which HID should I choose?

I’m looking for a reliable HID dive light for night diving.

Now I am considering taking Brightstar darkbuster 24W or UK cannon 100?

What do you think about the brightstar one? Had anyone used it before?

I like darkbuster more brighter with 1750 Lm than cannon 100 only with 450 Lm.

I would like some recommendations. Thanks guys.

Neither... I choose a canister light, so I can actually use my hands without needing to juggle a big huge light as well.

Used 10w can lights go for around $300.

And the high quality of most canister lights means your light will likely be far more reliable than the Brightstar and light cannons.
