Home exposure unit (screen printing) advice please?

Thank you @twinkleandgloomart and @AilsaArts for the info. I can imagine the sun technique could be quite unpredictable if there’s cloud coverage and time of day etc. I had read somewhere about using a halogen flood light were you remove the front glass in order to make it UV. I’m also working on a tight budget so slowly trying to build up my supplies bit by bit. The colour-corrected daylight bulb sound interesting and maybe one to look into. Thanks again for replying everyone.
