I have the bigger one (only difference is it holds more batteries)... the sucker is bright, I can't even compare the light it puts off to what my PT bulb light does... for the money, I don't think you can do much better.

<DIV>I have this as a backup light:

<DIV>And it's just about as bright as the full blown PT LED under water up close. From farthur away you can tell a difference (out of the water anyways) between it and the big LED light, but it's still blows all the normal bulb lights away.</DIV>
