Just saw this. sorry for the delay.....I don't know the actual burn time....havent tested itGqllc007 - Any chance you know the approx. burn time from flat for your S2? how long the battery last? Have you ever let it run in on position (strobe setting) until it dies?
Stuartv - I feel your pain. I have a demo BAF and plan to test this week in dark uw conditions at quarry. I also have a Trojan Classic II to test - also awful blinding like the BAF. I am waiting on an S2 to come to me.
