You know i looked into it, and when you buy the bulb with the ballast, the ballast that comes with it is a 120v ballast, so i dont think it will pop. And i checked it out, the 430 Watt Son Agro HPS light bulb has a 30% increased blue spectrum in addition to the red/orange spectrum needed for fruiting, flowering and budding. So im sure this would be the better choice. (thats prolly why i only have one apposed to six) But if anyone knows if it would work in my 400w HPS ballast, that would be great.

SittinStoney420 Reviewed by SittinStoney420 on . Which Light To Use? Is There A Difference? PICS Hello again everyone, I was wondering if there is a difference in 400w HPS lights. My buddy gave me 6 bulbs that say "LUMALUX LU400 SYLVANIA" He also gave me one bulb that says "PHILIPS 430w SON AGRO" My ballast is a 400w HPS. Would one of these be better to use than the other. Also, ive heard that older bulbs can have different effects on your plants etc. How should i choose which one to use out of the six? Picture: One HPS is already in my ballast and not shown, but in the pic, the 5 Rating: 5
