No. I have used a couple Suprigs for supplemental lighting for GoPro and they’re only OK for that. Failed a few times or gets stuck on “flash”. Barely adequate for your purposes in clear water. Your jury rig idea not OK for primary light. Not, never for primary dive light. No.

Not a good item to go cheapo on. If it fails you’ll be pretty impaired in your diving. Good suggestions here. Underwater kinetics and Princeton Tech made good lights I still use a decade later. LED makes big difference in battery life. I like the DGX too.

Having a powerful beam is often overkill but sometimes it’s real nice too. Some can switch to lower setting.

Always bring a back-up light.

BigBlue has good rep. Not cheap.
