My Jetbeam MKIIX beamshots and runtimes

Got my Jetbeam MKIIX today, post beamshots here and compared with another popular 1AA light-L1D CE!

Ok, you may want to know lux number first,

Alkline battery
100% output: 1020 lux@1m
maximum output: 655 lux@1m

NiMH battery
100% output: 971 lux@1m
maximum output: 575 lux@1m

14500
100% output: 2720 lux@1m
maximum output: 1885 lux@1m

at 5m distance, left to right: alkaline-100%, 14500-maximum, 14500-100%, L1D CE-alkaline-high


at 10m distance, left to right: alkaline-100%, 14500-maximum, 14500-100%, L1D CE-alkaline-high, L1D CE-alkaline-turbo, L1D CE-14500


Runtimes:

Re: My Jetbeam MKIIX beamshots

Very nice pictures. It seems from the picture MKIIX is bright when its in 100% mode. But with its UI, it a pain to get to it. Then again in real life who need such a bright light right.....(now the whole forum is gonna kick my butt - hehe)

Re: My Jetbeam MKIIX beamshots

Thanks for the pics Chao, i really like these real life comparison shots. Did you notice MKIIx-alkaline-100% have more sidespill than the L1D-CE (high)?.

Basically i would like to know whether the MKIIx looks dimmer due to increase side spill, or is just overall dimmer than the LID-CE.

Thanks in advance

Re: My Jetbeam MKIIX beamshots

I think my MKIIX-alkaline-100% still has less sidespill if compared with L1D-CE-high, or in other words, MKII-alkaline-100% just overall dimmer (not much)than the LID-CE-high, I don't have the overall output test, just according to the pics and my eyes observation.

My brief conclusions are MKIIX would be a nice bright light for 14500 battery, and indeed the UI in MKIIX is not convenient.

Re: My Jetbeam MKIIX beamshots

The doors are more iluminated with de beam on mkIIX at 100% on 14500, I like that kind of spot.

Re: My Jetbeam MKIIX beamshots

can you please do some 14500 runtimes?

Re: My Jetbeam MKIIX beamshots

yes, runtime graphs added, alkaline in 100% output run over 90 min, not bad, however on 14500-100%, regulation looks fine, just the runtime too short (14500-maximum is on the way!).

Re: My Jetbeam MKIIX beamshots

14500-maximum runtime added.

Re: My Jetbeam MKIIX beamshots

impression performance from this unit. thanks Chao.

Regulation on 14500 is superb !!!

Thanks for doing those runtimes Chao. This is an amazing light. Really performs well.
The 100% is actually easy to aquire. If left in advanced mode, all that is needed is a hard click for on then hard click for off. The other modes are just a soft press away and always reverts to high except on the strobe/SOS modes.

Thanks for the runtime graphs, so it looks like the MKIIx has considerable more runtime than the L1D-CE, this may be the reason why it has less overall output in comparision to the MKIIx

Add NiMH runtime at 100% output, around 150 min regulation.

Just post another comparison, beamshot pictures all used alkaline batteries, runtimes used NiMH batteries.

Hmm, I wonder what the overall light output is for both. Is this done with a lightbox (similar to Flashlightreviews)? Or just shining it directly on the meter? Either way it's dissapointing to see that the mkIIx is only about 30-40% more efficient (mkII is 70% the efficiency of mkIIx) than MkII. I thought the cree was supposed to be twice as efficient. Maybe I'm wrong.

I don't have light box for overall output test, I just got the number directly from meter at 1m diastance.

It would be good to see the overall light output to see what the result is. It's possible the increase side spill is where the light is going to. There is an increase run time that is part of the reason too. It would be good to see the MKIIx use a smooth reflector so we can see a closer comparison.
