    I just finished the book "Dress For Success" by Dan MacKay. A lot of useful and comprehensive information.
    The book was written in 2011 and I think the chapter on lights may be outdated as it mentioned only HID and Halogen lights with canisters.
    With the recent developments of LED lights and LiPo Batteries, does a Light & Motion LED light with a hand strap is considered DIR? It has the same luminosity and burn time as those canister style lights...

    Soft Goodman handles are no good.

    No L&M or cordless light has the same burn time as a canisters light at the same brightness. Even the smaller Slimline diverite batteries are getting 6+hr on high. I have a L&M and a big blue and neither are even close to that on high. Maybe an hour on my L&M.

    I can't speak for anything DIR acceptable because I went a much different route but I love a soft Goodman. Beats the hard handle IMO.

    Ability to remove it quickly and efficiently from your hand. Ability to continue using your hand that is holding the light. Soft handles impair both of these.

    Could not be more accurate. I had the soft goodman that came with my HP50 and dealt with it for a few dives. I then swapped it out for a LM hard goodman with the Dive Rite QRM mount and it is awesome..

    Put a thumb loop on it and it will even be better :)

    Twist on head backups remain the most reliable too. I have some pretty nice rechargeable li-ion LED backups which I have started carrying for caves personally - in part because they are way brighter and I can exit faster with them. I still have at least one twist on backup with good old alkalines on my harness.

    2004. By 2011 Dan was long out of the diving game.
