Advanced Nutrients BaddAss HPS Bulb - 600 Watt At a massive 90,000 lumens, your Red Diamond 600 Watt HPS bulb gives you complete bragging rights over any other 600 Watt bulb available... because it has the highest initial lumen reading of any bulb in its class. Your 600 Watt Red Diamond Bulb is ready to work - immediately. With a strike time of less than 4 minutes, the Red Diamond 600 Watt bulb reaches full lumen output faster than any other bulb in its class. For best results pair with a BaddAss Low Frequency Digital Ballast. Your Red Diamond 600 Watt HPS bulb is protected in an exclusive "cocoon" of packaging that you'll only get with BaddAss Bulbs. Plus, each one of your Red Diamond bulbs comes in an Oil Guard protective removable sleeve which will prevent the oils from your hands from ever coming in contact with the surface of the bulb. This is important because oils from hands and fingers can cause hot spots that severely damage a bulbs surface, even worse, in some cases leading to bulb rupturing or exploding. Your Red Diamond 600 Watt HPS bulb is painstakingly built and held to strict AQL standards. If even one slight defect is found on even one bulb, we go all the way back to the beginning of QC to our visual, functional test and burn-in stages and go through the whole testing and qualification/approval process over again. You'll enjoy a powerfully enhanced flower spectrum that will give you over 99% color consistency thanks to a unique gas combination that blasts out a firestorm of red light!
