The Spider Farmer is powered by 301s w/ a 100 watt driver. The TS1000 is powered by different diodes and is driven to 150 watts. The TS1000 is 743 umol at 18"the SF 602.. If we judging on output alone the TS1000 has higher amounts of photons at given height so it is a better light. But if we were judging on efficiency the 301s are slightly more efficient so the SF-1000 might be a better choice there.. But really what the next concern would be is Cost and Warranty coverage.. Make the right call for your wallet.
Both are comparable but I can only speak on Spider Farmer. I have the SF1000 and SF2000 and had great results with them so far. You won’t be disappointed with them or Mars Hydro though.
