Well I got my sample unit today to do testing and post results but it has met with an unfortunate end.
I had it and a P73 set up and pointed at a wall 25 feet away and while adjusting them to be perfectly parralel for a side by side spot size comparison I shorted the leads and LEDed the diode.
But I did get a general idea on how it compares and the line size with a G-2 is about 4/5 that of the P73 with a G-2. Something like this.
I will get another and finish the testing but at least I have seen it is slightly better than the P73. Just wish I could have got some power readings before it went. Sadly these are all the photos I got before killing the diode.
Also I got a shot of the dye. Excuse the crazy decanning as I did not have a lot of time.
