Why are these bulbs so hard to find? My tank is starting to change ( for the worst) and I strongly think that it is my 4 VHO bulbs. They are a little over 14 months old, and I have been told that even though the light is still bright, the bulbs should be changed every 6 to 8 months. When I go to find these bulbs, they are nowhere to be found and LFS all talk about doing a special order to get them. Is this the norm for getting VHO bulbs?
Is using this bulb becoming a thing of the past or is it still a great lighting source for a reef tank?
