My sku 16092 MTE has ran 6X now continuously in excess of 75 mins on high (4 of these were 83-86 mins, also on high). It was probably getting dimmer towards the end but I didn't notice - didn't seem to dim much, really.

Used trustfire 2500 mah, which are probably really only 2000-2200mah.

The DX description of "2800mA current output regulated" is clearly not true. Probably closer to an average 1600ma based on these 6 rides.

I think I'll get a 13060 and use the 3hz mode with a red lens for a tailight. The color produced is actually an orange shade. In side-by-side test using 16092 on fast stobe. it completely overwhelms the 3 PB Super Flashes I've been using. Can hardly see the 3xPBSF looking at them next to the 16092.
