Below is some Google Translated information from Canon marketing material about the upcoming Canon Speedlite EL-1, which is the new flagship Speedlite for the EOS lineup.
Canon Speedlite EL-1 Information (Google Translated):
Stabilization of light emission amount and improvement of continuous light emission performance
By adopting a newly developed highly durable xenon tube, it suppresses variations in the amount of light emitted and realizes stable light emission.
Equipped with a newly developed active cooling system that uses a blower fan and glass panel. By circulating air inside the strobe, the temperature rise of the heat spot is suppressed. Heat resistance is improved by combining with a highly durable xenon tube, and the number of continuous light emission is about 160 times.
Minimal emission of 1/8192
By adopting a newly developed xenon tube and improving the accuracy of light emission control, stable minute light emission of at least 1/8192 is...
