hammondegge Posted June 19, 2006 Share Posted June 19, 2006 i need to replace 2 Geisseman 20k's 150w bulbs. i really like these bulbs but before i replace them i figured i would see if anyone has had any experience with any other brand that are similar or equal to these, at perhaps half the price? these run about $100 each. FWIW i do not run any supplement lighting on this tank, just two pendants. Link to comment Share on other sites More sharing options...
