I have a catalina 4 x 54 T5HO over my 75 gallon. I have 2 bulbs on for the entire lighting period and the other 2 only on for a 2 hour "mid-day" period. The catalina has two switches to allow this type of setup. I have been very happy with my catalina light and recently bought another one. I have plenty of light and my plant growth has been great.

I was also worried that 4 bulbs was too much. It probably is for my setup, but I have the flexibility to grow anything I want. With the catalina, it is such a good deal (compared to tek) that I went ahead with the 4 bulb fixture and I don't regret it.

why is the fixture so inexpensive? is just because it has to be assembled?

I'm not sure why the catalina is so much less. It comes fully assembled. The legs are pretty flimsy, but otherwise it seems to be good quality. I've had mine now for 2 months with no problems.

I have not seen the tek light in person.

TAB

the only thing that comes to mind is

1 cheaper parts.

2 cheaper manufactoring process. using a press brake instead of a dye for example.

its either one or both of those.
