They are very white for 10,000k.
Its hard to compare different kelvin ratings as some 8000k kits are very blue and some 10,000k kits look the same as some 6,000k kits out there.
A quick search on google you will be able to compare different branded kits and you will see there is a big difference in the colour, of the same kelvin rating.
I think ill get the 6,000k off Slide. Nice tutorial BTW but i dont think cutting the wires was needed.I have installed a few kits with no cutting what so ever.
