Hello folks, first off, Happy New Year to one and all! Just bought a Proline L-300F strobe and as with anything made in China, this one was relatively affordable. It also had no documentation at all, no instruction manual or even leaflet to guide the owner on its feature and setup. So I am writing in the hope that a DPP guru could tell me if this particular strobe is safe to hook up to an EOS 40D body using a PC synch cord? I've read belatedly from here-- http://photonotes.org/articles/eos-flash/index2.html#trigger-- that voltage damage is subtle and cumulative, and just because it worked fine the first time, doesn't mean the camera's circuits aren't getting fried every subsequent time it's used.

I would use a wireless trigger like Merlin but with little left budget-wise, I'll have to use the included PC synch cord instead. Any thoughts on this? Are these strobes rated with low trigger voltages or are over the safe 6V range? Any help welcome and thanks in advance!

Why not check it with a VOM? If you do not have one, ask your friendly electrician to check it for you.

Bettery yet, buy yourself one. The compact ones ranges from 150 to 300 PhP.

yull need a voltmeter, turn the flash on then measure the voltage from the main pin under the hotshoe, put the positive probe here, and if you look at the side of the hot shoe there is another metal sticking out put the negative probe here. You do not have to fire the flash, its the standby voltage that you have to measure...

Can the strobe be fired w/ IR trigger? If it can, I would say use that instead - you can get an IR trigger.

Thanks guys! I did try to google this thing and came up with nothing. I then remembered recently there was a site I stumbled on-- MadeinChina.com, for products with the "M-I-C" label, and tried that. Lo and behold, there it was. The specs for this strobe give a trigger voltage of 5volts, which is super. But...I'm still going with your advice guys. I'm asking the neighborhood electrician to test this baby and see if it matches the specs...as with anything from China, its "Buyer Beware" :-)

Thanks again, your tips were helpful...
