Also, does it get dimmer?
Looking at lightreview, the LF5XT goes both much higher and much lower then the 120P, and the LF5XT also has better runtime.From the info so far you should expect higher output on high, and not as low on low. Little good and bad there...
Thats because in that review, the lowest tested output level on the 120P was level 18(30 lumens), it goes all the way down to level 1(.08 lumens).Looking at lightreview, the LF5XT goes both much higher and much lower then the 120P, and the LF5XT also has better runtime.
