thanks, yeah it's a mk 2, i was looking at e-bay but i'm a little weary about buting anything electrical off of there, i wouldn't mind paying a little more for the peace of mind, i'll ring around a few websites. When it come to the Kelvin rating, i was looking at the 8-10000k bulbs, i don't want anything too blue but also don't want to be stopped every five minutes with the book being preached to me, i just don't want them to look as cheap as i've seen some, i do have the quad LED 501's in there as well witch do look nice, cheers.
