OK, so I built a homemade light box and measured all my lights. I plotted this on a graph against their manufacturer rated outputs and I came up with a reasonably straight line. All the 240 lumen lights read about 70 ( units ) on the meter, the 120l read about 35, the 80l read around 23 etc.. All multiples of about 3.4. This line is nice and consistent from 70 lumens up to 600. Using this I can extrapolate the 'rated' lumens for lights I don't have a manufacturer rating for.
I put a 90% charged 10440 into all three of my Preons and got readings of around 85. That's over 280 lumens !!! Outperformed my RRT-0 on a CR123R. Not bad for something the size of my middle finger.
For 10440 fans, some of the other readings I got were.
Liteflux LF2XT R2 130 l ( But much longer runtime.)
Fenix LD01 SS 250 l
Maratac AAA 220 l
And yes, Four Sevens advise against using 10440 cells in their lights as do Maratac, Fenix, etc… Only the Liteflux LF2XT is designed for it. Lets not start down that road as it's been covered a hundred times over. I just wanted to post my readings.
