The light's twenty-seven watts. I'd go DIY rather than Excel. It's a bit more work, but the results are more than commensurate. Especially if it's at the office and you have the DIY CO2 hooked into a diffuser. People will ask about the bubbles and you can go on to explain about how the yeast exhales and gives off CO2 and how that feeds the plants and how it's all carefully controlled ecosystem on account of the lights, the plants, the fertilizers, the substrate, and the fauna, and by the time their eyes glaze over after hearing what to them is incredibly boring stuff, they'll be out of your office having forgotten to give you the work they meant to give you right before they asked what the bubbles were.
