The M400/HOR/HTL/ES is a 400 watt lamp from EYE HORTILUX™.

HORTILUX™ e-Start Metal Halide is a new family of lamps designed for use on electronic/digital ballasts.

This improves lamp performance over the life of the lamp while improving results in your indoor garden.

  • Wide vegetative-sustaining spectrum for beginning stages of plant growth.
  • Extended Peak Spectral Output: the quality of the spectrum is maintained over a longer lamp life.
