I know this is going to sound strange but don't assume for the 2 lights you mentioned having the same lux readings of the spill, that therefore the total lumens for the one light must be underestimated. Low lumens yet high lux in the hotspot plus X spill versus another light, much more total lumens yet less lux in hot spot and the same value X for spill does not mean Light A undervalued their lumens. You don't know the total area of the cone of light for both of these lights taken at the same distance.
The pelican, putting out a much smaller cone of light and putting most of that energy into a tighter hot spot and then having some good number in the spill but that total area of spill is not nearly as large as the other lights in question when taken at the same distance is the key.
Taking a lux measurement of the hot spot and the spill does not add up to total lumens of a light. I have seen the Pelican 7060 and compared it to other lights I have and its got a nice hot spot but doesn't fill the room with light. In no way does it have the kind of lumens of the Fenix T1/Eagletacs, just a nice little hot spot due to the deep reflector, and what spill it has is okay, but the area is still smaller.
So this also means that the Pelican 8060 rated at 190 lumens is probably correct and not underestimated or understated by the vendor.
There are many threads that raise this same question. Many with the same mistake in the premise, that lights with brighter hot spots and equal or close spill numbers yet one with far less reported lumens must be undervalued. When you measure lux you are just taking a spot reading and don't see the whole value of light. That can only be done properly in an integration sphere that collects the whole volume of light. There is no magic to lower lumen lights having a bright hot spot with a deep reflector or tight focus optics but putting the energy into a smaller beam angle output. This has been answered time and time again.
My 260 (vendor rated) lumen Tiablo A10 has a much brighter hot spot than my 700 plus lumen Malkoff Triple drop. There is no question that the Malkoff Triple is 3 times brighter in total output, yet that A10 beam punches a hole in it like its not there, just in a much smaller spot (lesser square area or what I loosely say total volume). That doesn't mean Tiablo "underestimated" the lumen output. Its the apples and oranges argument yet again.
In short, the Pelican 8060 isn't going to magically have much higher than reported numbers and be more powerful than those other lights. If you like the beam pattern and the type of lighting/battery system it is buy it.
