Despite Henrik's graph would probably match better if the NCR18650BL cell were have been tested on the newer 4-wire battery holder test station, capacity still does not match even if cell curve shape does.
So it is not an NCR18650BL. There are cells Henrik still have not tested, the one Sofirn is rewrapping could be some 3100mAh 0.2C rated cell from some known manufacturer like an NCR18650A, or from another OEM.
Thanks for chiming in Petr J., it is praiseworthy for Sofirn to preserve the original OEM wrap under their own; helps us consumers identify the product besides adding extra insulation.
That DLG “INR18650-B32” cell looks to use similar chemistry to that of the Sanyo GA/BL cells, with a little less capacity though. Good standard drain cell I'd say.
I like the light and tint, but I can’t understand why there’s no long click from off for moonlight. This light with an added moonlight mode only accessible from off would be perfect
choice of luminous color is purely a matter of taste
out of only this two personally i would prefer definitely the 5.300k one. the 4.000k version has a strong visable orange yellow tint which bothers me in fact.
some people may love particularly that. well i don’t… i like it way more neutral.
and at the best with high color rendering skills:
but that’s just me
I prefer it more neutral too, and that Emisar D4’s color looks nicest to my eyes. eg. by comparing the colors of the yellow bird between the images.
So that makes my choice easier: SP40 5300K. The SP40 4000K’s orange tint reminds me of incandescent flashlights, which might be nice for relaxing but less so when trying to see or work on something. They might both have their uses. I wonder what the SP40 3000K looks like.
I got mine on discount a while back and I think it was the the coolest tint in the lineup. I’d prefer a warmer, more neutral option, but the price was right.
Has anyone measured an SP40 in their “lumens measuring device”? I’ve just measured mine in my DIY sphere and the numbers seem really low (while many of my other “calibration check lights” check good with my past values). I don’t expect my lumen values to be exact, but these seem really low. Mine is the 4000k XP-L.
I’ve measured:
Low = 6.6 Lumens
Med = 62.8 Lumens
High = 306 Lumens
Turbo = 798 Lumens
I’ve also measured my SD05 on a brand new Molicel P42A 21700 @
Low = 277 Lumens
Med = 792 Lumens
High = 2,223 Lumens
I’ve not looked up anyone’s verification of lumens measurements, but I seem to remember high should be around 900 to 1,000 lumens.
