Einstein has approximately double the air volume of WL and ABs fan, has four times the air inlet, properly located on the bottom where the air is coolest. The airflow is carefully directed both through the unit and out the front and top, blowing directly into the frosted dome, with ample room for the air to escape as it exits the dome.
The cooling path follows expert thermodynamic engineering - bringing the air in at the coolest point, passing the air flow first through the most heat sensitive components, then on to the hottest components. Several temperature sensors control the speed of the fan and shut the unit down if excess heating occurs in any location. The charge voltage is regulated to 1/50 f stop and multiple over-voltage sensors protect the unit. There are no compromises in the Einstein design whatsoever. For information to Unlimited, the IGBT circuitry consumes approximately two watts total when fired at every recycle. You are not "Buff" (thank god) and your technical analysis is of no value to me, nor I doubt to any other reader here.
As for Ellis Vener, he is a very well respected writer and reviewer for Professional Photographers of America, the premiere educational and professional organization in America, and other publications. I have never met Ellis but know from experience when he reviews a product he is completely unbiased and objective.
The question remains for Unlimited . . . just what are your expert qualifications, beyond spewing hot air and hatred?
