Nice refurb. I noticed the shorting of the screws before I went to the second page and saw you solved that problem. I'm getting into the new high power LED stuff myself and found an easy solution to the washer for mounting screw problem. Use rubber hose and cut into 1/8" lengths with a pair of wire cutters. Very fast to make lots of rubber (non-conductive) washers. Use 1/8" diameter hose (or whatever size screws you are using, although all star-based LED's I have seen you must use #4 or smaller screws) Viton (400 degrees F max) or Norprene (200 degrees F max) hose.
keep up the good work.

@Giorgos Lazaridis You are right. I guess I was too tired that time. However, congratulations for the lamp.

@Metalshrine 1/sqr2 = 0.707 so it is the same

Man, I think you have a mistake at the beginning. Vrms*sqr2=Vpp. At least this is the way I know it.
