You really need to find another supplier. I Recently got 48" GE SPX50's
at $5.20 apiece and 24" at $6.20 these are rated a 5000k and 85CRI. The
electronic parallel ballast at 120w was only $63.00
BTW the hood I built for my 55g flat back pent tank is fantastic and the
plants are really loving it. (Had to brag a little :-) )
