Here are some more comparison pics for those curious about the Lux V3 vs V4 LED angel eyes... I ended up liking 6300K the best. I put the module in such a way that its actually really easy for me to just flip the lid open and change the color temp. I had a lot easier time installing the V4s for some reason, I'm either getting better at it or it really is easier to install than the V3s.

Lux V3 on left, Lux V4 on right (5000K - hard to see in this pic, but this looks way whiter than the V3, no blue at all)
