Which is better, 99%rec709 or 100%srgb?

Suggestions. 709 and sRGB have the same three primary colors and white point chromaticity, that is, their color gamut is the same. But the latter is 100%, so the latter is more colorful.

RGB three primary colors have different definitions in different standards.

For HD environment, ITU-R recommends BT.709(REC.709). The color coordinates of the three primary colors are the same as sRGB, and the white point is D65. So far, sRGB and REC.709 seem to be exactly the same.

App application

With the in-depth understanding and research of tricolor, people's application of tricolor is more and more extensive, and they are more and more involved in people's lives and work. Tricolor fluorescent lamps provide more abundant light source systems for human beings, and people are increasingly applying tricolor products to the fields of painting and photographic lamps.

Characteristics of tricolor energy-saving lamps-Taking high-frequency energy-saving lamps as an example

(1), small light attenuation value and long ignition life. T5-28C high-frequency energy-saving lamp has a small attenuation value when actually ignited, and the luminous flux maintenance rate is 90% after 5000 hours, and the ignition life is 8000 hours.

(2) The power grid has strong environmental adaptability. In the voltage range of 180 V-260 V, it can be reliably ignited. It can be applied to power grid environment with serious voltage drop and harmonic interference. Such as: steel rolling production workshop, resistance welding machine application workshop, high-power AC welding machine application workshop, etc.

(3) Strong adaptability to the space environment. It has good low-temperature ignition characteristics and can be reliably ignited at-15℃. It can be used in the production environment with temperature +50℃ and humidity 100.
