    JetBeam Jet-III M (Military) Review - RUNTIMES, BEAMSHOTS, DETAILED PICS and more!

    Vf is the forward voltage of the LED, that is the voltage needed for a certain current through the LED. So the lower Vf of the Q3 means, for example, that ist needs let's say 3.5V for a current of 700mA whereas the Q5 needs e.g. 3.7V for that. Don't take these numbers for granted, it's just...

    Fenix P3D-RB100 Rebel Comparison Review

    Well...with the li-io the current is much smaller than with the original L2D setup (only 0.41A compared to about 1.1 Amp). So the electric power dissipated in the spring is much lower (P=R*i²). The higher the voltage and lower the current (at same power output) the lower the losses in the...

    Dereelight CL1H V3.0 DI WH R2

    I got my DI Q5 dropin two days ago. It definitely emitts some noise on the lower modes, but that is not really annoying. What I don't like so much, even if it is not too bad, is the PWM. Moving my hand in front of the light on the lower modes I can clearly perceive the typical strobo effect of...

    DBS V2 DI Cree XR-E WH R2

    Yes, you are absolutely right. Well...I know how PWM works...but didn't contemplate enough about it:o

    DBS V2 DI Cree XR-E WH R2

    Waht I meant was...did you measure the duty cycle of the current or the output. If the letter..... I take everything back :wave:

    DBS V2 DI Cree XR-E WH R2

    Did you directly measure the LED current? If so the spec saying 50% isn't thaaat wrong as it is refering to the output. Looking at the relative Intensity vs. current chart of the XRE and and assuming the LED is driven at about 1A at 100% output you get a relative intensity of about 220%. At...

    OLIGHT T15 Q5

    The current version won't be able to adjust brightness when using 14500 LiIo rechargables...according to Olight. The upgraded version of the T15 sis supposed to be released at the end of the year.

    Fenix P3D Premium 100 Rebel

    P2D head to P3D body: NO WAY, the voltage would kill the circuit of the P2D head (at least it would override the LED AND the circuit! The other way round may work, but the P3D circuit is made for the high voltage of 2 CR123. I am not sure, how it will behave with less than 3V.

    Fenix P2Dce Special Edition Q2 Comparison Review

    Hello, do you have any beamshots comparing low and medium mode of the standard L2D versus the Q2. I red somwhere that the two modes are hardly dustinguishable in the Q2 becuase of its brightness. Does your light have the same characteristic? Best regards Ingo
