What I’m “on about” is letting you know that the subject is not new. Using the search feature would help you find the threads where this has already been discussed. By reviving an older thread (by posting in it) you can bring up the opinions of others and help those new to the subject see all sides of the discussion.
Starting a new thread on an old topic is something that new members do all the time. For those of us who have the reponsibility of managing this site it becomes an indication that the newbie hasn’t done any reasearch, doesn’t want to, or is just lazy. Helping the new guys to learn about seraching makes everyone’s exeperience here richer and also helps consolidate topics into fewer threads, which is easier on everyone looking for a discussion on a particular topic.
I’d also suggest that you get the terminology straight. UV is ultraviolet, the kind of light that creates a tan. IR is infrared, the kind of light that produces heat. IV usually means intravenous and has nothing to do with light.
Here are a few threads easily found with the search button:
