Hi Roger999
Thank you for replying to my post. I've been reading some of the post related to Full spectrum light and its all very confusing. My plan is simply to project a small intense light soarse through a prism and make a rainbow. Do you have any ideas on what type of flash light or light soarse I can use to do it? It seems that if anyone could help me its someone on this web page. It means alot to me to find the answers to my questions. Thank you for any help and ideas you can give me. Don
