Re: What's the REAL story with LD11's and heat?

["geraintuk" <geraintwilliams_uk@xxxxxxx>]

As per Keith's points.

I did mine as two modules side by side, then a gap etc.

There are pics of my consumer units in the PHOTOS section of the=20
group under "Geraint's Node 0"

You can see how it's done. At =A335 a pop I don't want to have many=20
LD11's etc go faulty on me.

Geraint.
