h0001244師兄,
支580 EX II用左幾耐,要換閃膽呀?
$1,300元都好貴喎.
我平時如果知道會多用外閃,都會帶多一支或兩支去替換,
等支燈可以休息抖返一下,聽講會壽命長一點.

Touch wood all my flash is still working good though they have been stayed with me for 4 years already.

Last time I saw a wedding photographer can't continue his work because of the bulb went out....
After that I phoned CS to ask the price and surprisingly that 580 is double the price of 430

most dead flash are in fact dead circuit board, 3-4 years ago, I use a 550EX with some Ni-Cd battery without external power pack CP-E2, after flashing serious of full power flash, the battery was so hot that melt the plastic battery tab inside the battery case, the flash was dead at that moment. But as the flash bulb and the circuit board were still ok, after cleaning the molten plastic, the flash can now be used. That 550EX is still used today

Obi Ching,

I am not quite sure whether that wedding photograher is having dead circuit board or fall of flash bulb. After the failure of the lighting, he immediately replace the flash with another one, and he said it's related to the flash bulb. I assume he has some experience on such situation.
