anybody can help me !
I can not check the color temperature of light philips
Colour temp and rendering index are usually part of the product code 842 is rendering index 8, colour 4200K, 956 are rendering 9 colour 5600K, 830 is R8 3000K usw
In my experience, the ### designations are usually not found on <70 CRI lamps and newer consumper market lamps.
For example, F34T12/CW/ is around 4100K 65 CRI, but F34T12/CW/ALTO is all you see on the lamp
On consumer market lamps, you might only find markings like F32T8/Warm White
