YCCC TEK’s high-end electrodeless lamp YCCTEK EFL (inductive fluorescent lamp with built-in magnetic field) has its builb’s inner wall coated with trichromatic rare earth and professional three-wavelength phosphorous powder, added with nanoclass alumina material, to produce perfect values of color rendering and color tolerance, offering true color fidelity and brightness on the illuminated objects.
◎ The smaller the color deviation, the higher is the precision. (Standard deviation within 5)
▼ TCCTEK high-end electrodeless lamp has color tolerance within 2, an excellent value!
◎ The color rendering element Ra
The extent of color presence of the illuminated objects is called color rendering; in other words, it is the level of color fidelity. High color rendering performs a better color reproducibility, offering more nature-like color; while low color rendering shows poor reproducibility, thus making larger color deviation for eyes.
The following color rendering indexes cover 14 colors plus one more Asian women’s skin color added by China. They are marked as R1, R2, R3......R14, R15.
Ra stands for the average of the first 8 colors which are the ones most commonly seen.
R9 is a saturated red, R1 grayish red, R2 dark gray yellow, R3 saturated yellow-green, R4 medium yellow-green, R5 light blue green, R6 light blue, R7 lilac blue, R8 pink purple, R9 saturated red, R10 saturated yellow, R11 saturated green, R12 saturated blue, R13 Caucasian skin color (yellowish pink), and R14 leave green.
▼ YCCTEK high-end electrodeless lamps have all the excellent index values, especially the R9 value which is many times higher than some other types of lamps!
Some types of lamps have negative R9 values which will result in color distortion!
