LED green night fishing lights

Has anyone had good results using green portable LED fishing light.I did not want to drill any holes on my transom below the waterline, plus it seams the cost of these good lights gets expensive in a hurry. I will probably use only a few time a year to try and put the grand kids on a few trout. I do not mind spending the money for a quality product. What does the 2Cool members think about something like this.
