Kendall is running 9 225watt ultras and a Kopter Converter off a 3000 watt generator. (the Kopter converter lets you run your trolling motor off your generator and a single battery all night long)

Getting the ultra bulbs is cheaper than getting a bigger generator.

Homegrown Enterprises sells the ultras online http://www.homegrownenterprises.com/

BTW, I just bought a new 3000 watt 'honda clone' genny for 250.00
