What size led is brighter, 3mm or 5mm?

Question

I noticed that oznium.com charges more for 3mm prewired LED's than 5mm LED's so I was wondering if the 3's are more powerful? Thanks.

Answer 1

LED size has little to do with intensity but normally the biggest would be brighter with all else being equal - but also the biggest would be more expensive so something is missing here

intensity is determined by the type of lens - voltage - efficiency

WENT TO THE SITE they say nothing about a difference in brightness ( except that the 4 - chip is brighter than both ) seems to be manufacturing cost

Answer 2

3mm way brighter
