Pre-poll: Help me make a list of mode schemes

My dreamlight has a set of 3 programmable modes for normal use and two hidden blinking modes: the alpin distress signal and a slow beacon. The brightness of the blinking modes and the frequency of the beacon is also adjustable. Turning the head or the tailcap activates a separate red LED w/o any "click"-noise.

Maybe impossible to achieve but imho ideal for any task outdoors may it be in the mountains, the sea, in the woods or in a cave.

I can see that people do have a use for really low modes, but with the light pollution around here, spotting the huge black dog in the park at night is an 50 lumen or more job. And that's when she is close to me.

I would be interested in a really long-running 10-20 lumen light that will run forever on an alkaline AAA - preferably smaller than a Fenix E01. Probably a pure flood light that could live on my keychain. Something like the Fenix E05 but smaller and half the price - or less.

Single mode for that would be fine. I would not mind a moonlight mode for that but I'd never use it. That would be perfect for searching under my desk in a very brightly lit office.

The last time I felt I needed a really low level light was while walking through bandit-infested country in 1985 in a very remote part of Africa. It was so dark that night that the glow-worms (Think really dim green LED - that is exactly what they look like) were almost dazzling. 10 lumens would have been blinding. I walked the 10 miles from the bus stop to where I was going mostly by touch. The reason I was walking was that bandits had already stolen just about everything I owned.

Very interesting idea! This is surely feasible right now, with the circuit that Mrlite already uses.

Any more non-programmable mode schemes you'd like to see?

Something like low, med, max with a second set of modes that have ultra-low and whatever else. for the ultra-low fans this might not be ideal so I'd accept ultra-low, med, max with a second set of modes that do whatever...

I still need to read up on the Mrlite 2-stage 9-mode scheme. I think some of you tried to explain it with the KC-05 reviews, but I never could wrap my mind around it. And the part of Mrlite's owner's manual that explains the mode operation makes operating a nuclear power plant look like child's play by comparison.

Till you get the knack of it (Which i do not always do) they are 4 mode lights that have 5 more inaccessible modes.

Its kind of odd that MrLite uses that 2-stage circuit and then the modes for each stage are so similar. Its like the circuit was made to have regular modes on 1 level and then the auxiliary odd modes on the 2nd. I could go for a silver version of the LT2 (I think that's the AA one) and then have the primary level be 6 lumen<50 lumen<max, and then have the 2nd auxiliary level of being moonlight<beacon<strobe or whatever flashy modes people like. Wrap that up for under $25 and you have a winner and Fran gets his XP-G. (You could actually do up the whole LT series like this for people who want alternate battery types.)

As I mentioned in another thread, a few simple pwm modes with exponentially increasing brightness/pulse density (the admin's favorite scheme ;)) would work really well with mode memory because it's essentially a programmable light.

"Programmable" lights are essentially this in concept, except they store the pulse width/density variable in much finer resolution and perhaps can't use a strict state machine internally to keep track of modes. But's all down to programming the exact same mcu differently, really, nothing physical/magical about it unless you want a special design and that costs $.

I have a fenix E0. It's almost what you're looking for. 20hr claimed runtime but only 5.5 lumens. It uses a 5mm nichia and puts out really blue and dim light. It's the smallest light fenix ever made. Smaller than any other 1aaa light i've ever seen. Won it in one of the fenix survey giveaways. I would have never purchased such a dim light.

I had this exact same idea floating around. That would be extremely convenient :)

Also for the record, I really love the Akoray k-106 styling as lots of ppl have mentioned! Still need to add one to the collection. I bought one for a friend and honestly its a piece of garbage so a quality light in that body would be great!

I have both an E0 and an E01. I agree the E0 is too dim and the beam colour of the Nichia GS in the E01 is not pretty. There is clearly a market for such a light though, a lot of people seem interested in the E05 recently announced. I'm not interested in the Fenix price for that light though.

The E05 was in the back of my mind as I wrote that.

I think the mode levels should depend on battery type. I prefer the mode sequence of Lo-Mid-Hi-Max. I strongly prefer a properly working memory. It shouldn't be that hard to make. Skyray S-A1 does it correctly. If mode memory cannot be had, then Mid-Hi-Max-Lo is more practical. If a mode ring can be implemented at a reasonable cost and without adding too much size, then that would be perfect.

For single AA-size flashlight, I think the Lo-Mid-Hi levels used by ITP A3 is perfect. Just add a reasonable max level to it. The Lo, Mid and Hi levels should be the same for both NIMH and 14500 batteries. The Max can be different for each battery type, but should be reasonable for the battery type. Probably the Max level should give about 30 minutes runtime for both NIMH and 14500 batteries.

For larger than single AA flashlight, I would expect it to be brighter. Maybe the Lo-Mid-Hi levels should be increased by 50% from the single AA size levels. The Max should give about 1 to 2 hours runtime.

Please use the latest LED (XP-G) in neutral color.

BTW great website! I also ordered a silver Mr Lite BLF AA-Y4E. Many thanks to Mr. Admin's effort.

@sb56637 Can you "reveal" what is the next light you are going to "customize"..... to have an idea....

Aloha and welcome to BLF lightguy! Smile

The most user-friendly flashlight I own is the Eagletac P20A2 Mk II.

This is because only 2 modes (max, medium) are accessible up-front where you need them.

One has to turn the bezel to change modes.The other modes (very low, strobe, beacon and SOS) are "hidden" but readily accessible when you need them. This is done by quickly (within 1 sec.) tightening/loosening the bezel, the number of times depending on which mode is wanted.

I think most of the time only 2 or 3 light levels are needed and strobe and the other stuff only occasionally (unless for specific uses, like bicycling).

Of course it's nice to want a lot of things. The bottom line is at what price point can these sort of features be incorporated into the design of a flashlight?

Don, with that want, I'm suprised you haven't looked at the Nextorch K1 yet. About as small as you can get in AAA format.

Probably because I wasn't aware of it. thanks for the tip.

Is there another brand of light that looks very similar? I'm sure I've seen one that looked like it before, but can't place it.

The one problem, it looks like, is that the K1 is more throwy than floody. I haven't seen it labeled as any other brand, though I understand that Heinnie in the Uk does sell it, albeit at a much higher price. I don't actually own one yet, but it has been on my list for a look for quite some time and lightake just started carrying it a couple of weeks ago. I may still order it at goinggear instead though, with it being a US dealer and getting the light much quicker and all.

Welcome lightguy! Good to have you here.

Please do join in. Everyone's opinion is important so please do feel free to join in.

Thanks for the compliment lightguy! And welcome to BLF, please enjoy your time here.
