Fenix P1D CE - Q2 SE versus the original P1D CE - runtimes

[chevrofreak]

Fenix P1D CE - Q2 SE - High - Rayovac Rl123a: 1905 (est 136.07 lumens)
Fenix P1D CE - high - Energizer E2 CR123a: 1556 - (est 111.14 lumens)
24.72 lumens more output on High for an increase of about 22%

Fenix P1D CE - Q2 SE - Medium - Rayovac RL123a: 1046 (est 74.71 lumens)
Fenix P1D CE - medium - Energizer E2 CR123a: 833 - (est 59.5 lumens)
15.43 lumens more output on Medium for an increase of about 26%

Fenix P1D CE - Q2 SE - Low - Rayovac RL123a: 353 (est 25.21 lumens)
Fenix P1D CE - low - Energizer E2 CR123a: 236 - (est 16.86 lumens)
8.5 more lumens output on Low for an increase of about 50%

The old P1D CE may have had a higher Vf which caused the runtimes to be shorter on most modes. The Q2's have 4 bond wires which have led to a lower Vf as well as an increase in output. The lower Vf gives more runtime as well. I'm not sure why Low mode ran for a shorter length of time, perhaps the current level was increased? Either way, Low mode on this Q2 E is as bright as my old Fenix L1P, but it runs farrrrrrrrrrrrrr longer.

Quite the leap in technology.

Wow - excellent. Thanks for the info.

:thumbsup: as always, thanks Chevro!

I tested my new P2D-CE Q2 head on both both a P2D and L2D body, and saw a similar ~20% increase on Hi in my lightbox.

Imagine a Q5 in there ... oo: ... just waiting for the premium tint bins to become available.

And that is only the Q2's! Correct me if I'm wrong but aren't there also Q3, Q4, Q5 and R bins?

Nice!
