Today my red 4″ cathod lights turned up, I brought these to replace my white 12″ ones as I thought they where too bright.
So I switched them over so I now have some really nice red lights on my desk allowing me to see the keys I press really easily and the best thing about it is when you want to read a book its brilliant if you have a white light and want to see what its light just buy some thin red paper a cheap way to check it out 
I really couldn’t go back to my white lights after this but another plus side is having desk lights allows you to save a lot of power my room lights are 4 x 50w now these under the desk are just running of my computers molex connectors.
So what happened to my 12″ ones?
simple answer is i put them in my case, I do a lot of work inside my case as I’m studying something to do with fixing computers, so this has been a massive help as the brightness allows me to see anything inside the case 
, but only when its on which isn’t a problem very low voltage goes through the computer.
Don’t you think this is a good idea to save some money on your energy bill as you wont be using your room lights as much too see the keyboard so check out your local shops these cost me around £2-4 from ebuyer.com
