[Konvas] lighting pars vs. fresnels (off topic)

>>Still, LEDs are the future....anybody tried shooting with  them?
 
 
Most of the LED instruments I've seen that said they are LED PARs or  
whatever, aren't really PARs in the true sense... in that there is not a PAR  
reflector that directs the light.  Most of them are called PARs because  they are 
simply housed in a PAR-shaped can.  Maybe there are some true PAR  LED 
instruments, but all of the ones that I have see are not.  The actual  LED elements 
themselves are directional (usually around 30 degrees if I recall),  so there is 
no reflector needed, PAR or otherwise.
 
LEDs are probably the wave of the future, but not there yet... at least not  
in this application.  They exist (and are pretty useful) in banks, used as  
daylight-balanced softlight sources... but they do not yet deliver the lumens or 
 punch to replace conventional hardlights in a lot of applications.  One  
fairly affordable one that I've seen, for example, is an instrument that's a  
little over a foot square, a bank with 1000 LEDs.  It's said to deliver the  
equivalent of about 900w tungsten, if I recall correctly (and it's about  $900).  
To get an instrument with the equivalent output of, say, a 1200w  HMI... well 
that would take more like five or six thousand LEDs, and still  wouldn't have 
the same kind of throw or punch.
 
I haven't gotten around to trying them yet, but I do know one guy who has  
started using LED banks in place of Kinos for softlight use.... and claims they  
work very well... good color balance, no flicker, etc. (although he says they 
 are a bit harder than a Kino and a LOT harder than a tungsten instrument in 
a  softbox).  And one of the big advantages is that most of them are 12v....  
you can run them off a battery belt or Anton Bauer brick, etc. for literally  
hours.... something you can definitely NOT do with any equivalent Kino or  HMI.
