Princeton Tech Standard vs. LED

A 1$ cylume glow stick will do the job if you just need it for the class. Otherwise, you might find a Glo-Toob a better investment, as you can use it as a tank marker, signal strobe, reading light, or distress signal.

I second that, I've used mine for so many things from backpacking trips to reading maps on the road, plus the kids really like diving for it at night in the pool.

I hate the switch and the switch even broke once to boot. PT fixed it for free. But the switch is still what I call "user not friendly". You get used to it though and it's not as bad as I make it sound. I normally take my UK Light Canon even in clear water just becasue I like the UK switch so much more. Clear water daytime diving, is when the PT should be used though. Good light still. I say get the LED if at all possible. You'll be glad you went ahead and got the good one. Maybe check into UKs top of the line LED light. If I were doing it again, I'd check that out before buying first.

another vote for LED, not a fan for the design of the switch either..
