The NEW Sunmaster Dual Spectrum lamp is a radically new, scientifically-developed lamp developed to deliver exactly the right light frequency to your plants at the crucial stages in their development. Dual Spectrum lamps offer superior lamp performance and are fully compatible with existing fittings and ballasts to deliver exactly the right light frequency at the right time. This is a discharge lamp and requires several minutes to restart and come to full brightness after a power interruption.  For total load, add auxiliary (ballast) watts to lamp watts. This lamp may be operated in any position. Contains mercury. Please dispose of in a re-cycling facility. Available in 250, 400w, 600w and 1000w.
