Sorry did not see the 250 a 250 watt HPS produces 25,000 to 28,000 lumins
Jerry Garcia 2007 Reviewed by Jerry Garcia 2007 on . 200w CFL vs 150w HPS So I have 200w of CFL lighting going on 4 plants to cover approx. 3 square feet. Question: Would my yield increase if I used a 150w HPS instead to flower? Also, if I went up to a 250w hps would that double my yield for just another 100 watts? Say 6 square feet instead of 3. And how much power do all these different lights actually pull when you include the ballast? Rating: 5
