light help questions

[heather1]

ok I am currently running 1- 28 watt 6700K T5 lamp and 1- 28 watt Colormax T5 lamp... I am in the process of upgrading to 4-T5, 54-watt, high-output grow light 6500K, 20,000 lumens. now before I purchase another t5 light fixture my question is will what I have be enough for my 55 gallon planned tank or should I buy another dual t5 light fixture (for a total of 6 t5 bulbs)?????

Aquarium Lighting T5 Fluorescent Light Fixture: AquaticLife T5 HO Dual Lamp Light Fixtures

This is the light I use on my 55 gallon. 48" with two 6500k bulbs. I am able to grow high light plants just fine.
4x54watt bulbs is A LOT of light, just be sure you really need it would be my advice.
