Strobe Failure by Make and Type:
A number of Wetpixel members write of their strobe failures (refs 1 to 3). To better understand these failures, they are abstracted and listed here by strobe make and type of failure.
User flooding: 3
Inon strobes Z240 and Z330:
Total failures: 7
User flood: 2
Battery failure, user fault: 1
Strobe internal failure: 1
Dim strobe flash: 1
New Z330, not working: 1
Partial failure - Z330 Ready Light turns On before ready: 1
Potentiometer leak from shaft corrosion: 1
Sea & Sea Strobes:
Total failures, 35
No user floods posted, but descriptions were unclear
YS-D1 Flash tube failure: 10
YS-D2(not J) Flash tube failure: 10
Body flood (not battery compartment): 3
Switch leak: 2
Cracked strobe body: 1
Does not turn on: 2
Erratic firing or TTL defect : 7
With user floods excluded, the results are:
Ikelite strobes had no posted strobe failures.
Olympus had 1 corrosion failure.
Inon strobes had 4 failures.
Sea & Sea 'made in China' strobes had multiple failures.
Wetpixel posts are the only published reports of underwater strobe failures I could find, as strobe company annual reports and the number of strobes sold and of failures are not published.
Strobe failure reports have become common in Wetpixel while those of other underwater photo equipment, such as cameras and housings are rare (refs 1 to 3).
In terms of reliability and response to problems, Ikelite seems to be the only company I know of that communicates with customers and provides satisfactory strobe service and repairs.
Let us hope that the causes of YS-D2 strobe failures have been corrected by Sea&Sea now that it has relocated its strobe manufacturing from China to Japan (and re-labeled its strobe as the YS-D2J).
In closing, a striking post by Wolf Eel (2) helps understand part of our strobe problem:
" I've had the exact same thing as Custom happen to my D1s. The flash tube design shortcoming/flaw was not addressed in the D2, which is why I did not upgrade to them. SEA&SEA's explanation to me was [paraphrasing] "we are very sorry but this can happen because the flash tubes are those taken from conventional land based flash units and simply housed in an underwater housing (sealed, traps heat) - we do not have the resources to design from the ground up a flash tube assembly just for this strobe.”
