I'm curious for more details about this. What exactly did you change about the behavior? Are there instructions on the web?
It requires getting to the driver board and using a pencil to wipe graphite across the capacitor that controls the duration of the memory circuit. When you find the right one and get the right amount it will reduce the time it remembers the current mode. I used to have a page to post a link search "next mode memory LED" I think will do it.
I've been hearing a lot just recently about people trash talking zoomies, but not sure why. I had one stand up to long term construction use in a pocket or even loose in a toolbelt with other junk. Probably took a few drops. These ones I have like the photo seem durable enough that I can't really imagine them breaking without some real significant accident or being dropped in the mud or something. And they are only about $6-8.
The next mode memory is probably an issue until you defeat it the light is irritating. The lights sometimes also can have poor quality control and exhibit electrical problems and the sliding action can be too stiff or too loose. I have one that if I bump the head it changes modes on me. They can break as the construction is flimsier than better made lights too. The problem is these lights are not made in the same factory all the time but different factories and quality can vary hugely you may get a really good one, or a mediocre one.
I think they are pretty amazing lights for the price. Quite happy with them. The only reason I even ask about another is seeking an even better brighter one since I think led technology has evolved in the past 6-10 years but these flashlights have stayed the same. But maybe I'm just oblivious to how much better a higher end one might be, having never seen it.
I do see it seems most $30 range lights are now using the lh351d emitter. Not sure exactly how it compares to the XML-T6 since I couldn't find a direct comparison, but I'm guessing its a lot brighter and higher CRI. I might pick one up to see how they compare. Although so many have unnecessary stuff like a usb port and charge circuitry making it longer etc. Really wish I could find a super compact zoom one like the ones I have, just with a newer/better emitter, and without the mode cycling through unnecessary modes.
[/quote]The "XML-T6" on these is but a ruse to make you think there are Cree brand LEDs in them when in fact they are chinese clone LEDs. For the price they are adequate but not the quality nor the efficiency of an actual Cree LED. I'm not sure if they can even be driven as hard as a Cree LED either but then there is the driver circuits on these lights typically 3 modes H/L/Strobe and compared to the $30 lights it is more like medium/medium low. The tint/cri of these lights is inconsistent and all over the place. I'm guessing that on a fresh battery you may get 300 lumens but likely more closer to 200 lumens IMO but I'm not that great at estimating things others may have a better eye for that.
There are othe lights with 5 modes and no next mode memory but they have their annoying issue of excessive strobe modes often a strobe AND SOS mode and if you don't use them you have to cycle through them to get back to High again.
IMO if you get a decent one of these lights that take 18650s or AAs for around $5 they are nice but when they start creeping up towards $10 then it gets more of a gamble as you could buy 2 of them to get one that you like and that pushes you towards the price of a higher quality light with a nicer UI and brighter and dimmer modes and often hidden strobe modes.
My one issue with zoomies that goes back to their predecessors that were the "moon ball" type magnifying glass output is when zoomed out you have a bright ball of light that can shut down your eyes and anything in the ball area you can see but there essentially no spill light and you can't see beyond the ball so you are constantly having to move the ball around to see things while a reflectored or well made optic light has spill and you can see at the edges without moving the light. In other words if you are walking in confined areas you can see things that would be in your peripheral vision areas with a reflectored light but not necessarily with a zoomie. The hot spot when zoomed out also exhibits little spill light. Basically in order to concentrate the light you lose all spill and can basically only see within the focused light area everything outside of it is dark as your eyes are oversaturated.
Once you get a decent higher output reflectored light with a high power quality emitter you will desire its beam to a zoomie more often.
BTW most $30 lights are using CREE XML, and XPL emitters but there is a wide variety of them often using Nichia and other emitters I've lost count of the half dozen or so emitters used now but these better LEDs are a lot more consistent in tint and output vs the clone emitters that you can have one blue another pink and then green it is a crap shoot on them and if you are doing something that color rendition is an issue you may have to get a half dozen of them to find the right tint to use often different color shells from different vendors as batches of them probably use the same LED batches.
I was happy with mine after I got the next mode situation worked out, but now I have high power cree multimode lights in the $30 range I now consider them more disposable and grab my 1200 lumen Sofirn or my 2 18650 headlamps that do 900 lumens on turbo and have 5 lumen low modes and hidden strobe modes. There is nothing as awesome as a 1000 lumen LED light with a nice reflector the first time you go into Turbo on a dark night and a wide area of your yard lights up almost as bright as daylight the zoomies pale in comparison and quality output.
Well spaced modes also are wonderful as with the cheap chinese lights you get something like 100/50/25 or 100/50 percent modes and the 30 dollar range of lights you get something like 0.1/0.5//15/50/100% modes and the super low modes on some lights are "hidden" and Turbo modes on some are hidden too so you get outputs of 5 lumens/125lumens/500 lumens and it cycles from L to H instead of H to L like most of the cheap lights. Having it start from Low is a huge advantage because you don't shut down your eyes nor wake up people around you that may be sleeping plus the lower output conserves power you can run at 5 lumens on more efficient emitters a lot longer than low on a zoomie perhaps 5-10 times longer.
