I sold some 20W LED T8 lamps and 9W Bulbs to my customer,and he found that partial red light (with the traditional fluorescent tube contrast)
What is going on? How many LED color temperature is the traditional color temperature? ? In addition, I hear that was because the Asian black eyes are different form the blue eyes? :Sp
Just like led’s they come in all sort of different flavours. It all depends on the temp selected and the subtle colours of that tube
There are several temperatures to select, like in the case of the LEDs. In fact, I think the color comes from the same principle, the phosphorescence of a phosphor layer in the glass pipe excited by the uv, in this case produced by some gas plasma. So if the amount of phosphor varies, so does the color. (It’s maybe not phosphor, but it works the same way)
I can recall same brands use the color temp, but most popular brands use their own numbers (osram, Phillips! you can use their data sheets to convert) and others (i recall sylvania) use names as daylight, cool white, universal white, warm white.
The most popular around here was daylight, but I suppose it changes depending on local habits
If you see the tube, in both sides it has the specs. One of them is the color, and you can find the kelvin temp equivalency googling it (remember it can be two letters, or three numbers normally)
