How low is the low on Sunwayman V10R?

[DimmerD]

I saw a video on Youtube from Goinggear that shows the Sunwayman V10R and the Ti version too. In the video the Ti version goes way lower than the aluminum version. He even says something about the Ti version going lower in the video. Both lights have identical specs 210 lumen down to 1, why would the low be different between them. The low on the aluminum version doesn't look like just 1 lumen either, it appears pretty dang bright. Heck if that's just 1 lumen I want to see the 210!

Funny you asked this question... I saw that video also, then look at the specs, and was wondering the same thing. I would want the same low low as the Ti version.

In my limited experience, having owned a Ti V10R in the past, and currently owning an Al. V10A and V10R, the lows on the three examples I've had have all been the same. If you're interested, see thread "Lowest low level comparitave beamshots... Here" comparing all my current low level lights for output. 🙂

The link to your beam shots is not working. If your saying the low on all 3 versions are the same, it seems very odd that goinggears video specifically shows both the Al and Ti version having two different lows... Marshall specifically points that out in his video. 😕

I just got a V10R Ti in the mail today from the new batch, and the low on it is much lower than on my V10R Al version I bought a while back.

Also on these models Low doesn't mean long run time.

My V10R is so low its not really usable. I'm talking it is more like a 'Find Me on the nighstand' mode. I've never seen a light go so low. That said, my son's light does not go as low as mine so it may be a glitch (feature??).

i just got my V10r Ti, and the low is quite low.

the lowest setting on my high CRI clicky is set at level 4. and its lower than that.

I am thinking there is a problem with the light shown in the video, it should go lower than that. AardvarkSagus recently posted a review of this particular light and I'll quote him here. "Rated at a mere 1 lumen, I have many suspicions that it is far lower than that"
Some others have said the low isn't really usable because it's so low, which makes me believe the light just isn't adjusted properly.
Anyway couldn't stand it and bit the bullet on a V10R Ti!!!

I too have ordered the TI version and I have a use for the low light setting.
Extra low light setting is perfect for looking at your watch at night when camping and in your sleeping bag
It doesn't light up much, but you really don't need much.
I have used other low light settings on my other LED's and few go down low enough

My V10r has a low of about 5 lumens. The light almost identical, in itensity, to the Nitecore EX11.2 at all levels, in a ceiling bounce.
From all I have read there seems to be a lot of variance, in the low, from one example to another. I think mine is typical and I do not need a lower low.

I have 2 of these right now but have had 5 over time between RMA's and no 2 had the exact same low. Of the 2 I have now one goes quite a bit lower, I think it may be a combination of board level component tolerance and emitter vf variance.

I can also tell you that there are different versions of the circuit board, at least between the Al and Ti lights I have.

Edit: OK, check this out. I transplanted the board from my Al light into my Ti light and now it goes lower than it did in the Al light.

I think the strength of the magnetic field penetrating through the Al body differs from that of the Ti body. Both metals are paramagnetic, but the susceptibilities are different: Al is +16.5 while Ti is about +150 (both in the same units). This could be affecting the signal the circuit board receives from the magnet inside the control ring since the field must pass through some of the control ring material.

Good catch.

Got the V10R Ti and man what a sweet light, goes really low. Feels very sturdy in the hand, bright when you need it and dim enough you can look directly at the business end on low.

I wish I had your light, but may soon be able to go as low. I'm talking to DaFab about doing some modification to my V10R Ti to give it a lower output and would love for it to go down as low as yours.

Doing comparisons with my Clicky which is at its lowest setting, they appear to have approximately the same level of total output. Don't know what lumen level would make me happy, but I do know that .08 is too high and my 007 and IFE1 are the only stock lights I have that will go low enough.

I have 2 of these right now but have had 5 over time between RMA's and no 2 had the exact same low. Of the 2 I have now one goes quite a bit lower, I think it may be a combination of board level component tolerance and emitter vf variance.

I wonder if it is tolerances of components as you suggest, tolerances of parts, as DaFab is investigating, or a combination of both?
Since changing components would probably make it impractical to mess with, I'm hoping that the mechanical mod will do the trick.

 

[Beamhead]

kaicho, I think it may be tolerance of machined parts and strength of the magnets used, perhaps there is variance in magnetic strength?
At any rate I like both of mine even though they are not exact clones.

Just got my V10R Ti today. The low is lower than anything I've seen so far for sure. Very nice little light. I haven't bought a non-US made light in awhile and this one does not disappoint.

All I can say is that I hope Tim is successful in getting the low even lower. I may to buy a spare too, just so I won't have to suffer from deprivation while it's getting modded...

My not so low one is still very low, any lower and it's pert near useless.😛
