My first studio strobe

Yes, I've finally got a proper studio strobe and softbox. Using speedlights for off-camera lighting can be more convenient as they are certainly more portable, but recycle times can start stretching out once the batteries begin to lose their power. The strobe, being mains powered, will recycle in around 1 second every time (maybe 2 seconds if you are using it at full power).  The strobe also has a modeling light which helps reduce the trial and error with positioning light and subject.

Having looked at the strobes available in the normal camera stores and online, I couldn't justify the $400-500 price tags I was seeing for even fairly modest 200WS strobes, and the cost-effective Alien Bees that everyone seems to rave about, appeared to only be available for 120V (not much use to me here in Aus). So it was off to eBay for a search.

There are hundreds and hundreds of ads on eBay for cheap strobes, and lighting kits comprising multiple strobes, but be careful...  while the price may look attractive, just check out the specs. The one thing I saw time and time again on pretty much all the cheap models, was that their power range was shown as 8 'steps', or adjustable to 1/8 power. This is NOT equivalent to 8 f-stops. From full power to 1/8 is actually only a range of 3 stops - the equivalent of going from f/8 to f/11 to f/16 to f/22. I really wanted to try and find a strobe that had more control than that - similar to my speedlights which have the ability to go down to 1/128 power, which is a 7 stop range.

I found 2 potentials.  The first was a Pegasus P300A 300WS head supplied by a company called pro4aussie based in Victoria. It was around the $100 mark, but unfortunately, they were out of stock and could not supply me one back in March. Since then, the postage on their eBay ad has gone up to a whopping $100 - which is usually a sign that they still cannot supply the goods but don't want to take down the advert.

So option 2 was the DSLRKIT Flame-200 - a 200WS head for about the same price, but coming from China. After consulting with the dealer, it was (rather vaguely) confirmed that this head should have an 8 f-stop range, not just 8 steps from full down to 1/8 power. I gave the details to my family, who were clubbing together to get this for my birthday.

When the light arrived, my first disappointment was that it came with a European plug on the end of the (extra long) mains lead, but after a quick unplanned trip to Bunnings to buy a new plug, I was able to plug it in and test it. Everything worked, and it flashed OK (phew - always worry about anything glass or fragile coming through the post). The next slight disappointment was that the head has a 2 digit LED display on it, so I had assumed that the power would be adjustable in decimal increments as well as full stops - or at least in halves or thirds... but no, the power settings are 10, 20, 30, 40, 50, 60, 70, and 80.  So what is the point of the second LED digit, I hear you ask?  Yes - I'm wondering the same...  Oh well, this is actually only a very minor inconvenience, and if I ever really need to be that precise, then I can move the light stand slightly, or make the adjustment in camera. Just one more observation - the modeling light power is not adjustable, as it is on the more expensive strobes - I'm not sure I'd even class this as an irritation - simply an observation.

I have used the strobe on 3 photo shoots now (article on those due in the next couple of days), and have been very pleased with the ease of use, and consistent results. I use my Cactus V radio triggers to fire the flash (and there is a very convenient cold shoe on the underside of the casing so the receiver does not have to dangle on the end of the cable), though it also has a light sensor on the top and can work on 'slave' mode (haven't actually tried this yet).  The controls are very simple - plug it in and switch on the main (green) power button.  Switch on the modeling light if required. Adjust the power up or down (from 10 to 80, where 80 is full power) using the + and - buttons.  There is a test button to fire the flash manually, and a button to turn the audible beep on and off. If you have that on, then it beeps when the flash power has recycled. As well as the audible beep, there is a bright blue LED that shows when the flash is ready to go. And that is all there is to it. The front end of the head has a universal mount, with a nice recessed ring in it, that helps to secure a softbox or other fittings, and reduce the possibility of them slipping off.

So, the moment of truth... Today, I set up a test to make sure I would actually get 8 stops of adjustment.  By my reckoning, if I set up a shot with a very small aperture and the strobe on full power, then decreased the power and opened the aperture by one stop at a time, then in theory, all the pictures should have the same exposure. If you look at the settings in the table below, you can see that my lens doesn't have 8 stops of latitude, so for the final 2 tests, I had to also lengthen the shutter speed to achieve the same exposure value.

And here are the results (excuse the hastily thrown together testbed)...

 ...so not totally consistent exposure across the whole range of adjustment, but unless you are doing an exercise like this, it wouldn't really matter, as you would most likely be adjusting the light, aperture, shutter speed, angles, distances, and everything by eye anyway.  The important result for me is that the minimum power setting IS actually 8 stops away from full power, and not just 1/8th of it.

So am I pleased with it? Yes - absolutely.  A minor setback with the plug at the beginning, but otherwise, I'm very pleased. It may not be the most powerful strobe in the world, but I don't feel that at this point in my life, I need multiple 1200WS strobes to light a huge studio from all angles (since I don't have a huge studio), and it fits my needs.  I'd certainly consider getting a second one if my move towards portrait and/or product photography goes as I hope...

Until the next time,
