I am looking for a 4 inch or bigger lense with a 2x or 2.5x like the one RedDevil said is needed for a big MH Bulb. So far i have no luck finding a "magnifier lens" online. Is a magnifier lense is the same as a double convex lense? I need it to be place in front of the bulb. Also, i used a tin foil tape as a reflector, is that good enought? Thank again guy.
Marklar from http://www.hommie.net/ uses an aspheric condenser lens with a focal length of about 35mm. This what you mean?
I really don't need it, all my light is not focused into one place, so i can't use it. I guess a magnifier needed to create an affect of a spot light because my light setup right now is like a flood light. Redevil has posted the schematic diagram in this forum:
