In Topic: Our Strobe Problem

18 May 2019 - 05:53 PM

I'm in favour of right to repair, and I found inon's "we just replace the entire internals" approach frustrating and slow. But then I discovered a local electronics (non-strobe, non-underwater) place to replace tubes and life got much easier.

 

The best advance on reliability for all the smaller strobes would be an overheating cutoff switch. Burnouts shouldn't happen. Instructions to stop using the strobe for 10 minutes if you shoot a few times in a row at full power are ridiculous.

 

That said, I think strobes are the most reliable and certainly the longest lasting component of my entire rig. I started in underwater photography in 2009 using ikelite substrobes 150, 225 and 400. These were taken out of the garage, from my dad's stash of gear, originally purchased sometime in the late 80s or early 90s. They worked great for a couple of years until I eventually broke them and bought inons. It's just a shame that each strobe weighed almost as much as my DSLR aluminium housing...

Looks spectacular - I would love to go. I assume from the black and white that the vis was not ideal. What was the average vis situation across the trip?


In Topic: Strobe Failure A note of caution

I have had issues with the Z240s burning out both in air (caving, used cautiously) and in tropical waters when shooting on full power. I had tubes replaced locally about half a dozen times. A thermal cut-off switch is not that hard - it's frustrating that the strobe manufacturers don't think this is important. More frustrating because inon won't replace tubes, they just replace the entire internals and charge accordingly.

 

I have not had any burn out issues in cold caves (6 degrees air temp) or in temperate waters (4 to 22 degrees).

 

I shoot on full power most of the time.

I haven't heard of anyone. I'd be interested in giving it a run out of Melbourne but it's going to be cold...

 

Things floating around in the EAC could be interesting.

Not to mention, if you shoot a Z240 repeatedly on full power in tropical water then you will melt the capacitors pretty quickly or the tubes themselves if the capacitors keep up.

 

The Z330 is meant to have overheating protection. Or is it just misleading you into thinking you're shooting repeatedly on full power when in fact it's only 25%? Given the use of high voltage capacitors then maybe this will be less of an issue. I'd be interested to see the internals of a Z330 to see what the heat sink looks like, if any.
