Have you opened the Head? How looks the pill? How looks the driver?
Yes I have. The pill looks ok. It has a screw-in reflector and it's solid.
The bottom of the driver can be seen in the photo above. It's press fit with the brass retaining ring. Note that the driver contains also the battery connectors, so replacing it is not an option. Stripping electronics away and using it as contact plate would be doable. [But the GB driver is good -> no need to swap - at least I won't.. ;) ]
I would love to have one that always starts in low.
did you measure the runtime using fresh charged NIMH batteries?
Aye, runtimes! How are they?
How about working voltage?
How deep cells will be discharged?
Same here. I might go for two.
What is the lumen sag on high, startup to 30 secs to 5 and 10 minutes?
Also like others said runtime and how low will cells get discharged
Edit:
Thats also a lower high then i expected, whats the current draw for the modes?
Also what type of driver is it, linear or buck?
I for one would not want one if it ALWAYS started in low.
When memory gets added in the final production, you will have to remember to switch it to low mode for it to come on in low.
Best of both worlds. At least I hope that's the way it's gonna be.
Same as above, always starting in low would be a pain if you always use it on high/med or need to illuminate something quickly (firefighter/security/police) without fiddling around with the modes.
If low is your most preferred mode then just leave it on low and it will stay on low.
I prefer starting on low every time, then i don’t have to remember what mode i let if on and get blasted by too many lumens in a small space later. However i can see your point of certain occupations or circumstances where mode memory would be a good thing.
Not saying starting in high is good either (or mid) but mode memory is a compromise of all of them.
For a small EDC starting always on low would be OK, I like it on my AAA and AA DQG lights.
the sample is still test type isn’t?i hope there is a solution for fixing this amnesiac driver :~
As the others have asked, the highest output only has 592 OTF lumens?
Always starts on low… is it “moonlight (0.4lm)” or “low (4lm)” to be exact?
Thanks and it’s getting more interesting!
If Ive read this correctly, and Im not rereading the thread so if I missed it, my apologies.
The TEST sample has no memory. But the one being discussed for the GB should have memory. It is one of the options requested by _ the _.
From the OP
“…- 4 modes, LL-L-M-H (0.2, 2, 25, 100), with memory, no blinky modes!”
As I understand that, the lowest mode is moonlight or similar being .2. And if high is 500lumens, then LL @. 2 (low low) is 1 lumen. (500*.2/100)
So how’s the group buy looking at this stage?
I would like 1, thanks.
Some answers to questions above..
1. OTF lumens
I think the drive current is a good compromise as is. 592 lm OTF is not bad at all, see the following comparison table:
The drive current could be made higher, but I wouldn't dare to give out that kind of light to a non-flashaholic.. It would simply become way too hot when left unattended.
2. Mode memory
The GB lights will have a good memory, which engages after being off about 2s (not more!).
3. Runtime, heat, heat sag..
I'm planning to perform the runtime tests this evening. Please wait.. :)
Preliminary result is that the head of the light gets quite hot after being on for about 10min. Body tube / cells don't get hot at all.
Thanks for update, the, good job ;)!
With memory if you leave it in low. Then it’ll turn on in low. Problem solved. If you are not leaving it low, then the reality is you probably don’t use low as much as you think.
And at the end of day if low really is the most important and used mode. Then picking a 4AA light is overkill and you’d be better served with a 1AA or 1AAA light.
Sorry but I don’t quite understand about this sentence. Do you mean that it actually behaves like the Nanjg driver, i.e. when switching it into high mode and stay in high mode for more than 2s it will memorize the high mode?
