We like the color of
#5 and
#6, so keep those, but not
#1 or
#2. Try blue for those.
The image reminds me to much of lightning, or electricity. Our industry doesn't have anything to do with that. We would prefer the image not to be industry related, but more of an abstract image. Something new and unique, that way we can use it as our trademark image on the website, business cards, etc. Please also change the font for the word "voltage" as it also reminds us to much of electricity.
As for the placement of the image, we like
#6 better than
#5, so keep it to the left of the website name.
We also like the way you put the word "low" vertically.
