Flash diagnosing update

Ink... it shouldn't.

Every bulb in your house is wired in parallel. They don't burn any hotter. They draw the current they need to. If anything if the current was restricted they would burn lower due to less juice to supply to each of them. More load.

Batteries in Series cause this to be true but that isn't the case here.

4 bulbs in series between two legs of 3-phase will create a lower resistance circuit than 3 bulbs between two other legs of three phase. But I'm probably barking up the wrong tree on this one.....

I also would have concerns of the SSR's ability to switch as quickly as required for PWM switching for bulb intensity control if that's what they are using. A tiny bit of switching lag would easily cause one bank of bulbs to run hotter.

You might need matched relays for the flash to operate evenly as switching speed would need to be virtually identical or you're in trouble.

Are other companies using this type of control circuit to attenuate bulb temp?

Not M&R. We are old technology! LOL!

Actually Rich you do use this technology on your higher end flashes ... you may want to check your statement ... Mariusz laid it into the circuit years ago (back when your flashes were blue) ... I will extend you a professional courtesy (toclarify your position)

You have bad information

I guess you are right ... that board in the pics must be a copy of the M&R board in Cayenne LOL

When will you be filing a Federal Lawsuit against them

All right now I went ahead and did what you said this morning Robert, I placed the new SSR in the zone with four bulbs. Ran all day then bang see pic below. The thing looked like an arc welder when it went.

SEXY ... check the rest of them as well ... also ... did the new fans come in :-?

Note: this is for all folks reading ... its a good idea to spin your bulbs periodically to scuff the contacts ... especially if you run discharge, waterbase, solvents, etc. and clean your fans/vents/filters !!!
