Donkeys, also called burros and asses, are found throughout the world. They look a lot like their cousins, but have long, floppy ears and tend to be stockier than horses or zebras. News
The above is not a true Color Temperature chart. Instead it is a hybrid, showing the color temperatures of light sources most commonly encountered in professional imaging. In our scale, tungsten-halogen has a color temperature of 3200Â°K. Household fluorescents are accepted to be around 4500Â°K, depending on the lamp. (They are shown for reference, but would not be part of a true Color Temperature chart, for reasons described below).
Fluorescent lamp efficacy is dependent on lamp temperature at the coldest part of the lamp. In T8 lamps this is in the center of the tube. In T5 lamps this is at the end of the tube with the text stamped on it. The ideal temperature for a T8 lamp is 25 Â°C (77 Â°F) while the T5 lamp is ideally at 35 Â°C (95 Â°F).hey are built in the same fashion as conventional fluorescent lamps but the glass tube is coated with a phosphor that converts the short-wave UV within the tube to long-wave UV rather than to visible light.
