Medium White Light Quality - Yellow Shift Solved
Good prior comment on color uniformity at the far end. I ran a test, powering the strip at one end with 12.0VDC and here is what we found:
Strip consumed 0.91 amps. Uniformity at the far end was more yellow than at the near end.
As a test, I split the strip into 10 sections 19.5 long at the solder bridges. Putting these 10 strips in parallel resulted in 1.55 amps of current draw and no uniformity problem. The strips were adhered to a 0.100 x 3 x 20 piece of aluminum.
I did have one segment of 3 leds that failed after about 30 seconds of power-up, and the last led was curled too tightly on the real creating a kink in the silicone elastomer causing it not to stick down well. Some clear RTV should solve this.
Later I ran it up to 12.6VDC and it consumed 1.84 amps. Running it for a few hours more yielded no additional failures in the LEDs. Be aware, the aluminum plate heats up, so make sure to have some way to dissipate the heat. After two hours of sitting on a counter no air circulation from the back, it was very warm to touch.
The LEDs are powered in groups of 3, so a lost of one segment is only about 1% of the light output.
Net: Powering up the strip from both ends or using it as shorter segments works pretty good. Running several strips in parallel minimizes the impact of a loss of a section of LEDs.

The first few feet of the strip has more of a yellow color then it changes to white. One segment of LEDs or 3 lights does not work.
