RE: Thoughts on Very high intensity blue leds.

["SPEEDER ELECTRONICS" <speeder01@xxxxxxxxxxx>]

He sold them to one of the London galleries. He did the elctronics with
555s!!! I never saw them in situ.

I can't remember if he had some 'white' leds as well in there.

We only got involved on the brackets (very Hi-Tech).

Ick, things look aweful under "white" that comes from the mixing
of RGB
led's, I
would have thought an art place would be concious of this.
