    Hmm I can't say for sure Clint. Probably would be ok but will cost an awful lot to keep buying those highend aquarium bulbs. They still contain alot of blue even though they are 'full spectrum', based on the color temperature near 10-12k.

    They do make coolwhite and daylight type(chroma 50 etc) in HO and VHO but you would have to order them from a lighting store probably. The other problem is they may not have the bipins to fit a standard fixture. No clue what a 48" chroma 50 in vho would cost but I would guess it's less than an Aquasun.

    If your only lighting a 4' area you might be better off considering a couple of the 65w 6500k compact fluorescent fluorex or reagent fixtures that homedepot/lowes carry. Will cost just a little more than 4 of those Aquasun tubes and the fixtures come with bulbs (which are replaceable and cost less than the specialty vho bulbs).

    well, i cant see replacing the balast when its only a year old and perfectly good. spending money to replace the bulbs isn't a problem. The endcaps will fit a vho bulb, i got a retrofit kit from a marine specialist aquarium store.

    could you tell me where i could find coolwhite and daylight vho bulbs, like could i order them from homedepot, walmart, or lowes?

    You might find them online but not sure from who. I have never used them but a search of sylvania, ge, phillips etc indicates they make several standard bulbs in HO and VHO styles. It would take a lighting store to order them, the retailers you mention wouldn't have a clue about them. I am also just guessing that a coolwhite in VHO is going to be cheaper than one of the specialty aquarium bulbs.

    If you decide to try and find the coolwhite or daylight type in VHO, you will need to check the connector type at the end of the tubes. There are many different ends besides the two prong types.

    BTW you can always add back some red spectrum if you go the aquarium bulb route.. just put a couple incandescent bulbs over the plants to turn on and off with the aquasun..

    Our local "Home Depot" stores here in Tucson carry VHO lamps, but not fixtures or ballast. [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_h_32.gif[/img]
