#88750 - Contradictory requirement! Responding to: ???'s previous message |
Russell Bull said:
For outdoor signs he suggested using a temperature sensor to ensure the leds aren't run too bright when the sun is shining on the box heating it up. That's a bit of a blow! Surely, it is precisely when the sun is shining on the box that you need the LEDs at their brightest in order to be seen in the sunlight! Life is cruel! :-( |
