Keyword(s): Dive Lights – Gear Comparisons
Have you ever had a dive buddy forget their light, borrow your backup, and—poof—it’s gone forever? Yeah, me too. In my case, it was my daughter (excuse me, “dive buddy”) who somehow misplaced my trusty Dive Rite BX2 with the new QRM mounts. Thinking back, I should’ve given her my Goodman soft mount glove while I was at it. What do they say…hindsight is 20/20?
Since she’s 14 and just starting to build her own gear setup, I figured it was the perfect time to take stock of what’s out there. And holy cow—there are more dive lights on the market than ever before. Brands I’ve never heard of, endless specs, lumens, batteries, charging quirks… it’s enough to make your mask fog.
So instead of getting lost in the dark (pun intended), I pulled together a head-to-head comparison of today’s leading dive lights. Measured across 8 key factors—from brightness and runtime to safety and value—this guide will help you cut through the noise, find the light that fits your diving style, and avoid buying gear that’ll end up collecting dust. I hope you will like our article, “The Ultimate 2025 Scuba Dive Light Comparison: 8 Key Factors.”

📝 Final Thoughts
Recreational Night Divers:
The OrcaTorch D710 and Dive Rite CX3 are top-tier primary lights, while the Mares EOS 25LR and Bigblue AL1300NP are great for their compact size and versatile beams. I typically try to keep the gear consistent throughout my dive bag. It makes maintenance, operation, parts, and service easier. Probably most importantly, familiarity with my equipment stays fresh in my mind. If I were to pick up a backup light from a different manufacturer, the SeaLife Mini 1200 seems like it would be a good option.
Technical/Wreck/Cave Divers:
The Dive Rite CX3 (with its super-long burn time), Bigblue AL1300NP, and UK C8 are the best options.
On a personal note, I’ve had nothing but exceptional interactions with Bigblue’s service department. I own an earlier version of their 9000VTL, and after six years, the battery began losing runtime—not drastically, but noticeably enough to be noticeable. When I contacted Bigblue, they were incredibly supportive and made it easy to get a replacement. That kind of long-term customer support speaks volumes about their brand. They offer narrow, penetrating beams, long burn times, and rugged reliability.
I also had an exceptional experience with Dive Rite’s service department, which was outstanding. I once had an issue with a wing that was completely my fault, and when I reached out, they simply told me, “Send it in.” They fixed it and sent it back—an example of a company standing behind its gear.
I am not affiliated with Bigblue or Dive Rite in any way other than as an ordinary customer, although I would like to be…hint, hint, nudge, nudge. My experiences with both Bigblue and Dive Rite have made this comparison difficult to be objective; however, not impossible.
Instructors & Guides:
The Mares EOS 25LR is perfect for this role, with its unique laser pointer for effortless signaling.
