So I'm waiting for someone to pay me back the money I lent them, and I'm thinking of changing my light fixture... I currently have a 48" Odyssea T5HO 4x54w with built in timer, but the first 2 "sockets" have blown out leaving me with only 108w of total lighting with a crappy reflector which gives me around 40 PAR if I'm lucky lol. The fixture I'm thinking of getting is a 48" Green Element EVO 6500k LED fixture with 32x3w LED's which'll give me around 65 PAR @ 17" and because my 45 gallon tank is 48"x12"x19" I'll get at least 64 PAR lol.
The only bad thing about going with the LED fixtures is that it's harder to switch out the bulbs, and with T5HO it's easy to interchange the spectrums that plants need. But I could get the LED fixture, and use the T5HO fixture for a single WavePoint Ultra Growth Wave bulb which will give me both the 420nm and 660nm spectrums that plants use for chlorophyll A & chlorophyll B.
