So i have wanted to start planted aquarium journal for a couple of months. I finally got a 40 gallon breeder (petco dollar per gal sale) and bought a JBJ power compact light fixture of craigslist for 28 bucks. it comes with two sockets and there was only one 96 watt helios 10,000k bulb. I have gotten almost all my equipment (i have been patiently gathering for 4 months), and all i need is the bulbs and co2 system. I'm getting frustrated with the fact that i cant figure out what kind of bulb to get. Yes i have read a bunch of articles about par, pur, lumens, etc but i don't know where to find the proper bulbs for my fixture. If anybody out there could help me or suggest any good brand or bulbs that would be perfect for my hopefully future planted tank. Also, if you know any articles that might help me please put the link. Thanks.
So right now, i am caught in between keeping my light fixture or selling it ($50 offer currently), and i was wondering should i just get 96 watt 6700k from AH supply or should i just sell it and get a 4 bulb t5 fixture ? As far as i can see there are more bulbs to chose from if i get a t5 ho fixture.
