NettetThis instructable will guide how to use LEDs and how to make simple basic LED circuits, which current limiting resistor to use for operating LEDs with 3V, 6V, 9V & 12V. An … NettetCRI R9 is a very important metric because many light sources will be lacking in red content, but this fact will be hidden due to the averaging out of CRI calculations which do not include R9. As the chart below shows, an light source can actually perform quite well with the first 8 test color samples, scoring quite well for R1-R8.

NettetDepending on who you are speaking to, CRI can take on a very different meaning. Our recommendation is to be explicit when discussing these metrics with manufacturers and customers. When discussing general CRI, it is best to use the term "CRI (Ra)" or general CRI (R1-R8). When discussing extended CRI, use the term "CRI (e)", "Re" or extended … NettetAs tiras LED LED e neon são uma iluminação incrivelmente versátil, com uma grande variedade de usos que podem variar desde usos exclusivamente decorativos até mais profissionais. 216 016 336 - 935 235 785 .
