This has no doubt been asked before but technology moves on, so what is the brightest readily available 5mm white LED when run at a modest current such as 10ma.
By "brightest" I refer to the total light output in lumens and not to a high candlepower rating that is achieved only over a narrow beam angle. Most relatively high power LEDs have a published output in lumens. But 5mm and other low power LEDS tend only to give a peak beam candlepower output.
10ma is about 30mw depending on the forward voltage, so at the now commonplace 100+ lumens per watt, several lumens should be available from a single LED driven at 10ma.
Colour temperature and colour rendering are relatively unimportant.
