    Posting Notes for Puzzles Solved But Not Found

    in General geocaching topics

    Posted

    I have a "SOLVED, TO-FIND" puzzle bookmark list. I'm also working on a few puzzles where the physical final is located quite far from my home area. I've posted notes to those cache pages, never got a complaint

     

    I also own a few puzzles and would LOVE to have people solve and post notes or bookmark. Why on Earth would a CO not want that? Perhaps there are reasons, but I can't see what they'd be .......

    See the post by HKJ in this thread on candlepowerforums (a GREAT board, by the way) for an explanation of why an 18650 is essentially equivalent to two CR123s. Bottom line is that all LEDs yield max lumen output at some voltage below the peak they can tolerate. Past the peak, more volts do not yield more output. For many LEDs (like the TK-11 R2 I own) the peak lumen output occurs at around 4 volts. (This relationship is essentially why a 4D maglite has roughly the same lumen output as a 6D. Don't quote me on that, as I don't know a lot about Maglites. I own a 4D and it would be great for whacking an assailant, that point made above is true!)

    Here's the chart he includes just in case anyone can't access the thread:

    And his point about the CR123s rattling around is true, too. My TK-11 R2 feels much better with the 18650 in there.

     

    I actually just took the light outside just a few minutes ago and did some beam-shot style comparisons on a neighbor's tree (maybe 60m away). With the 18650, the light was, in fact, a bit brighter. But the 18650 was fresh out of the charger, so I'd call it a draw.

     

    Cool thread, always fun to talk about flashlights and night caching!

    Regarding the comments on "too much light" from flashlights and "cost of CR123 batteries":

     

    You can definitely have too much light, I agree. I typically wear a Petzl headlamp that puts out something like 45 lumens and I have the TK-11 R2 in a holster attached to my belt. When you need/want to look way down the trail, the much brighter light comes in very handy. Throws a long, penetrating beam. When you can't tell which branch of the trail has the Fire Tacks, the brighter light helps out.

     

    I use rechargeable 18650 batteries, because of the cost of the CR123s. But that's a good point, too.

     

    Good thread, always fun to talk about flashlights and/or night caching.

    What flashlight do you take caching?

    Repeating myself and contradicting my love of bright lights ... but whattheheck!:

     

    Really bright lights are actually bad, IMHO, for doing night caches that use Fire Tacks or other small reflectors. It is amazing to see from how far away the reflectors can be seen with only a low amount of light ... night caches have a better, more mysterious feel when you only have a small amount of artificial light ... bright lights really destroy your night vision (pupils constrict like mad when a 200 lumen light comes on) ... etc.

     

    Go when there's a new moon! Go when it's cloudy! Turn off your light(s) for awhile and listen to the forest!

    Vote early and vote often! I guess you do like Fenix. I was looking at the TK11 or the Olight M20 Warrior for a really high output light. How is the quality and sturdiness of the TK11? Ever seen the other brand?

     

    630 lumens may melt the cache or set fire to the log!!!

     

    Hmmm, guess that's one of them thar duplicate posts ... well, double-duplicate! ... but, the TK11 R@ is worth a few praise-posts!

     

    I do not know the Olight M20 Warrior, or even the brand Olight. I'm actually not a big flashlight freak ... "flashaholic" I believe they're called. I've started going out hiking or caching at night or pre-dawn more now and so have gotten into it a bit. Check out candlepowerforums.com for the real flashaholics. You could probably find or get a review of the Olight over there.

     

    630 lumens is a lot of light, you're right. Burn time is 2 hours ... looking forward to it!
