I don't think strobe should be implemented in a spot light so to me the UI is perfect.
There was a reason for the light no longer being able to run a single 18650 like the V1. I believe the driver puts out more amperage to led, because of the different driver, more input voltage is needed. Too bad it is too much draw for 2 cr123's on high.
Overall it is a great light. Just think of the single tube as a way to run the light on low with cr123's in a compact format.

Also due to the change in drivers, the operating voltage has been bumped up to accept the 4xcr123 format as well.

I love the UI on the Version 2, I can use the switch for fast flashes of light without any risk of changing levels and I have no use for a fast strobe mode.
If I really want to run it in a short configuration I can alwaus load it with 2x16340 IMR cells, but the light uses way to much current for any real use in the short configuration. It is not even a good idea to CR123, the light is definitely designed for 2x18650 cells.
I would have lowed that the low was a bit lower, but that is a very minor quibble.

I have the rrt-3 with the 3 18650 mag and it makes the light too bulky to me. In all reality I use my catapult v2 a lot more than the rrt-3. It fits my hand well and I'm glad they got rid of the useless strobe. I do wish they made it so 1 18650 would work in it though.

I don't know if there was a technical reason to cut out 1x18650 support, does seem a strange decision if not. As far as the UI goes though, a strobe is supposedly a 'tactical' feature, and this a search/spot light. So for someone who actually uses it in a work environment for that purpose, strobe would just get in the way of what you want it to do, I.e. light that field up over there, now.

Once you look at voltage sag under the high current, and throw in some voltage loss in the circuit (especially at high amperage) you are best case getting limited regulated runtime. Worst case with some cells you aren't able to get the full 3A current unless the circuit boosts. I'm sure there would be a lot of unhappy people here over not pushing the spec'd current.
Of course they could use a boost or buck/boost circuit. Building the light around a buck boost would not only be less efficient, it generally comes at the cost of not supporting 2xLi-ion voltages. Throw in the fact that boosting takes you to or above the limit for some lower capacity 18650's sustained max current and a single 18650 just doesn't seem like a wise design choice for this light.

Thanks for this post. Makes perfect sense to me now :twothumbs

DO two IMR16340's work on high?

This might work, the light has a maximum current draw around 3.5 ampere and IMR 16340 can supply 4 A. But you will get a short runtime.

Most of the time yes, but when the batteries are just about empty the current draw will increase!
