20 gallon long lighting

[ibanez2k]

Well, I'm by no means an expert in lighting so I'd have to see the test results before I could determine if 4x24 watt T5s would be stronger than 2x65 watt PCs. I'm pretty new to reefing myself though so I'd take Fat Tony's advice if I were you. He knows his stuff. Best of luck with your tank!

can anyone tell me if this will be a good light for my new 20 long reef tank.

Coralife Aqualight Advanced Tank-Mount, 1- 150 W 14,000K HQI.

thanks,

Sounds good!

Yes, that would be a decent light for a 20 Gal.

It's all about the reflectors. It's not that the bulbs themselves are brighter (a PC bulb is essentially just a T5 bulb in a U shape) it just that the reflectors they use (T5's) are very efficient and allow more of the light from the bulb to make it to the tank.
