They do, but your eyes are not that good at measuring it. The difference between 5k and 6k lumen is hard for human eyeballs to see especially when you have to take a break to change out the batteries. You have to remember what the first brightness level was as your looking at the second brightness level.
A lux meter would definitely see the differences as would an amp meter measuring the current.
Iām talking high-drain only. If you try 2 vs 4 regular cells, you probably will see a difference. Thereās also a difference between 4 regular and 4 high-drain cells, though you probably wonāt be able to tell with your eye between battery changes.
Also, the battery voltage makes a huge difference. Youāll only get full output if your cells are fully charged to 4.2v.
IIRC, PWM is used for all modes, unless youāre right at the output max for the 7135 or FET. Itās very high frequency, so you wonāt be able to see it. Perhaps you might notice on moonlight, but thatās probably the only mode.
Gotcha, thanks. Yes, I understand how difficult it could be spotting a difference in light intensity with a naked eye, definitely could use a lux meter.
There is even a special flashlight app for that: search for āceilingbounceā. It makes use of the same phone sensors as the various luxmeter apps so in accuracy it is not anything special but it has all sorts of nice features that makes flashlight measurements more convenient.
Great idea! I have went as far as installing a couple lux meter apps, but I didnāt find a suitable piece of semi-transparent material to cover the sensor to prevent it from saturating. Totally didnāt think of bouncing the light off the ceiling.
I have two of them, and on one of them the green light on the button started to flicker and eventually stopped working after the first week or so. Not a big deal, still works great, and I love the Q8!
Lol sb, I thought you were replying to raccoon city. I thought, at first, you were talking about having two trolls. I really need to switch to decaffeinated coffee.
I have a question - how does stepdown act when in ramping: for example what does it do when itās set to about half output and set to 5 miutes stepdown? what about thermal stepdown? I know it steps down on turbo according to settings, but what happens at lower levels? Thank you!
So the new way to reduce the post count to reduce the srver work load is to delete members accounts?
I best start behaving. There was an issue with switch lights earlier on that from memory were fixed by reflowing the items on the switch board itself.
At half-output, I donāt think it will step-down at all. If more than that, it will step down to about 50% output. For thermal stepdown, I donāt think it would do anything on lower levels because it wonāt get hot enough. Though, I suppose if you calibrate it for thermal step-down at a very low temperature, it might drop down when it doesnāt really have to.
I just use the default 3-minute step-down, which seems about right for fully-charged batteries. When the batteries get to a lower voltage, it never really heats up much at all, since output is a lot less. So, maybe thermal would be a better way to go.
Yep. Itās SBās world and weāre just living in it.
Seriously though, SB gives everyone a lot of rope. Itās very few people that are so disruptive and disrespectful that they actually hang themselves. Even then they sometimes are allowed to stick around. So if SB actually has to kick somebody out, you know they messed up big time.
That was just a temporary fix that eventually failed. Thereās a problem with the switch pcb and the through holes (vias). The only sure way to fix it is to swap to a different switch pcb.
Very true. We are all given the benefit of the doubt here, by a large margin. Most of us respect that, or learn to. Only a few donāt, and then they go bye-bye. It keeps this forum a great place to learn, meet internet friends, kill time, and of course, spend some money.
