hi, Crazylegs & Welcome
i converted my old up/over uva 18 tube to tl1o1 a few yrs ago now, i even put extra fans in
but got tolarant to it ! hoping 1day it will help again
have a read of the risks, how to check skin/moles etc
make sure your old sunbed tube end caps match with new tubes and best to stick to the same wattage
and your timer is spot on
there loads of info on here well worth a search
