Whoops, that's a different fixture, but it's probably the one you meant to recommend in the first place.
Identical diodes, but fewer. 54 diodes vs. 160 diodes in the one in the amazon link- huge difference.

Ah right, I didn't notice the different lengths. Sorry if this is getting confusing. I hope you haven't ordered the one in the amazon link already, it would be far too much light for low-tech. There is another 48" fixture with fewer diodes, similar to the 30" one in the link above but longer, which would be suitable. Go to the aquatraders.com site and browse around, I'm sure you find it. It's the "razor" series, 6500K.
It actually has a light mode that only uses half the lights, so there's always that. In any case I may just go higher light plants. As long as I don't have light levels that require pressurized CO2. I can use flourish excel and liquid ferts and root tabs.
It's a different series with more diodes. The "pent" series with rows of 5 diodes is usually considered verging on high-light. If I had to guess it's probably around 50 to 60 PAR at 18".
Running half (80) of the diodes is worth a shot. It might be on the low side of what will grow plants, but hopefully it will be sufficient. Running all 160 diodes will most likely be overkill without co2. I don't know the PAR ratings, so it's hard to say if you could get away with just excel or if you'd need to go with pressurized co2.You're definitely a little late, considering it arrived in the mail today
Yes. Not super high-light, but should be more like the high end of medium light. I think Brookster probably meant to link this model instead. It has only 96 instead of 160 diodes:
