Regarding the blue or “cold” color of LED lights:
I spent the better part of a year searching & testing lights for a
new kiosk I am building, & ordered / looked at LEDs from a half dozen
different companies.
I ended up purchasing LEDs from a lighting company in Miami, FL
[Future Designs (305) 871-8774 ]. Their LEDs are available in two
color temperatures–4100K and 5500K. I think the 5500K is too blue,
but the 4100K looks great & is very white.
At $175 per linear foot it wasn’t cheap, but I’m hoping it’ll pay
for itself in the long run.
