Default From Orange to Blue

Lately, it seems that Blue LED's are all the rage. Here's a way to add them to a classic kit. I've made a small assembly of blue led's that fits in the space of a neon lamp. With a change in the dropping resistor(s), you can use it anywhere you would have used a neon lamp...

I haven't gone into production yet, but I figured people might like to see it.

Now all you've gotta do is stock up on neons for when people get bored with the blue and want to go back to the "classic" look.

Will you offer them in different colours like green or in a low brightness level? Just curious as I find green less retina searing in the dark.

What about one like this? You can have your choice of 3 colors or blend them in different intensities.

Actually I plan to use one of these in the next project to indicate...blue for stand-by, green for active, and momentarily switching to red for clipping indication; all in one indication.

How much more current does it draw compared to the 0.3ma for a NE2 neon lamp?
How hot does the dropping resistor get when you operate it from 120V or 240V (overseas) AC power?

RJM...

The DIYAudio forum is better than google! I had read that blue neon lamps were available, but when I googled them, never found a source. That's why I made this LED assembly. Right now, I'm running about 5 mA through it...It's probably too bright...I might eventually settle on 2.5 mA...but then, if this blue neon lamp looks good...maybe that's the way to go!

Thanks for the link!

Dan
