    Either you would be pretty limited in burn time or else you'd have to have a fairly large canister. Doesn't seem worth it unless your taking pictures or video. Disclaimer: I also still have a 10 Watt, so could be considered old fashioned

    No, "old fashioned" is still having a 50W halogen light

    Naa, old fashioned is a 30 watt sealed beam neck light with a square motorcycle battery canister. I will sell you my "Bob Axlerod Special" if you want.

    Default 50 Watt Rules

    I took ARY's 50 watt homemade HID in a sidemount cave we were laying line in to shoot some video and the one thing I can say is you wont miss any side passages in small cave with a light that big.

    Default 50 watt light HID

    I have one of these lights but use it sparingly:

    it does hide the lights of divers behind me. For safety I prefer to be the rear diver all the time

    it is too bright for small areas, great for large rooms

    you can take non flash photos in caves which can give more realistic cave pictures of what we actually see / experience

    it will blind oncoming divers such much they will find you after the dive

    you will get noticed.

    it's fun to use and see more things

    As easy to carry as any other light

    Haha.....

    Seems most people don't like 50w HID

    All my buddies want to change to a brighter light (we are using 18w & 21w now) as the rock on some of the cave here are black in color.

    So, are there any big difference between 21w & 35w?

    You have to double the wattage to get one f-stop difference in brightness.

    Not really.

    10, 21, 35, 50w doesn't matter - your rocks will still be black.

    Oh so thats your light in the cave diving museum! lol

    I know I chose Barry to interview for this video but if you want to learn A LOT about canisters, NiMH vs Lithium and HID vs LED take a look at this video, its informational.
