no these were cheap Chinese ebay specials no datasheet! maybe my memory of a very strange figure relates to it being very high not low. 110mA seems alot for a led
but at least i can go ahead and stick 10mA in and raise from there with no fear of burning it out
if i want to pwm the brightness tho i am going to have to use a transistor. thanks for the info. ebay is great price at times (these were mad cheap i got 10 units in a auction for £3 or 30p each
), ive had them about 9 months as i normally use the ones without back light as they are normally a bit cheaper and cost matters on my budget
