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).
Manufacturers usually provide light output data at the optimal temperature for each lamp type in their catalogs: 35Â°C (95Â°F) for the standard T5 and T5 HO lamps and 25Â°C (77Â°F) for the T8 lamps. Light output data for T5 lamps at 25Â°C (77Â°F) and for T8 lamps at 35Â°C (95Â°F) are also available from manufacturers, however.
