Suggestion: Light for 120G - 4x2x2

[Dana Riddle]

If you're looking for LED luminaires based strictly on price, go with Chinese LED 'black boxes' that offer a built-in timer and spectral adjustments on at least 2 channels ('blue' and 'white.')

How do you guys control T5's bulb? Timers?

Yes, just a basic programmable timer to turn them off and on at whatever time and duration you want.
