Double-ended (DE) bulb, designed for Lumatek 1000W Pro 400V electronic ballasts, for healthy plant growth.

Double-ended HPS lamps are more stable than traditional ones as they have a 10% increase in light intensity and PAR/PPF spectrum output. The increased intensity allows the lamp to be placed further away, thus the light is more uniform.

The ceramic tube (PCA) allows the lamp to operate at higher internal temperatures, thus increasing color production, yield and efficiency.
