MH lamps are a very efficient source of light for indoor gardeners. The light radiates strongly, so the MH lamp can penetrate the foliage of your plants. MH lamps give a more natural light and a more continuous spectrum. The efficiency is 8500 to 13000 hours. An MH lamp needs a ballast or a plate of the same wattage to work.
Attention! The installation of MH lamps in kits with standard ballast must be wired by a qualified electrician
