Beamshots of Penlights, September 2010
Some other comparisons with penlights:
Beamshot AAA lights, June 2010 this comparison includes 4 penlights and 4 1xAAA lights, one of the penlights has a build in laser.
Beamshots of AAA flashlights, January 2010 this comparison includes 6 penlights and 7 1xAAA lights.
In this comparison I have included all the common penlights, they are (Same sequence as picture): 4Sevens Preon II cool/neutral/warm, Icon Solo, Fenix LD05, EagleTac P20a2, Streamlight Stylus Pro
As can be seen I have included 3 versions of the Preon II with different emitters. The cool version is from the first production run and has a slightly different build, than the newer Preons.
All measurements and beamshots are done with freshly charged eneloops.
The brightness of the lights falls in two different categories, the high brightness ones and the low brightness ones (Icon and Streamlight). The Streamlight is a rather old light and this may be the reason for the low brightness, but the Icon is a new light, done by a very experienced designed, i.e. it is definitely by design.
With the Preons it can be seen that warmer light color has lower brightness (this is related to the construction of the led).
Including all brightness settings of the lights, shows that all the 3 levels lights are rather close in level selection and that Solo can best be described as medium and low, the EagleTac is more like medium and high.
Measuring the lux from 1 meters distance, gives an idea about throw. The Fenix and EagleTac are best at throwing. The Streamlight and Icon might have a good focus, but with the low output, they cannot match the other lights in throw.
Putting the lights on a scale, shows that the Icon is rather heavy, this is not very surprising with the "fat" design, made in aluminium. The Fenix is just as heavy, this might be due to the stainless steel front and tail?
