Hi George, will these drivers be available for purchase? I’ve bought 3 of these and the last one I received worked for 30 sec. and the driver quit working…smell of burnt electronics. Sorry if this has been talked about already peeps. I had limited time this morning and want to get this puppy running again.
Thanks DB for pointing me to this thread! Are you in Austin?
Trying to figure out how that driver could have gone magic smoke on ya, seems likely you had a short somehow but George took precautions to prevent that. Which makes me wonder if something got jarred loose in shipment…
Hi George.
It is off topic but I can not resist to suggest idea for future flashlight. Zebra
18650 like titanium headlamp lighter and smaller than h600.
May be sound like a joke but how old are you?, some times the noise depends a lot of the age, I have the same flash light and I don’t heard any sound but I have 40 years old.
I will ask to my wife if she hear some noise she has better hearing than me.
My 9 yr old has heard bugs squealing where of course I got nothing. Young females tend to hear better than anyone, but young mother’s are scary with what they can hear even from a distance and through walls!
Once you’ve got some age on you, as a male, and after some years with intense audiology in a car and/or shooting handguns, there’s ALWAYS enough whine going on to cover a mere flashlight driver complaining. But not, sadly, enough to cover a wife going on and on (used as an example only, for clarification. )
Today is an anniversary date, 34 years ago today I married the wrong person.
I use my nw quite often and I don’t hear any noises.
I just had my wife take a listen, she hears nothing either.
But I have 30 years combined (3M,P&G) in loud manufacturing and I didnt always wear hearing protection :person_facepalming:
You can also use a sound editor to generate tones to pinpoint your upper hearing limit. I recommend Audacity—it’s free. Use the “Generate Tone” menu option to create a clip of a specific frequency.
I usually file or sand off the end of the battery tube to re-gain clean bare aluminum so that when assembled the ground is secure.
I also rarely use thread lube. Never on the tube to head contact and only sparingly on the o-ring. Try to keep the o-ring lube off the tailcap threads. I don’t like the dirty lube getting between my ground connection.
Hi, Kusie,
usually, I will source LED, cool white at 1A/B/C/D, and nature white 4/A/B/C/D, but usually nature white is not so easy to resource, so, 3 seires or 5 series also will install if cannot find 4 series at that time. for 26650 V3.0, first installed 5B tint (around 4000-4250k), later and current is 3C (4750-5000k).
about nichia 219b/c, first I cannot resource this LED, then I think more important thing is, the optics seems not so fit to richia leds, the hot spot is not clear and the lux is much lower than XPGs at same current set. so, that’s why there have no nichia choice.
yes, there does have a little drivers will make noise due to inductor, if you can do, dis-assemble it, find the inductor, resoldering it for a try (but it is not so easy to do), although the inductor is solid one, but maybe a little displacement will lead it verbration due to high franquancy.
maybe the problem is on the inductor not soldering well, the current cannot flow steady or other electric components let the regulator IC cannot work normal. if can, try to make a checking.
