#4 is my favorite of yours right now. I do like the attempt to use "power" in the logo to go along with our product. Lightning however is not a great link to power for us, since we try to promote safety :) I would like to see more 2-color ideas. Less gradient / color shifts.
Hi, Thanks for comment, I've added some variations. I used the similar green as Byrne logo that I designed. And maybe again a water drop to show safety ( #96 ) Any additional requests are wellcome.
