Considering this is for an AquaticLife 36" t5ho fixture, try searching for 36" lamps (aka bulbs) per the user manual.
FYI wave-point bulbs are actually cheaper on amazon than marinedepot, more so if you get their two-packs as the bulbs are less than $15 ea shipped. Marine depot also lists some bulb handling fees which amazon doesnt.
Don't get the 12000k bulbs for a planted tank. they may work great on reef tanks but wont benefit your plants as much.
why not pair up the tropical and red wave in your light setup?
