Should I pick up some of the regular white ones?
...
Is this kind of fatal drain common with flashlights?
No, and Yes
It is the responsibility of the Operator, to check the voltage on their rechargeable batteries.
I use Eneloop and Eneloop Pro in my Massdrop AAA Tool. When the battery gets weak, I cannot access High Mode. That is my hint that it is time to recharge. At that point my batteries tend to test below 1.2v
It is not required that Eneloop/pro be drained completely before recharging. It is better to recharge earlier than later.
When using rechargeables in any light, it is the responsibility of the user not to overdischarge, by checking voltage, watching for dimming, and NOT leaving the light on for 30 hours
ONLY disposable batteries should be used for 30 hour runs, if that is something you enjoy. Personally, though I respect the use of sublumen levels, I have no need to drain my batteries completely. I do not use disposable batteries.
You may have been confused by discussion about cockroach lights running at sublumen levels for long hours, using disposable batteries.
When you use your Yuji C01's with rechargeable batteries, just change batteries when the light gets dim. And I suggest you add some sort of Voltmeter to your kit, so you can use rechargeable batteries, knowing their Voltage levels.
I find a Voltmeter extremely helpful to have. I highly recommend you add Voltage monitoring to your Eneloop/pro user experience.
Just for you Jon, I know what a tint comparison junky you are :)
Thank You!
Your photos are truly excellent beam comparisons, for several reasons
1. By lining up 3 lights, with one of them being cool white, it gives a very good reference for comparison of the tint (color temperature) of the two Yujis
2. By lining up warmest on left (color temperature), next warmest in middle, and coolest on right, your photo makes it easy to see the change and progression of the 3 different CCT (color temperatures), and Tints (Orange, White, Blue)
3. the beams do not overlap, in the animation, which allows us to see the shape of the entire beam includingt any hotspot, plus the size of the spill. In this case the Yujis demonstrate their Aspheric beam and diffused spill, similar to a Mule, in contrast to the partial focused but relatively wide hotspot, with small spill, of your cool white Nichia-GS on the right.
one of the benefits of the Yujis, since their color temperature is known, and because they have high CRI and high R9, is that in the future they can be used as excellent reference lights for beam photo comparisons.
I like everything about the LED selection in the Sofirn C01, including the beam shape, tint, and color temperatures. Im particularly interested in the 5600k High CRI experience, which will be new to me. All my other High CRI lights are warmer.
I predict that years from now, the C01 will have Cult Following, not unlike the great cockroaches upon whose shoulders the Yuji C01 stands. There will be two subcultures, the Warm one, and the Cool one :-), although most people will buy both.
Jon,
That's a nice way of saying Tint Snob.
P
Indeed!
And Proud to be in good company ;-)
I like Warm Wide beams for close range and low lumens
I like Cool Narrow beams for longer range and higher lumens
I have not received my Yujis yet but this is my anticipated use
The warm Yuji will make a great bedstand light, and for times when the white balance of my brain is at its lowest levels (fully dark adapted)
The cool Yuji will make a great EDC for times when my brain is adapted to cooler light, including during the day.
