Looking for a light for day/night Keys diving. - to look under reef overhangs during the daytime for those hiding groupers, etc - bright (>500 lumens) - good run-time - like an hour before the lumes start dropping off - uses commonly available batteries that I can find at Publix, etc. (C's, CR123A's, etc) - small/compact - something I can clip to my BP/W and it stays out of the way and doesn't drag on the bottom Was thinking along the lines/dimensions/performance/cost of the DGX 600, but it has wonky batteries (21700s). Would appreciate any thoughts! |
| Take a look at the OrcaTorch D530. It is my backup light for cave diving, but my primary for night ocean dives. It is solidly built and is on sale on Amazon right now for $85. It doesn't have one of those stupid high-med-low-strobe-SOS-off switches that makes you cycle through them all. It has high-low-off. I ran it for 1 hour and 25 minutes straight and the brightness stayed the same. Then it dropped off to about 100 lumens. It uses commonly available and cheap 18650 rechargeable batteries. The included one charges directly from a USB cable and doesn't need an extra charger. You can't beat the power in lithium ion batteries, but if you really must have something with disposable batteries look at their D580. It uses either 3 AAA or an 18650 and runs for about 3 hours, but it is only 500 lumens. Best of both worlds I guess. Tie a bolt snap to it and it seems to meet your criteria. I don't care for the rotary switch though. |

18650 / rechargeable open up so many other options. Many will come with a very compact charger, some flashlights that are primarily 18650 will also run on two CR123s. Honestly, you charge up so many other things. Phone. Dive Computer. What's one more? And if you carry the right gear it may be easier to charge the battery you have than find the battery you need in a store. Absolutely your choice. Just saying don't limit yourself unnecessarily on a compromise that may not be a big a deal as you think. ETA I purchased this light, battery, and charger kit. It's worked well for me.

I have the red light TinLeg mentioned. My cave backups are DiveRite CX2. They make a great recreational light. Long burn time. |

It is my backup to my backup for caves. It is plenty bright and well constructed, but I hate the high-med-low-SOS-flash-off cycle on the switch and since there isn't a lockout mode I have to unscrew the head slightly to keep it from turning on in my pouch. I should just replace it, but I am saving up for a Shearwater Perdix 2.

It’s pretty standard. I only ever use the high setting. |
