Look at how the T70’s XHP70.2 NW brings out the details of the subject , IMO, a perfect combination with an orange-peel reflector, a gloriously smooth, wide hotspot of neutral white led goodness. Both shots at 60ft (18mt) away.
I checked the Wuben T70’s oem 26650 cell and displayed an IR of 72mOhm, and on its way to being fully-charged for a Discharge test.
Next, I will discharge it to 2.80v at 7A, the highest discharge rate my iCharger can handle and see what happens, and how much capacity will it give.
Edit: iCharger ready and waiting for the cell to be fully-charged for a Discharge test… set to terminate at 2.80v @ 7A rate:
Edit: Discharge test started; 7a rate is not accepted, iCharger will only allow 4.0 of Discharge rate…even if set at 7A:
Edit: Discharge Current goes up to 4.4a as cell’s voltage slowly depletes after 10min, 43sec.:
Edit: 4.9a after 30min, 2,269mAh:
Edit: 5.1a after 40min, 3,115mAh:
Edit: Discharge ‘Done’ at 55min, 30sec, average Discharge Rate: 4.5A, Discharge Capacity: 4,422mAh (not bad for an oem cell Discharged continuously at a minimum of 4.0A to a high of 5.1A! (the 3.37v is the resting voltage, after a ‘bounce back’, of the cell after it was set to terminate discharging at 2.80v)
Perhaps Wuben re-wrapped a decent Medium-drain 26650 cell and is actually enough for the T70’s power draw requirement.
Tomorrow I will do another Discharge test, this time at a rate of 2.5a in the same hobby charger, and see how much capacity difference, if any, exist.
Edit, one day later: This test will tell us how much Discharge capacity difference between a cell that has been Charged relatively Fast (2.5a) then Discharged at an average of 4.5a, and from a cell that has been Charged slowly (.3A, using my MiBoxer C4-12, set manually, rested about 8 hours, resting voltage: 4.14v), then Discharged @ 2.5A:
Edit: 1min, 42sec from starting point of the 2.5a Discharge test:
Edit: 1hour later: 2,526mAh
Edit: at 1hr., 46min, the Discharge session already stopped, showing ‘Done’ at only 4,444mAh! So surprisingly an increase of only 22mAh from last night’s ‘torture test’ result of 4,422mAh!
It looks that the oem rating of 5,000mAh is about 600mAh over-rated, but still capable of continuous 5A load, which I believe is good enough for the light’s requirement.
