I use sendspace.com & then pass around the link.

I'll see what I can do. From memory is a Regent 70W HPS Security light.
Home Depot carries them. Has a brown "cap" and faceted canopy around the
bulb, thus to spread the light without harsh shadows. Looking for the link
to this product, but can't find it yet. Will keep trying...

Thanks,


Dave
