What would be the advantages of choosing the s35 over a zebra light s51? From what i've read, twice lumens is not twice as bright and a zl will put out 200 lumens vs 380 lumens for s35 and runtimes both nearly the same on high?
Don't know why their runtimes specs are so low, but the 120 lumen spec seems bang on for my sample.Any idea why you got almost 6 hours on medium when all the published specs indicate 3.5 hours?
S35 Specs:
- Output (Lumens): Lo: 20, Med: 120, Hi: 380
- Run Time (Hours): Lo: 240, Med: 3.5, Hi: 1.5, Strobe: 3
XM-L doesn't seem to be well suited to lower voltage sources. And at lower drive currents, I've notice that current XM-Ls are no more efficient than XP-Gs (as expected, based on Cree efficiency specs).why didnt olight make a 1AA xml version?
they have a xml version for one cr123a.
an aa version limited to ~100 lumens would be great, compact but with long runtime.
Thanks for the numbers, and :welcome:I have been doing a simple runtime test on the S35 on the lowest mode.
The runtime was between 50 and 59 hours (it went out over night unfortunately )
The "hum" is believed to be induction whine, and is due to interference between elements on the circuit board. All lights can suffer from it, and its presentation is highly variable. When present, it usually has different "loudnesses" on different levels, or on different battery sources. It is impossible to predict whether a given light will have it, or to what degree. That said, some models do seem to suffer from it worse than other, likely due to the circuit components used (and their placement). I didn't notice any on either my S35 or S65 samples, but didn't specifically listen for it either (again, it may be there at a very low level that is hard to detect unless you put your ear right up to the light).I just got the S35 today and the first thing I noticed is that the light makes a humming sound when it's on. On low you can't hear it, but on medium it's there and on high it's even louder. It's not deafening or anything. You can only hear it when it's totally quiet BUT it is there. I've never had a flashlight that hummed when it was turned on.
It possibly could. Overall length is similar to a number of the shorter 1x18650 lights, but it is a little thicker. So if you were willing to EDC a 1x18650, this wouldn't be much worse. But personally, I try to keep my EDC down to the 1xAA size, which is a lot easier for belt carry.as a nb, i was wondering, would the 3aa be considered for an edc?

Many seem to associate it with PWM-based lights, but there seems to be no obvious connection in my testing - I have heard it just as often on current-controlled lights. If it is any consolation, you are less likely to hear it as you grow older (we loose our high-frequency hearing as we age - there is quite a difference in sensitivity between a 20-yr old and a 30-yr old, for ex.).
It is generally not considered a defect, but if it is loud enough to distract you when using the light, you may want to consider returning it.
