I am running a small head with 2 xpe leds and a seperate housing (plastic) for the bflex (running uib2) and the switch.
All works well on 350, 500 and 750 milliamps but when i switch to 1000 it cuts out completely after a couple of seconds.
I recall someone else on the forums having the same problem on high.
My problem is that my driver is far removed from leds and thus cannot measure the temp of the led housing. bflex is also a step down driver and does not require a heatsink thus it is just sitting in the housing.
I thought that when the voltage of the battery drops below medium and low the light will dim first before cutting out, although i am leaning towards the voltage dropping below the required voltage and the driver cuts out as the problem at the moment
I have to disconnect power to get the light on again.
I then set the power to 750mA and the light burns on without switching off.
Anyone have any thoughts about this.
This light will be a commuter light that will sit on the bar for heatsinking.
some photos with lenses in. still needs faceplate screwed on.
