Impact Studio Lights for Group shots?

Hi All, I've been doing parties and weddings lately and wondering if These: http://www.bhphotovide​o.com …EG&addedTroughT​ype=search would work well to use as in for group shots (7-10 people max) as well as for senior portraits. Will these fits my needs? Do any of you have impact or heard about this brand before? I want to buy a "good" studio set for about $500.00, am I going into the right direction?
Thank-you

The description of this kit says good for a group of 3-4 full length, also the units are not fan cooled, and they didn't mention anything about the modeling light adjusting to the output power of the strobe.

The units not being fan cooled is enough for me to pass on this unit, but that was one of the requirements I was looking for when I was looking to purchase a monolight.

I have no idea concerning the quality of the cited flash units, but the lack of fan cooling in itself is not something that should cast doubt on the overall quality of a flash unit.

There are all sorts of very high reliability and high quality flash gear from numerous flash manufactures that do not have fan cooling.

Fan cooling is only one aspect of flash design. Given the right design, it may not be needed.

I personally have used all sorts of flash gear (Speedotron Brownline, Speedotron Blackline, Alien Bee, Novatron, White Lightning, etc). Some of of it had fan cooling, some did not. All of this gear as typically functioned perfectly over an extended period of time.

On lower powered studio flash units, it is likely very easy to design a flash unit that does not require fan cooling.

Alien Bee units have a very novel power supply that negates the heavy power transformer, I suspect this design approach, along with a thick plastic case, necessitates the need for a fan, even on the relatively low powered B400 unit. Many of the older White Lightning monoheads had a huge extruded aluminum heat sink casing with fins and did not need a fan. Note that both of these units are from the same manufacturer (Paul Bluff).

One big downside of a fan is the racket. Most are relatively quiet, but not as quite as no fan.

Enjoy! Lon
