ISO is a must in getting accurate measurements from the light meter, but it is not required if you are not using the light meter function. Shutter speed is not typically an issue for work when ambient light is low (i.e. if you take a photo with no flash but the same settings otherwise, your image is completely dark), and also not required if you are not using the light meter function.
I presume you are using the same reflectors and they are positioned identically as the Bees were?
When you say 1/4 on the Bees and 3/4 on Einstein, is this stating the porportial position of the range of the slider, or is it actually 1/4=-2f an 3/4=-.5f? These are very different. In otherwords, on the back panel of the Bee, if the slider is in the middle of its travel, then that is 1/4 power, not 1/2 power. On an Einstein, halfway on the bar graph is more like 1/16 power.
Because the range of Einstein is longer than the range of a Bee, 1/4 of the way down from full on Einstein is -2f, while halfway down on a Bee is -2f. You can also note the Ws rating in the horizontal blue bar of the CC for each light.

Thanks, I think it is something I just need to get used to, two different animals. With the 1600's I would set to 1/4 half of the half way point, so I assumed I could get the same output at 1/32 on the Einsteins. But not a big deal, they work flawless and make awesome images so it's all good. Thanks for all the replies.
