Lusana Studio Fresnels

[HockeyFan12]

Has anyone tried these? How dissimilar are they from Arri fresnels?

I rarely use my Arri lights anymore because everything is daylight balanced these days. I was going to install 12v 40w LEDs (150w tungsten equivalent) in them, but didn't want to ruin such nice lights with cheap LEDs. (I figured out how to re-wire them, but it would be somewhat destructive.)

Has anyone tried these? They're about the price of a pair of Arri barn doors... and no need for scrims when you have a voltage dimmer.

I already have some LEDs that fit the Arri fresnels. Anyone tried these out? Are they wired about the same? Are they real fresnels or something terrible? 

I'd buy real LED fresnels but these are for personal/personal promotional products... so I can't justify the cost. With the 15% off coupon and given that I own some 40w LEDs already I can definitely justify these. The option for battery power is very important to me.
