Problem with most is that words are too small and art too big. When this is reduced to say a business card or small 1" thumbnail, you would not be able to read the words. The top 3 I choose was because the words were bigger.
In order to make words big but take up little space, stacking the 3 words "landscape lighting world) like #1 ranked logo above is probablyt a good idea.
Some examples to try:
-Try one like HOME DEPOT logo, the Volt logo on my website, Bose speaker logo, --simple design with name/text being the focus, but uses stylized text to make into a unique logo.
-Maybe the "O" in world as a the earth or a globe. Maybe the "O" as a green and black bullseye?
-Maybe a solid green oval with landscape lighting world wittein inside it--landscape lighting stacked on the top inside of oval following top curve, world on botton inside following bottom contour.
Less interested in the overused icons in our industry (spotlight or tree), more interested in simple made-up icon, could be a simple as a green dot.
