In looking at a number of different vendors, I've noticed that there can be quite a price differential, to the tune of several hundred dollars or more (say between Alien Bees and Elinchrom - or whatever, doesn't really matter).
Now, I know that you usually get what you pay for, but I don't have any strobes or softboxes or light stands or radio transmitters to play with. So, for those discerning studio lighting users out there - why pay extra for lighting equipment? What bang are you getting for your buck?
Bang for the buck--> Consistency, repeatability, power range, total power, control, reliability, wireless firing; All these things separate the higher end equipment from the lower end equipment.
I've been asking myself similar questions to what you've asked here. If you do a search for Alien Bees in the lighting forum you will find that AB's have a color shift at lower power. When you look at higher end lights you will see that they move from rocker or slide analog power settings to digital settings. Even when power output is identical, some lights recycle faster than others. Light duration can be a factor also. Many of your higher end mono lights and generator/strobe combos have short duration flash tubes suitable for freezing action. Some lights let you vary power over a 5 f-stop range, others, 6, 7, even 8 f-stops. Most digital systems give you 1/tenth of an f-stop control over power output. Some photographers need that control, others won't use that kind of control properly or simply don't desire it.
Power input matter also. Many of the higher end models can operate on voltage below 110v/115 that would toast other appliances/equipment you own. Helps keep them alive on location shoots in countries where power isn't as stabil as it should be.
If you go with monolights that control output in 1/10th of a stop over a X f-stop range, you have to set each light individual. If you go with a generator/strobe set up, you control each light from one location. Your higher end generators will also let you control the group in 1/10 f-stop settings from a single adjustment knob. Higher end monolights and generators will offer built in radio receivers. Profoto's built-in wireless is compatible with Pocket Wizard's.
Currently I'm shooting with 580exII's and 550ex's. It's taken a while to locate the above information and decide what kind of studio light set up I will go with.
Some people like the redundancy of mono lights. Others like the control a generator can provide.
hope this gives you something to think about.
