went to litemore distributers 2 weekends ago in burnside (near halifax) nova scotia 902-468-1043
all prices canadian
sylvania qt 4x32 120is ballast electronic $28.00
sylvania t8 tubes 950 (5000k) 36 " $7.25 each
sylvania t8 tubes 865 (6500k) 36 " $5.25 each.
think i'll try a combination of tubes over my tank ie one 6500k and two of the 5000k, as this is what some people have advocated.
no hardware stores had any of the above. some of you in western canada or us might have had some luck at home depot, etc, but not me.
gulf coast: re your earlier statement, "I've talked to one or two that have run two three footers in series. Let me look more into it, since you may need an F40T8 ballast instead of an F32T8."
did you find anything out yet? thanks.
