your finger and cover them in finger prints. Just kidding.

For the same reason P4's are made with silicone domes.

This is just a guess by me but maybe the soft domes stay in place better. There have been reports of the hard domes used by Cree falling off. I experienced that myself.

Yes. I just colored one with a sharpie today. I think it's Silicone and if so, Silicone is 100% inert and nearly impervious to heat, making it a great choice for long-lived emitters that put out heat,
