SolarMax One Everything you need in one lamp! One lamp with two simultaneously operating arc-tubes, a 600 HPS and 400 MH, that are optimized for peak performance with your 1000 watt HPS ballast. SolarMax One is the best of both technologies. Lamp manufacturers have pursued the ideal spectral output for plant growth for years. The biggest advancement made in H.I.D. sources for plant growth was to enhance the inherent deficiencies of either HPS (not enough blue) or MH (not enough orange/red). The fact is that neither technology can be altered enough to be truly optimum for plant growth. The SolarMax One has 100,000 lumens of targeted output with a correlated color temperature of 2850º Kelvin.
