Render this: L.E.D lighting

Cool reference photo. It would be even cooler to have a LED model like this one (wink, wink).

I had a bunch of LED's next to me when I was trying this out earlier. Kept hot-wiring them to a battery until they got hot. -
Closer observation of LEDs reveals that only a part of the plastic is actually lit, so here's an update.
In reality, the lit part starts with a conical shape; I'll try that tomorrow. -
Miguel...the new one looks better, IMO. I think the "cone of shame" added a lot of realism. Care to post the model?
Here's an attempt with a green LED. Not really happy with it. I used a tiny Vray sphere lighting in each of the LED's. I tried an emitter plane, but it looks crappy. Used a soft water SSS material for the bulb casing. Took forever to render the 202 lights!

OMG!! A Point-Light for any led, it's a rendering nightmare...

Not if it's just a handful of LED for close ups.

i think majid's and earthmover's LEDS are most convincing. majid captured that falloff that you get with LEDS...they act like mini spotlights (well the one on my keyring does anyway). So I imagine loading an IES will work well.
-
OK, this time I modeled a tiny metalic "cone of shame" (he he he) around an even tinier emitter, to better simulate the light source in a LED.
I'm not sure if I like this image better than the previous one:
Different exposure:
EDIT: Added the model with the cone.

Here is mine:
Transparent materials - real glass and that's the only correct material here
-
this is my try.sketchup + KT and also the result is a photoshop combination.
Also you may try it(unzip and load the KT file, attached)
-
First try
(I know I am a little slower at getting this done than some of you. Actually we found a bug where we were processing curved light emitters too slowly, so this helped fix up the software as well)

Dang. Majid, you beat me to it. I should've checked this thread before building my LED. Oh well, here it is anyway. Feel free to do what you will with it. It's a bit overboard detail-wise, I even threw in a few air inclusions.
I based it on this picture:

A quick try (10 minutes) with Vray for SU first version...

Hi all,
my first post on this forum today!
This is my render of the L.E.D. Lighting:
-
Ok mate, I tried to keep and respect your level of details, hope you like it
(distort correction and a bit of bluring , by PS )

-
Nice job. I used KT as well, gotta work on my materials. Only thing about KT is that it doesn't do volumetric light beams, so I got the same result as you did in your red LEDs; a bright surface light, but nothing "inside" the LED.

-
it does volometric lighting also, but I didn't used
-
Some nice attempts of rendering LED strip but you wanna try chip leds as opposed to those 5mm. This would be a lot easier..
