I am new to LED scene, last time it was luxeons and 1-3 watt discussions, which leaves me somewhat disarmed for the way in which LEDS are rated these days- and some what confused about this.
I have been looking at MFRS specs for (mostly) 5050 chips and either I am not getting or the information sometimes is absent? - As I understand the current ~300-3000Ma is a good indication of the capacity for brightness of an LED whilst Lumens is the actual output.
Hows does one determine the brightness of a LED from MFRS spec sheets - i have seen lm per watt - what do I look for here (bit lost) max output, max watt ????
also I am looking to have a few 5050's on a board. - mixing types can cause issues as the power supply would be the same, just the 5050 led would change ...risk?
