Did you just post a question without looking at the plethora of posts about lighting on just the first page?

Not to sound, OK, maybe I am, flippant, but I would take them if they are free, sell them on e-bay and use the proceeds to buy a great software program that allows you to search the Net for info. Oh, wait - there is Google... and a search function at the top of this page.

YMMV,
