T12's can be 3000k-6000k @ up to 3600 lumen, they make VHO four-footers that go higher
4x5 Reviewed by 4x5 on . Florescent Lighting Planning on gettin some new floro fixtures and am wondering which is brighter/better the T5's T'8s or T12'. Will have 2 2 bulb fixtures with one cool and one warm bulb in each. As these are just to keep some moms and a veg box going. Thanks Rating: 5
