is not good for lights. Mine died super fast at Nationals, and Mark was using spare headlamps on the bike. We were really happy to pull into that bike drop TA for more than one reason.

Yeah, I'm looking into it. I got the Zebra overnight stuff...and maybe it's only an issue in the cold. I am researching it, and also have reached out to Zebralight. Funny, because it's a lithium battery and thought that it would perform better than alkaline. Glad I am figuring this out now...

Perhaps the magic shine 's weakness of cable clutter is then a strength as it keeps in a pack or pocket protected.

I have used my zebra light in extremely cold weather and it worked fine. Do you have it on the highest setting?

Work4justice:
Yes I did...but it is purported...and during other activities seemed to last forever...

Why wouldn't one run on high ?!?

Tone:
I never do.

Hmmm so far ive had no issues with cold on my zebra light also. Could be due from all sorts of problems. even we did the 50k you seemed to be having issues with it I noticed. Maybe its just a lemon? And you can exchange?

Maria and Tony are just hotheads.

I never ever run on high for any of my lights. It cuts the battery life significantly (down to something like a third or a quarter depending on the different settings.)

Medium is about the same amount of like as any $40 light at REI that runs two AA or 3 AAA batteries for 60 hours. High isn't any brighter than a MagicShine medium, which is 5-6 hours at say, USARAs, with one of its standard packs.

Unless Tony is talking about High subtype 2a or 2b or 2c, which might be passable? Although I had trouble making out a dog I knew was there at 20 m on high high.

Which medium are you talking about? There are 3 levels. Level 1 has two levels which are super low. Pretty much useless for trekking but works great for close reading at night. Level 2 has two levels that I usually use for trekking during races. Not bright but enough for slow trekking. Those two last a while. Then level 3 has 3 levels and then burst mode. The lower level in that group is plenty bright for trekking and singletrack riding. My battery usual lasts several hours at that setting.

I have the headlamp version in a regular flashlight. The beam spread is a lot different between the two. The headlamp is more floody than the flashlight. I use that flashlight for biking. If you are looking for a low lumen light with a lot of throw then you got the wrong light.

My guessis the Magicshine has more throw. Is the Magicshine battery pack a single battery?

No, four glorious batteries stuck together. Either 4400 mAh stock or optionally 5600 mAh iirc.

Yeah..... what Tone says. I think W4J just has a lemon. I would exchange it.

Go zebra lights!

50% lemon rate? Or a design that just doesn't work well with cold temps? (exposed metal housing that is probably better than MS for summer cooling) Maybe I can get my mother in law to knit a cozy.

Messaged them...I'll let you all know how it pans out. Fyi...put my batteries on the chargers morning around 8. One of them still isn't charged...maybe that's the problem.....

Cozy... hilarious

Omg, PLEASE get a knit cozy for your headlamp! LOL! That will be awesome.

The problem with some of the newer batteries is the insulation sticks out to far. Then the charger metal end isn't long enough to make it past the insulation and contact the end of the battery. I had to put a piece of metal between the charger and battery in order to complete the circuit.

Can't see what design works well in cold temps.

I have the flat topped batteries and it did charge...my battery recharger has a spring.

works in cold temps

remote batteries, warming themselves in a pack or on one's person

I meant in a single unit. If you are using a light with a separate battery pack during your training they aren't so bad. But in adventure races where you are constantly changing disciplines they suck. Especially if the battery pack is to heavy to mount to your helmet. Which is the case with the case with the Magicshine one.

I'm making a cozy.

'Bent found a two battery pack with good run time, could be helmet mount.
