It puts out 15,000 lumens and about the same heat as 15k lumens of cfl's would. I don't know what 26w cfl's put out for sure but it's probably in the 1500 lumen range so it would be equal to about 10 of them I'm guessing except for better because of more penetration and because HPS is just superior to CFL spectrum wise for veg.
