    Anyone upgrade a Dive Rite LED RX2 lighthead?

    I have a working Dive Rite RX2 light. It has a 4x Luxeon Rebel LEDs and was originally rated at 880 lumens. It also has a rotary magnetic (H/L) switch in the lighthead. I have seen several threads upgrading the DR MR11 lights to modern LEDs, but was wondering if anyone has tried putting a...

    Another DR MR11 HID upgrade

    Before the mid 80s... most cave divers used handmade lights. ;) I do think carrying a back-up primary light is a good idea when experimenting with this stuff. ...A but more complicated that the old lead acid halogen lights..

    question on Battery Options

    Any danger in running the higher capacity 26650 battery to a Cree XML2-U2? I might send an email to Dive Rite on this. For some reason they only mention using the 3xAAA pack or an 18650 in their info card.

    question on Battery Options

    That's what I was suspecting. I think I might pick up a couple to try out in my BX-1. FWIW, they run a Cree XML2-U2

    question on Battery Options

    In my existing Dive Rite BX-1 backup lights, they require a sleeve for the 18650 battery. That sleeve is nearly the exact same size as some other spacer I bought that say they are to adapt 18650 to 22650 application. So why not just use the 22650 in the BX-1. Honestly, these lights are pretty...

    question on Battery Options

    I have been playing around with ideas for a dive light and was wondering why the 18650 battery seems to be so prevalent for battery packs vs some similar like 22650 or 26650? The Idea I have in might will probably use just 4 cells, and there would not be much penalty for a wider26.5mm cell vs a...

    Old Dive Rite HID can light

    I am pretty sure the pack to my other light is Li-Ion. I have not taken the shrink wrap off it, but it looks like 10x 18650 cells. That 13.6v is just what I spot checked with a cheap multi-meter.

    Old Dive Rite HID can light

    Yes, I guess my question was as to why you recommended the Li-Po batteries? Is it just the size/availability of existing packs? Or is there something about a HID light that makes battery type for critical? I assume I can get more power/mass ratio in something other than the original 12v lead...

    Old Dive Rite HID can light

    I am familiar with using Li-Po batteries and have several for my RC airplanes and Quads. So are you steering me away from using a Li-Ion 18650 pack? Why?

    Old Dive Rite HID can light

    I was given an older Dive Rite HID Can Light and was contemplating ideas to make it useful as either a back-up or loaner. I realize there are tons of better options with todays technology, so I am looking for low cost ways to make this useful for cavern or intro-cave dives. Nothing to crazy...

    Rechargable batt options for Hollis LED3 & mini3

    The cost for the Eneloop Pro does not seem to bad, but they are rated for only 500 recharge cycles. For dive lights, I suspect, I would be more than happy to get the 500 cycles out of them, but my concern is keeping track of how may cycles each one has had. For cave diving, most of these...

    Rechargable batt options for Hollis LED3 & mini3

    Does anyone know if I will loose brightness using the Eneloop batteries vs the alkaline batteries? I don't seem to see the voltage posted for the Eneloop or E Pro batteries But I assumed they were 1.2v like the other NmH batteries I see. It might be ok if they hold the peak voltage longer than...

    Rechargable batt options for Hollis LED3 & mini3

    Keep in mind, both these lights use 3 cells that bundle into a holder and slides into the body as if it were one large battery. So The LED3 essentially runs on a 4.5v battery pack made up from 3 AA batteries. In the case of my Dive Rite BX-1 Lights, a delrin sleeve/spacer is included that...

    Rechargable batt options for Hollis LED3 & mini3

    I have 5 divers in the family and we do mostly Spring/Cavern/Cave diving at this point. I was looking for a good option for cavern primary lights with push-button switches and found a good deal on some Hollis LED lights locally. I got a couple of there LED3 lights that run on 3x AA batteries...
