anyone used flat top leds ?
At the moment i'm thinking about to solder flat top leds instead the standard diffused round ones, does this look better and how do they fit in the panel? Do i need the ledstandoffs for the flat leds?

Re: anyone used flat top leds ?
I've seen a number of threads around here where people have done this, so no reason it wouldn't work.

it looks pretty cool, and yeah you need standoffskatarakt wrote:At the moment i'm thinking about to solder flat top leds instead the standard diffused round ones, does this look better and how do they fit in the panel? Do i need the ledstandoffs for the flat leds?
if i recall, the kits that offered flat LEDs had different standoffs (they were shorter??)

Re: anyone used flat top leds ?
I can check for you on the height when I get a chance. It depends on whether you want them totally flush or sticking out a little.
I think I have some pictures somewhere. I actually prefer them sticking out a bit. I've got several hundred of the same flat-top ones
Limor was selling in the past. They look great, the lens is a diffuse white-ish color and and LED emits a very red color (hard to explain
but they look better than the other diffuse red flat-tops I tried).

Re: anyone used flat top leds ?
The box below has flat top LED's that stick out a bit (the blue step LED's are round). Click on the pic for hi-res. If you do a search I remember there's some pictures from a couple years ago from a few that put their LED's perfectly flat.
This pic below is a Bright LED BL-C4237-T on the left and a Kingbright WP483IDT on the right.
The height is 0.378". To make them fush the closest standoff would be 0.16". I think most of the guys who use these set the heights individually either with or without standoffs.

Re: anyone used flat top leds ?
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

Re: anyone used flat top leds ?
...here's the thread I was thinking about...
http://www.ladyada.net/forums/viewtopic.php?t=376
btw, those leds look shorter so standoffs may need to be longer. If you can get the datasheet for them you can do the math by comparing the led height to the PCB standoff height used in the x0xb0x.
LED Standoff height = PCB Standoff Height + Panel Thickness - LED height
so basically the standoff height is 0.531" - LED Height

Re: anyone used flat top leds ?
Yep, that's exactly the thread i was looking for thx
I'll measure everything exactly and order the right standoffs for them if i'll use these flat ones. The flat leds from this thread are excellent! Problem is i need them in all three colors: blue, green and red. This year i'll try soldering 3 x0xes, first one with blue leds, second green and third red ...first one is finished soon, i want to go as 100% as i can...sometimes i feel like a perfectionist
