Cool 1000W
Grow Lights1000W
The Cool 1000W is the largest lamp in Sunmaster's vegetative COOL range, at 5,500K with 1,400 µmol total output, 1,250 µmol of it between 400 and 700nm, and 320 PAR watts.
That is a lot of light for a veg room, and the spectrum is weighted where a veg lamp should be — 50% of the spectral energy between 380nm and 495nm, in the blue and violet. Plants under it stay short and thick rather than reaching.
Rated 10,000 hours, burns in any position, part number 80099. This is a mother-room or large-veg-area lamp; at 1000 watts it needs the extraction to match, and it is not the lamp you flower under.
