While having another DT70 working with unprotected flat top, I used their batteries in the XHP35. The experience is similar & different:
- it’s similar, because also this one does not blink every 10 seconds, but like the XHP70 every second
- it’s different because it changes from “on” to “blinking” at 3,63V - so in this case the 50% seem to be real. Based on this also the last changing level (the above mentioned 9%) seem to realistic - after blinking red I measured 3,02V
Conclusion:
- the type of signal does not correspond to the manual
- the XHP70 seems to signal the levels wrong
the XHP35 seems to signal the levels right
Regarding the XHP35 I just recognized another point:
While running at about 1.200 lm the MT09R gets hot - and I mean hot in a way you do not want to hold it in your hand. This is - from my point of view - interesting, because we talk about a quite low energy level. While running the XHP70 at the same level I did not even recognize a raise in temperature.
Hopefully this is just another indicator for a faulty driver…
Interesting. If the 35 gets too hot, it means the batteries are being drained, although the led is not getting the most of it. This could be tricky, but the batteries are not exceeding safe discharge rate and temperature as the Imalent cells are protected 30Q. But this driver is going to be replaced anyway. Thanks for the data!
Which from my point of view can be the problem of the actaully delivered XHP35-Version with the output at 3.500 lm and not at the specified 7.500 lm (or actually corrected 7.000 lm).
It seems like there is something in the driver that consumes the power instead of bringing it to the LEDs…
Nope, the IMALENT was running on unprotected LG HG2 - which in this case also do not have a problem with the current. And if you ask yourself regarding the DT70: it’s one of my last ones which has spring contacts in the tube - the actual versions run on protected AND unprotected cells…
Official GB shipped directly by Haikelite closed two weeks ago on 31/01/2018. See GB thread here.
Terry who now represents Haikelite in US and Canada may still have a couple of lights available for sales, but he only ships within US and Canada. If you are in US/Canada, you can order from his website, He Said She Said Sales.
Well I got two sets of 30Q charging; one set in the Zanflare C4, and the other in the VP4. Tracking says that my lights will arrive tomorrow, woot! :sunglasses:
There is an odd bug on both my green and khaki 70 versions. I think (hope) it’s just a minor error in the battery indicator section of the programming firmware.
When batteries are depleting and battery indicator starts blinking blue, which means voltage is about 3.6V~3.7V, then the battery indicator blinks on level 1 till level 4, but on turbo the battery indicator remains solid. It behaves like this until batteries are depleted until ~3.0V and battery indicator turns to blinking red for all levels from moonlight to turbo.
Anyone with the same phenomenon on their 70?
I will double check but I'm pretty sure about this.
Turbo is set up so that anytime it steps down you are able to kick it right back into turbo regardless of heat. Basically if you make it the light will bypass the heat and power output that goes with keeping it in turbo even after step down.
This is not a step down from turbo related phenomenon. It’s about what the battery indicator does as a function of cell voltage, and on what level of output you are. The battery indicator should be blinking blue below a certain voltage, but remains solid when in turbo. It’s supposed to be blinking too.
