Ummm...not so exited about moon mode with a floody. 2lm flood seems about as useful as 0.2lm with a reflector. Yes, I'm generalizing but I think there is such a thing as too low.
2lm can actually still be usable.
My first proper homebuilt caving lights had spot and flood LEDs, and used early ~20lm/W luxeons at 1/0.3/0.08W per LED, so the low power was about 2 lumens.
Without having anyone else around to spoil my night vision, the naked flood LED on low was perfectly adequate for moving around at normal pace in narrow-ish walking passages and doing ropework, in caves of fairly white rock.
If it wasn't for the control complexity involved that probably only I would end up using, I'd be tempted to stick an ultralow power mode in the next iteration of lights, now LED efficiencies are >5x higher than the first generation.
In fact, having thought about it, I might do that anyway, just as a one-off for me.
