Well... revisiting this thread. Because I want a brighter strobe now. the Princeton Tec one just doesn't seem bright enough.
anyone got suggestions for a replacement?
I didn't have very good luck with the PT Aqua Strobe. I bought two and one leaked on the first deep dive. Other one is still OK. I bought the pair on a deal and mainly because they were small and packed light.
My other heavier models are doing well. The ACR Firefly is very bright and durable so far:

The Tektite is also doing well and is very bright as well but you have to be careful when shutting it off. Turn the cover too far and you will expose an O-ring:

Just bought this little fella the other day but have not dove with it yet. Looks very beefy and light. Moderate power. Has a little doodah for attaching it to a hose or with a little fiddling, the top of an SMB:
