Source Four PARs
 

They're amazing. That's all I have to say. Bounce'em, diffuse'em, blow through silks, whatever. You can even stick'em in softboxes with Chimera speedrings!! Not bad for a piece of gear that costs $150. The output is amazing. The beam spread is even, the bulbs are way more efficient than a regular tungsten, and the color temp even seems to be "cooler." I own Arri daylight PARs and tungsten lighting packages and these instruments have proven themselves to be indispensible on even all-5600k shoots (color correction required, natch). Do yourself a favor and pick a couple up.
