You need to get the 6 - 26 watt CFL's and that makes 156Watts for use in a rubbermaid grow box. See google post on Rubbermaid Stealth growbox

jon101 Reviewed by jon101 on . rubbermaid growbox light. ok, I've got two 18 gallon rubberaid tubs painted white on the inside with a 60mm intake fan at the bottom, and a 30mm fan at the top.So my question is would two 15watt 900 lumen cfl bulbs be enough light for one or two plants? Rating: 5
