For $100, you can probably find a 4-bulb t5 on craigslist. It would be enough to keep most corals.

It depens how deep your tank is.. The deeper it is the more light you beed punched to the bottom. First decide what type of corals youd pike to keep then look at the lighting. 4 t5 will be enough for your size tank. You could add a couple of led just to giv it tht nice shimmer effect.

Checked out Aquatrader. They have some good deals. How is there service? Looking at the Reef Bright 48" LED. Anyone have any experience with Reef bright? Are they quality?

Dont get those reef brights. Its a rip off. Only good for fish only tanks. Stick with t5s unless the leds are 120 watts or more.

How do I know if a light will be sufficient for corals and anemones? Is it the temperature of the light, the wattage, the number of bulbs? What makes one light good for coral growth and another not good?

You want to take all those things into account when considering lighting options. It's all about the spectrum and intensity. In nature corals an nems are grown under the strong light of the sun so you want to mimic it as much as you can which is why many still use metal halides. as the depth of the ocean increases the light spectrum gets bluer which is why temperature is key also.

12k-20k is what you should aim for in a reef. You're ideal wattage should be 4-6w per gallon with t5s and 2-4w with LEDs. But PAR is the most important because that is how strong your lighting is. Only problem is PAR meters are real expensive. So measuring in watts is the next best thing.
