Sunmaster Metal Halide Cool Deluxe lamps are, we believe, the industry leaders.
Using MH lamps in veg as opposed to Dual Spectrum lamps throughout the plants life results in healthier plants early-on and shorter internodal length corresponding to increased yields come harvest. Always remember to switch to a Sodium lamp (pure red or DS) for fruiting or flowering plants when the time comes!
These 7200K versions are also the lamp of choice for adding extra blue spectrum to a lighting setup that contains mostly sodium lamps â€“ adding around one halide lamp to every two sodium lamps dramatically increases overall plant health and is generally considered by most experienced growers as the optimum lighting mix.
These are, we believe, the best metal halide lamps on the market and they wont break the bank.
