Experimenting with LED striplights

I started using 4100k t-8 bulbs, horrible CRI....Ordered LED striplights, suppossed to be 4000K, not even close - that upper light blue and lower dark blue IS the SAME color paint! There are actually three colors of light used in this pic - The upper left is GE Sunshine 5000K high CRI bulbs, the lower is the LED... and past the boxcar and drawings is the 4100K lighting. I will slowly switch to 5000K bulbs, and order some LED's that are 5000K. If they don't work, I'll use GE Sunshine CFL's in some areas.
