a little help please

[rockkfish]

i currently have 4 x 65 watt coralife light up and looking for new bulbs on ebay my bulbs are 21 inch does anyone know if the 22 inch are interchangeable... there is a 4 pack mix and match for 39.95 plus shipping that i'm looking over.

or if that is a no go there are some 21 inch odyssea bulbs will they work in the coralife setup??

any help is greatly appreciated

you need to make sure the pin configuration, as well as the wattage and length are the same. The brands themselves are interchangeable.
