EC11 or S10R?

Trying to decide between these two lights.

The S10R has 168 hr run time at 0.5 lumens while the EC11 is only 12 hours.

These close up a little at higher lumens. S10R is 3.5 hrs at 85 and the EC11 is 2.5 hrs at 70.
S10R is 0.8 hrs at 400 and the EC11 is 0.75 hrs at 300

My question is, why would the EC11 seem to be so inefficient at the lowest rating?

I like the mode spacing better with the EC11 but have questions about the efficiency of the light. 900 lumens are not necessary for me - 400 would be fine. However, the S10R is 0.5 / 5 / 85 / and 400. The EC11 is 1 / 70 / 160 / 300 / and 900. I think that the EC11 has, for me, a more desirable choice of levels.

Any thoughts on this?

Also, any opinions about general workmanship, reliability, customer satisfaction re: returns, repairs, etc.

Will probably buy from Going Gear and it seems that they will take care of processing any warranty returns.

Thanks for your thoughts on this.

The EC11 is on my list. I believe Going Gear is having a 20% off sale going on right now. Not sure how long it lasts.

Any thoughts about the 2 lights I mentioned? Nitecore efficiency? Choice of steps for each light? Warranty/service issues?

If I like a light, I buy it! I like lots of lumens. I don’t know anything about efficiency, nor the electronics end of it all. Both great companies, can’t go wrong. I have the S10, mine is modded, but it’s a great little offering. Seems to me you would happier with that one, it’s proven.
