I've done a search in the forum but can't find the good threads with pictures. I remember i saw some pictures with flat top leds but the search engine can't find them for me
Thanks bcbox! The left led looks somehow better. I've ordered blue flat top leds which i found only in water clear lens color. My wish was blue diffused flat top leds or with diffused lens color like the left one on the pic, i think these do not exist with blue light. If i'll use flat leds they must be totally flush with the panel, otherwise i solder my standart blue diffused round leds.
Thanks for the hint with the standoffs
This is the flat led i've ordered. I hope they look good in real ...maybe i use sandpaper to give them a diffused look like the led on your pic bcbox
