Yeah it's about 840 true watts from wall. Although all different brands (whatever was on sale at the time), the average rating of each bulb is around 14 watts. Most are exactly 14 watts, but some are 13 and some are 15 watts. I have extra sockets in my fixtures in case I thought I needed more, but this seems to be pretty optimal - 33.6 watts per square foot for flowering.Awesome. Is that 840 true watts?
