Default phr actin weird!

ok....so heres what i got, a phr803 diode powered by a rkcstr microdrive adjustable driver set to 119ish mA

as first it all seemed great, but i started to notice a slight "flicker" in the brightness of the beam, then after a while it goes really dim (almost as if my batteries were dead)
then it will go to no visible light shining, but if i look in i can see this flickering that remind me alot of static electricity...

and if i leave it alone for a while it will go back to working......

think they is something wrong with the driver?
this is the first time i use an adjustable...i usually always use fixed drivers

if the current draw does not change when this happens
